return true;
else{
if (keyval == 8 || keyval == 0)

I have an HTML form with a textarea. When passing large amount of data in the textarea, the Processing asp pages catch an error message as follows: Error Type: (0x80020009) Exception occurred. The error is generated once the trim or length or replace function is called on the field when long text is passed in the textarea.

Hi all, I find a JavaScript that limits the field length in a textarea, but it is not completed. The script does not handle the copy and paste case. For example, says the textarea field length is limited to 5 and a 6-character length text is pasted, no event is triggered. (The script only handles onKeyPress and onKeyUp)

I have a textarea that must be limited to 70 characters. No big deal -- at least so I thought. * Textarea must not exceed 70 characters * Exceeding content must be cut off * Must work on input by keyboard (keypress, keyup events) * Must work on pasted input from context menu * Must work on pasted input via CTRL+V and similar * Must work on pasted input via browsers menu>Edit>Paste * Must work in Mozilla + IE and coded via W3C standards

This is in the head: <script language="javascript" type="text/javascript"> function limitText(limitField, limitCount, limitNum) { if (limitField.value.length > limitNum) { limitField.value = limitField.value.substring(0, limitNum); } else { limitCount.value = limitNum - limitField.value.length; } } </script>

I need to emulate the missing "maxlegth" attribute in "textarea" fields but all my Google searches either lead to obsolete scripts that overwrite the "value" property (thus losing caret position) or to complex solutions that work on top of specific frameworks. Do you have some reference on how to do it? I'd like to make it work in at least Firefox and IE 6 and 7. Thank you in advance,
