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.
