Max charcters in textbox.

Copy linkTweet thisAlerts:
Feb 10.2003

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

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.[/font]

@twixy2kauthorFeb 10.2003 — 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
