Javascript, Error: "Object Required"

May 9th, 2008, 9:16 am

I'm getting this error by double clicking the warning icon present in IE's window (bottom left). It points to line 36 and "Char 3" whatever that Char 3 means is beyond me.

Has anyone got an idea whats wrong with the following code.

Line number On/Off

Code: Select all

1.  
2.  
3. function __isValidEmailAddr(email)
4. {
5.     var filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
6.    
7.     if (filter.test(email))
8.         return true;
9.     else
10.         return false;
11. }
12.  
13. function __checkContactForm()
14. {
15.     var _name = document.getElementById('name').value;
16.     var _email = document.getElementById('email').value;
17.     var _comments = document.getElementBy('comments').value;
18.     var _errorTrigger = false;
19.     var _errorMessage = '';
20.    
21.     if ( _name = '' )
22.         {
23.             _errorTrigger = true;
24.             _errorMessage += '\n~ You must provide a name';
25.         }
26.     else if ( _name.length < 3 )
27.         {
28.             _errorTrigger = true;
29.             _errorMessage += '\n~ You must provide a legitimate name';
30.         }
31.    
32.     if ( __isValidEmailAddr(_email) == false )
33.         {
34.             _errorTrigger = true;
35.             _errorMessage += '\n~ You must provide a real email address';
36.         }
37.        
38.     if ( _comments = '' )
39.         {
40.             _errorTrigger = true;
41.             _errorMessage += '\n~ You must provide a message';
42.         }
43.     else if ( _comments.length < 10 )
44.         {
45.             _errorTrigger = true;
46.             _errorMessage += '\n~ You must provide a legitimate message';
47.         }
48.        
49.     if ( errorTrigger == true )
50.     {
51.         alert('\nThe following error(s) were discovered prior to form submission.\n' + _errorMessage + '\n\n');
52.         return false;
53.     }
54.    
55.     delete _name;
56.     delete _email;
57.     delete _comments;
58.     delete _errorTrigger;
59.     delete _errorMessage;
60.    
61.     return true;
62.    
63. }
64.  

Whilst on the subject, can anyone recommend me a javascript debugger, I've only IE's error messages to go on at the moment.

Line number On/Off

Code: Select all

1. function __isValidEmailAddr(email)
2. {
3. ...

You see what I highlighted in blue? When you are calling on that function... are you giving it the email? Something like...

Line number On/Off

Code: Select all

1. <form action="contact.html" onSubmit="javascript&#058;__isValidEmailAddr(email@site.tld)">

Yeah, I know that the email may change so you might need to change the javascript a little bit.

I think that this may be your problem...

Not sure if this is it, but it's definately wrong.

Note "getElementBy".

Line number On/Off

Code: Select all

1. var _comments = document.getElementBy('comments').value;
