Maximum length of a text field

cwolgamott · Jun 19, 2002

Hello.

I am creating a web page and I would like to set a maximum length of a text field so that the user can only enter the number of characters that I allow, and then does not let them enter anymore after that maximum has been hit. I have tried setting the Char Width and Num lines, but this does not stop the user from entering more than the limit. I would greatly appreciate any suggestions or help.

Thank you.

Try this

Code:

<input name=&quot;yourname&quot; type=&quot;text&quot; maxlength=&quot;10&quot;>

Thank you so much for your reply.

I greatly appreciate it. I have another question though. How can I get that to work with a multiple line text area? I would greatly appreciate any suggestions that you might have.

Thanks again.

Hmmmmmmm..

Good one

You might want to do some javascript form validation. But I think that will only work after the user tries to submit the form, it wont stop them entering more than a set number of chars.

I will have a look for a script to do something for you.

OK here goes.. this checks to see if there is more than 100 chars in a text area before submitting a form

insert this into the

Code:

<head>

section

Code:

<!--
function validateform()
{
if (document.yourformname.yourtextareaname.value>&quot;100&quot;)
{
window.alert (&quot;The Text area has over 100 characters in!!&quot;)
return false;
}
}
//-->
</script>

and your form tag should have this in:

Code:

onSubmit=&quot;return validateform( this.form )&quot;
