Scryptik javascript editor and validator

"Save Time Fixing Javascript Errors!"

ScrypTik is a shareware program for Windows™ that is a source code editor with a built in javascript parser to check, verify and validate your Javascript syntax. The Javascript code may be anywhere in the (x)html (functions inside <script> tags, include files or inline) and it will be extracted and validated. There is a 20 usage free trial, so download and try it out. This Javascript authoring tool could save you hours of frustration! This error checking is ideal for learners (especially programming beginners) and teachers of Javascript programming. Note, throughout this web site references to Javascript apply equally to JScript, ECMA-Script and ECMA-262. Also, it is not usual to refer to "Javascript" using two words - "java script".
 
You may have reached this site because you were trying to find "www.scryptik.com". Unfortunately that site is no longer available due to the incredible behaviour of a domain registrar called RegisterFly. ScrypTik remains fully supported from this new site. You can contact us here at our new email address. Update June 2007, Godaddy bought the Registerfly remnants and have saved the day!

Example


The first indication of an error is a small warning icon in the lower left corner (status bar) of your browser such as this:
Double clicking the icon produces the dialog (you need to click "Show Details>>"). Javascript editor
This type of feedback can be difficult. The HTML file which is being displayed here is shown below in the ScrypTik editor. The error pane shows what is wrong in a user friendly way, and saves time by avoiding a trip to a browser to find errors.
ScrypTik java script editor A Javascript function is being called , initMyPage(), which cannot be found because it is declared with a lower case "p". The problem is presented to the user in a much clearer way than "Line: 15 Char: 1 Object expected" and it can be fixed and syntax checked in the editor immediately.

ScrypTik javascript validator is not primarily intended to be a front-line web page authoring tool although its quite capable for a non WYSIWYG editor. It is aimed at catching the syntax errors that inevitably occur when incorporating Javascript into HTML.

Javascript libraries

Currently, several comprehensive Javascript libraries are receiving attention from web developers for Web 2.0 "richly interactive features" and AJAX implementation. Also, they insulate the web developer from the erratic and "non-standard" behaviour of the popular browsers. Below is a typical example of tabs providing access to different content. The content associated with each tab fades smoothly in and out as tabs are clicked. These were created using the "Tabs" plugin for jQuery from Klaus Hartl http://stilbuero.de/tabs/. These tabs record usage in browser history so the "back button" behaves as a user would expect (the jQuery plugin for this is "history_remote").

Jquery from John Resig and the jquery team. I use jQuery because it is packaged with the CMS I use (Drupal). I wrote a module to only include the plugin and associated css on specified pages.
MochiKit, a lightweight Javascript library. The slogan on their website is "MochiKit makes Javascript suck less", an interesting view, faint praise . . . !
Dojo is an Open Source DHTML toolkit written in JavaScript. It builds on several contributed code bases (nWidgets, Burstlib, f(m)), which is why we refer to it sometimes as a "unified" toolkit. Dojo aims to solve some long-standing historical problems with DHTML which prevented mass adoption of dynamic web application development.

Their website is Drupal too, jquery and dojo playing together!
Prototype is a JavaScript Framework that aims to ease development of dynamic web applications. Featuring a unique, easy-to-use toolkit for class-driven development and the nicest Ajax library around, Prototype is quickly becoming the codebase of choice for web application developers everywhere.

Its development is driven heavily by the Ruby on Rails framework, but it can be used in any environment.
The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources. All components in the YUI Library have been released as open source under a BSD license and are free for all uses.

Their website has fantastic video presentations from Douglas Crockford and others on Javascript, the DOM and browsers in general, I recommend them.
I guess all Javascript programmers are interested to know what libraries are being used. If you use one of these libraries, please vote for one listed below. If I have omitted a popular library, please drop me an email and I will add it.

All the errors, warnings and hints

A list of over 200 possible problems reported by ScrypTik javascript validator including dialogs, hints, warnings and errors.
Notes:
  • The letter "n" means some number, usually a line number.
  • "identifier" means a user defined (programmer) name for a variable, function, object property or method etc.
  • Some errors are dependent on the options selected, eg the warning for declaring global variables inside a function is optional.
  • Sometimes the line number reported for an error is beyond where the error actually is. This is because parsers are expecting something which may be missing, and by the time it is realised that it is missing, the parser is examining the next line or beyond. Mostly this is caused by a missing semicolon on the previous line.
  • The "parsing stopped, correct previous error(s)" means the parser has got stuck. These situations are being corrected (if possible) as they are discovered. Please note the code that causes this and submit a bug report.
Application Dialog Errors
Explanation
File "FileName'' does not exist Can only happen when opening a file from Windows Explorer and Windows dde fails with the association somehow.
This file has been changed by another application! OK to Re-load this file now? If you edit and save this file with another application eg notepad, then you get one chance to re-load it. Very confusing to edit the same file concurrently from different applications, you can easily lose changes.
File: "FileName" is already open! ScrypTik does not allow the same file to be opened more than once. It is too confusing to have the same file opened more than once, eg saving a copy that does not have the latest changes.
File: "FileName", has changed. Save now? Content has changed, you can save changes or discard them by not saving.
Document "Name" has changed, do you want to save before viewing in Browser? If you do not save before viewing in the browser, you will not see the latest changes.
File "FileName" not found, must Save before viewing. A new file must be given a name and saved before viewing.
No further occurence of ''SomeText'' found. Repeat search (F3) could not find another occurence.
File extension not same as selected filter. Please confirm you wish to save file as "?????" The filters are .htm, .html, .js etc. If you select a filter and name your file using a different extension, this warning appears.
File: "FileName" is already open! ScrypTik does not allow you to "Save As" this name. Can't save as a file that is already open in ScrypTik.
File: "FileName"' no longer exists. This entry will be removed from the Reopen list. ScrypTik remembers the last 10 files worked on. A file in the reopen list has been deleted or moved. The list entry will be removed. You will have to locate it and open it using "open".
No browser selected! If a choice of browser is offered at view time, you must select one to proceed.
Table not complete, non numeric entry in table details Could not create HTML table because an entry in one of the numeric fields (cols, rows, border etc) was invalid.
List not complete, non numeric entry in list items Could not create HTML list because an entry in one of the numeric fields (number of items) was invalid.
Non numeric entry in margin details The print dialog has options for margin size. An entry for one of them was invalid.
#
Syntax Check Hints
Explanation
1
recommended to avoid an identifier name of "identifier" The list of names to avoid is checked for every variable, parameter etc. The list is a subset of the DOM keyword list. This is probably a redundant check.
2
recommended to use "var" when declaring variables in a function, "identifier" will be treated as global! In Javascript, variables may be created without using the keyword "var". If the "var" keyword is omitted when declaring variables inside a function, then those variables are global, not local.
#
Syntax Check Warnings
 
10
unknown escape sequence "\" + Character, (maybe a correct URL or file path) The valid escape codes are:- \b, \t, \n, \v, \f, \r, \", \', \\, \000 (octal number 0 -377), \xHH (hex), \uHHHH (unicode) where H is a Hex value (0 - F)
11
local var "varName" already declared on line n Declaring the same variable again - warning only.
12
local var "varName" same name as a function parameter A local variable "shadows" a parameter by using the same name. Very likely an error.
13
missing semicolon If the option to warn on every missing semicolon is active, this message appears for every line with a missing semicolon.
14
duplicate function - "functionName". Browsers will use the last one without reporting any error! You may have several functions named the same and browsers do not report any error. Not a good idea!
15
empty block "{...}" or missing "{" in function Function may be under construction - warning only.
16
the "arguments" property of functions is deprecated Meaning this will eventually not be a feature of later versions of Javascript and therefore use of "arguments" is not a good idea.
17
ECMAscript doesn''t allow line terminators between "throw" and expression To adhere to ECMA you can't have a line-break between "throw" and expression.
18
catch Id same name as a function parameter Catch Id should have a unique name.
19
catch Id same name as a local variable ditto
20
catch Id same name as a global variable ditto
21
Identifier named "Var" is probably meant to be keyword "var" Possible typing error.
22
variable/function name "identifier" is a reserved word or DOM object Should not use Javascript reserved words, preferable not to use DOM object names.
23
global var "identifier" already declared on line n Declaring the same variable again - warning only.
24
";" after "if (expression)", "if" now redundant The semicolon terminates the if which is probably not what you want.
25
empty block in "do . . while" No statements inside do . . while, maybe under construction.
26
should probably be test for equality "==" not assignment "=" Common mistake to use one = (assignment) when you should use two == (are two values the same?)
27
";" after "while (expression)", will only loop expression instructions The semicolon terminates the while which is possibly not what you want.
28
"while" empty No statements inside while loop body, maybe under construction.
29
";" after "for", will only loop instructions inside ( ) The semicolon terminates the for which is possibly not what you want.
30
empty "for" loop body No statements inside for loop body, maybe under construction.
31
preferable to have expression and ++ or -- on same line If your code ever encounters automatic semicolon insertion, you risk an error.
32
empty array initialiser Warning only.
33
invalid array index expression The expression inside [] is invalid.
34
Include File "FileName" has been changed but not saved When checking syntax, ScrypTik always reads include files from disk, NOT from the editor.
35
HTML Name "identifier" missing "]" An HTML named element has an opening index [ without matching ].
36
tag name/id "identifier" is a DOM property/method Try to avoid using these names.
37
HTML Name/Id "identifier" is duplicated Browsers don't seem to mind this, but it does not seem exactly "robust"!
38
Name and Id attributes have different values "HTMLName" & "HTMLId" Warning only.
39
check number of equals ("=") symbols (or "s)) HTML tags with attributes are checked for the number of "=" symbols being the same as the number of attributes. It is better (compulsory in XHTML) that every attribute value is quoted (inside ' or ").
40
Form name/id "FormName" is a DOM property/method Try to avoid using these names.
41
</form> tag found without preceding <form> tag (maybe in dynamic HTML) Tag pairing, should normally match unless the opening <form> tag is created dynamically.
42
</script> tag missing No closing tag found for a <script> tag.
43
</form> tag missing No closing tag found for a <form> tag.
44
HTML comment tag never closed with a "-->" tag This can mean that large parts of a document are ignored because they are treated as a comment. May need a closing comment tag.
45
HTML object "identifier" referenced earlier than declaration on line n. Global or inline Javascript code which refers to HTML objects that are at higher line numbers than the code can cause browser errors. Move the <script> section to after the closing body </body> tag.
46
function "functionName" not called from Javascript or HTML Maybe a redundant function that you can remove, or maybe about to be used.
47
possible HTML closing comment tag "-->" found within script If it really is meant to be an HTML comment, then it should be preceeded by a Javascript/Jscript comment symbol "//".
48
The update part of a "for" loop should change a variable by assignment or pre/postfix operator. Usually the third part of a for ( ; ; ) changes something eg count++.
49
space between < and input causes problems with some browsers The word "input" must be immediately after the opening tag symbol "<".
50
empty block or missing statement in "if" No statements after "if", maybe under construction.
51
empty block or missing statement in "else" No statements after "else", maybe under construction.
52
function name "identifier" is duplicated in HTML Names Some browsers don't like Javascript function names duplicating HTML object names.
53
function "identifier'" is an object method Object methods should only be called via an object instance, not directly.
54
return expression missing or invalid Missing or faulty expression following a return instruction.

What our users say

Read what two course controllers at tertiary institutes say about using ScrypTik javascript editor and validator for teaching advanced web application development.
 
"I have used ScrypTik with our Advanced Web Application development course, a second year degree course which involves advanced HTML, cascading style sheets and Javascript. We have up to 48 students and they all found ScrypTik easy to use and very productive."
 
Stephen Corich MBS, BSc
Course Controller

"At Whitireia, ScrypTik has made Javascript (and with it, elementary programming) accessible to a wider range of students. An otherwise arcane topic has been rendered colourful, interactive and fun, working in that most familiar of environments - a web page. The user interface is simple and intuitive, yielding instant feedback on defects in code. Its likely that browsers will become less tolerant of sloppy code; in this regard, ScrypTik is one step ahead by enforcing these standards now."

A. You run ScrypTik and from the "File" menu select "Register ScrypTik". This screen will show you the machine code and instructions on registering.
 
Q. Why do I get an error running my script in my browser when ScrypTik reports no errors?
 
A. ScrypTik checks (validates) the syntax and some semantics of all Javascript code. It is still possible to get "run-time" errors with logic mistakes such as null object references. This behaviour is no different from most other programming languages. Edit, compile and test, that's software development.
 
Q. Why is it called "ScrypTik"?
 
A. Any or all of these:

  • It sounds (and is spelt a bit) like "cryptic", and computer programming often seems cryptic to beginners.
  • The "Scrypt" part is similar to "Script" and we are dealing with a scripting language.
  • The "Tik" part sounds like "tick" which is a universal mark for correctness, so ScrypTik can give your code a stamp of approval! (The program icon is a tick too.)
  • Its just a name!

 
Q. What are tokens? Why does it tell me how many tokens there were after a check?
 
A. A token is a parsed item of javascript, each keyword, symbol, literal, variable etc is a token. The token count indicates how much javascript code there is, most people will ignore it.
 
Q. I had to replace my hard disk drive and after re-installing the operating system and ScrypTik, the registration code no longer works?
 
A. This is because the machine code is generated from various hardware serial numbers and it will have changed. E-mail our support to get a new registration code. You will need to supply the new machine code and the name you originally registered under. We will then give you a new registration code.
 
Q. Will ScrypTik run on a local area network (LAN)?
 
A. Yes, there are two multi-user licenses, either 2 - 10 users or 11+ users. Install (ie run the setup.exe once unzipped) on a server. Give workstation users a desktop shortcut and/or a menu item which links to the exe on the mapped network drive (the server). Each user will have their own ini file stored on their personal drive in a folder named "ScrypTik". An alternative is to install the exe on each workstation and the ScrypTik License Server (ScryLSrv) on a server. After configuring IP and port number for both server and workstation (plus retry count and other protocol stuff), each workstation ScrypTik will check with the License Server for registration when it starts execution. Contact us if you require the License Server.
 
Important, when supplying the machine code to register multi-user ScrypTik, it must be the machine code from the "server" machine, not one of the workstations where you trialled the software. It is easy to inadvertently use the trial machine when registering, as the trial is designed to only run on a local machine, not from a network drive.
 
Another option once you have a multi-user license, is to just get as many unlock keys as you require, one for each workstation. Again, just email us and we will supply the keys.
 
Q. How have you tested ScrypTik?
 

A. The basic test data is all the samples (about 300) from Danny Goodman's "Javascript Bible". Then there are additional tests for object oriented issues and nested functions.

Known issues

These are the currently known issues that can trip up the validator (and the user!).

  • Frames, ScrypTik is currently designed to work with a single HTML file and any of its javascript code in *.js include files. If a HTML file which is part of a frameset refers to an identifier in another file in the frameset for example "parent.propertyXyz" then "propertyXyz" will not be found. ScrypTik can treat groups of files as a "project" and depending on feedback, could syntax check them together.
  • There are literally hundreds of Built-in, Browser and DOM properties and methods attached to the various HTML <tag>s, some are obscure to say the least. Eg, the <img> tag has a property called "loop". ScrypTik copes with the more common DOM properties and methods and the list is added to frequently as more samples of code are tested (there are now over 750). You may get false errors as unrecognised DOM properties and methods are incorrectly interpreted as user-defined identifiers. You can see an alphabetic list of the properties and methods checked from the "view" menu or editor pop-up menu. A side-effect of this large number of DOM "keywords" is that it is very easy to inadvertantly use one as a user-defined identifier, eg "width". ScrypTik warns about this usage and it would seem preferable to avoid the DOM "keywords" as identifiers.
  • Layers are not resolved correctly which results in errors. Depending on feedback ScrypTik could keep a list of Layer names and reconcile them.
  • Regular expressions (between the / . . . /) are not thoroughly checked. Also, quotes within a regular expression constant cause highlighting weirdness (will be fixed, maybe regexp constants get their own color?).
  • Dynamic HTML created by Javascript which constructs names and id's may produce errors as the names cannot be reconciled. ScrypTik is a parser and has no concept of what happens at run time, e.g.
    for(var i=0; i<10; i++)
          document
    .writeln("<input type='text' name='frmInp" + i +"' size='20'>");

    then if there is a statement like this:

        var xyz = frmInp3.value; // frmInp3 will not be found

  • If objects are passed as parameters, and constructors assign the parameter to properties or methods, then the parser has no idea that the property or method is itself an object. A work around is:

    function anObject(param1, param2) {
      this
    .anotherObject = new AnotherObj(); // this sets up anotherObject
      this
    .anotherObject = param1;
      .
      .
      .
    }
  • Table column identifiers created with <th>identifier</th> tags are not extracted and reconciled. Therefore when these identifiers are referenced they will be unresolved and give syntax errors. Maybe fixed depending on feedback.
  • An XHTML tag such as this: <input type="radio" name="btn2" checked onClick="normalColor()"> will produce a 'check the number of "=" symbols . . ' error. Browsers are happy with just checked, interpreting it as checked = "checked", however ScrypTik requires an equals sign following checked. Note that XHTML will insist on the long version of checked = "checked".
  • If HTML syntax highlighting is selected, the highlighting of </script> when this tag does not start on a new line is ignored. This means that all highlighting continues with whatever has been set for Javascript. A workaround is to make the </script> tag start on a new line. Will be corrected in a future version.
  • Variables constructed with eval( ) can't be reconciled, so ScrypTik parser may report false errors. ScrypTik can only validate syntax and has no knowledge of what happens at run time.
