string.length

[wsmall73]

I am trying to write a custom validator using javascript and I am simply trying to determine the length of what should be a string...

function ClientValidate(source,args)
{

alert(""+args.Value.Length);
args.IsValid=true;
}

I added the ""+ to try to ensure that it was forced to a string but I am obviously missing something.. any assistance would be greatly appreciated. TIA

The correct syntax for checking form field length is document.formfieldname.value.length. (Note that value and length are lower case.) Without knowing what source and args are, and how you're passing them to your function, it's a little difficult give you a firm answer.

There's always a better way. The fun is trying to find it!

The correct syntax for checking form field length is document.formfieldname.value.length

Maybe if you want your code to function in IE only... This would be a much more correct way of doing things:

document.forms['formName'].elements['formFieldName'].value.length

Hope this helps,
