This is a simple but effective script for extending your textarea with a
maxlength attribute, so the user's input cannot exceed a certain number of
characters. Works with any number of textareas on the page.
Step 1:
Add the below script to the
<HEAD> section of
your page:
<script type="text/javascript">
/***********************************************
* Textarea Maxlength- © Jooria Refresh Your Site (www.jooria.com)
* This notice must stay intact for legal use.
* Visit http://www.jooria.com
***********************************************/
function ismaxlength(obj){
var mlength=obj.getAttribute? parseInt(obj.getAttribute("maxlength")) : ""
if (obj.getAttribute && obj.value.length>mlength)
obj.value=obj.value.substring(0,mlength)
}
</script>
Step 2: Inside any textarea you wish to add a "maxlength"
attribute to, simply do the following:
<textarea maxlength="40" onkeyup="return ismaxlength(this)"></textarea>
The part in red is what you should add, with "40" obviously
being the maximum number of characters accepted by this textarea.
Enjoy!
