What about this (untested):
$('textarea').change( function()
{
$(this).prepend('Current length: <span id="' + this.id +
'_len">' + this.value.length + '</span> characters');
$('#' + this.id + '_len').css('color', (( this.value.length >
parseInt( this.id.split()[1] )) ? 'red' : 'green')).html(
this.value.length )
});
There's probably a chainable way to grab that new span id after the
prepend fcn, but as I said, untested...

Subject: Re: [jQuery] Textarea character count
Thanks for the link.
Here's what I came up with:
$(document).ready(function(){
$('textarea').prepend('Current length: <span id="'+ this.id
+'_len">'+this.value.length+'</span> characters').keypress(
function()
{
$('#'+this.id + '_len').css('color', ((this.value.length
>
parseInt(this.id.split()[1]))?'red':'green')).html(this.value.length)
} )
});
<textarea cols="54" rows="5" id="Desc_512"
name="Description">SPORK</textarea>
I'm not sure you can generate a selector dynamically, as I did in the
keypress function. It seems to be choking on the this.value element as
well.
It would be really neat if this worked :) Any advice would be
appreciated.
I just want to understand how jquery thinks.
