Which is the easiest way to limit the number of characters allowed to type in a textarea input field? My textarea input field looks like this: <textarea name="body" id="textareatest" style="width: 300px; height: 75px">Type text here. (limit 150 characters)</textarea> Is there an html attribute that will do it, or do I use javascript? Thanks, Jakob

There is no html attribute for that, you'll have to use javascript to do it. You could have a function that would be called on each keypress and then deleting the character pressed if the maximum length was reached.

Ok, thanks. Something like this?: <textarea onkeyup="if (this.value.length > 150) this.value = this.value.substring(0, 150)"> Jakob

yes, I believe that should work

It works, though you can cheat it by copy/pasting some content to the field. (Of course you'll have to use the right-click menu and NOT the CTRL + V shortcut...) Add the onchange attribute with the same functionality to avoid this exploit.
