I get errors for Java Scripts

[ashishsmith]

I have a Java Script in my Cold Fusion page where I am limiting 3 fields to 500 characters and Java Script is used to truncate the field. It works fine on all computers except one and in there whenever my cursor enters the field with Java script and I start typing something It gives me an error. I don't know why. I have checked the security settings of Internet Explorer and also Advanced options. But still it is not working. Does any body have suggestion on that. Did any body had the similar problem?

What error do you get? What browser are you using when you get that error? Can you provide a link so someone can take a look?

Well, I can't send you the link because it is an internal page, I mean it is on intranet and not on internet. Sorry for that.

But I can explain you the error

Error : 'undefined' is null or not an object



This is the error I get when I press a key in the field where Java Script checks if the characters in the field have gone over 500 characters or not.

I hope this gives you a clear idea what is going on.

It happens when a key is pressed in the field, that means when Java Script starts.

Thank you for your reply

You would be best to at least post some of the java so some one can help you. Javascript errors are incomplete and tell you little of what is really going on.

Best of luck

Ok here is my code to limit text area to its maximum limit if the user goes beyond the max limit

<!--- START: JAVASCRIPT: Limit TextArea --->
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function textCounter(field,cntfield,maxlimit) {
if (field.value.length > maxlimit) // if too long...trim it!
field.value = field.value.substring(0, maxlimit);
// otherwise, update 'characters left' counter
else
cntfield.value = maxlimit - field.value.length;
}
// End -->
</script>
<!--- END: JAVASCRIPT: Limit TextArea --->

<SCRIPT LANGUAGE="JavaScript">
<!--
  function textCounter(tfield,cntfield,maxlimit) {
    if (tfield.value.length > maxlimit) {
      tfield.value = tfield.value.substring(0, maxlimit);
    } else {
      cntfield.value = maxlimit - tfield.value.length;
    }
  }
-->
</script>

Try this.. Its a slightly modified cleaned up version of your code... The primary thing I did was { bracketed } your if statement and got rid of some of the comments.

For the heck of, I also changed the name of the parameter from field to tfield. Its habit, I try not to use real words as variable names. That makes dodging reserved words easier.

Obviously its a parsing problem the with computer if everything is is alright. So cleaning out all the excess may help.

This doesn't work, my friend.

Thank you atleast for trying to help me.

Oh one more thing if you can help me in this.

I have a print icon, which prints the records. I want to print them back to back. Is there an option where i can straight away load that option as checked through java script.

Thank you,

This is a dumb question, but does that one computer that gives you this error have JS enabled?
