Form counter & prefilled form field

[Ben Barnes]

Hi,

Having an issue with a pretty standard javascript text counter. The
counter works fine when a user physically enters text into a textbox
but shoudl the textbox have a value prefilled then the prefilled value
is not taken into account until the user has entered something in the
textbox.

So basically I have a textbox with "hello" in it and a text counter
which say "10" it is not until the user clicks on the textbox and then
presses key or chnages the text that the counter updates and takes the
"hello" into account, thus chanign the textcounter value to 4 as the
user woudl have pressed the spacebar in this example.

Hope this makes sense. has anyone got any idea on how I can get around
this?

Hi Ben.

Where is the 'prefilled' text coming from? If it's being printed at the
server, the same routine could also initialize the counter. Otherwise,
you can always set an onload handler for the page that explicitly calls
the HTML event handler property involved, e.g.

<input id="foo"....onchange="textcount(this)" />

....can be called:

window.onload = function()
{
document.getElementById('foo').onchange();
}

Hi,

Thanks for taking the time to write.

The text has a value set dynamically from a users input. The problem is
this can change to any length but the counter has a set value which
does not take into accoutn what he user has entered.
I'll give what you have suggested a shot.

Thanks
