Max charcters in textbox.

[twixy2k]

Hey, Is there a way to trim all the charcters in a textbox after a certain amount or after a certain character. To populate the textbox i have sessions inserting in the init. value. I want the max charcters to be 5. The normal

<input name="setname" type="text" class="insertshowsize" id="username" value="<%= Session("user") %><%= Session("svuser") %>" size="5" maxlength="5">

doesn't work.
It could be trimed onLoad, Submit etc.
Thanks
Alan

<form action="someScript.pl">
<div>
<textarea rows="5" cols="15" onchange="this.value=this.value.substr(0,25)">
</textarea>
</div>
</form>

That will clip entries in the field to 25 characters in length but it will fail for 12% of users. If this clipping thing is important then you will need to also do some server side form validation.

The textbox it self is not going to be clicked in or edited. How do i name the text box then trim it from a onchange command in another text box, or submit button click. Possible?
Thanks
