[cfaussie] RE: Help with validation code...

[Steve Onnis]

Here is my effort

Been playing around with prototypes of late so I thought this would be fun

<script>
        String.prototype.hasCrap = function () {
                var inStr = this.match(/[^a-zA-Z0-9]/g);
                if (inStr)
                        {return true;}
                else
                        {return false;} 
                return true
                }
                
                
        str = "thisisastring";
        alert(str.hasCrap())
        
        str = "this is a string";
        alert(str.hasCrap())
</script>

This way the hasCrap() function becomes a method of the String object, so you can call 
hasCrap() as a method of any string

So in your case

if (document.particulars.username.value.hasCrap()) { 
       alert('Please Enter a Username'); 
       return false; 
   }

Subject: [cfaussie] Help with validation code...

Hi All,

Just wondering if you could give some help with some javascript code 
please.  I have some form validation code which simply sees if a field is
empty or not: 

if (document.particulars.username.value == "") { 
       alert('Please Enter a Username'); 
       return false; 
   } 

But what can I add to see if the username field contains the character ';'
or has any spaces.  If it does contain any of these, it must bring up an 
error. 

Help would be greatly appreciated.

Thank you.
