I need this character count to NOT include spaces typed in each of the 4 fields.

Can you help?

Thanks! :)

MY CODE:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "<html xmlns="<head>
<title>Untitled Document</title>
<script type="text/javascript">
function countChars()
{
document.form1.count_display.value = (document.form1.text_1.value.length + document.form1.text_2.value.length + document.form1.text_3.value.length + document.form1.text_4.value.length);
}

</script>
</head>
<body>
<form action="" name="form1" id="form1">
<p><input name="text_1" onkeyup="countChars();" onblur="countChars();" /></p>
<p><input name="text_2" onkeyup="countChars();" onblur="countChars();" /></p>
<p><input name="text_3" onkeyup="countChars();" onblur="countChars();" /></p>
<p><input name="text_4" onkeyup="countChars();" onblur="countChars();" /></p>
<br />
<p>Char Count: <input type="text" name="count_display" value="0" size="4" readonly="readonly" /></p>
</form>
</body>
</html>
 
You can try it using a replace method:
Code:
...
var frm = document.form1;
frm.count_display.value = frm.text_1.value.replace(" ","").length + frm.text_2.value.replace(" ","").length + frm.text_3.value.replace(" ","").length + frm.text_4.value.replace(" ","").length;
...
The code is hardly optimised, but it ought to show how you can use replace to replace all spaces (" ") with an empty string ("").

Cheers,
Jeff

Make sure your web page and css validates properly against the doctype you have chosen - before you attempt to debug a problem!

[tt]function countChars()
{
var rx=/\w/g;
var s="";
var n=0;
with (document.form1) {
for (var i=1;i<5;i++) {
s+=elements["text_"+i].value;
}
if (rx.test(s)) {
n=s.match(rx).length;
}
count_display.value=n;
}
}[/tt]
 
In case the above filtered too many, you can use an expression strictly excluding blankspace nothing else.

[red]//[/red]var rx=/\w/g;
var rx=/[^ ]/g;
[/tt]
But one can image whole spectrum of filter between the two limits.
