You have two options depending on how you want the data to be manipulated.

1) Event driven function applied to TextField_Change()
You can drive code here that will be driven every time the user enteres a new value for the text field.

2) Event driven function applied to TextField_LostFocus()
Once the user has entered whatever value in the text field, and either TAB'ed out of the field or pressed enter, the value is captured in this function

Here is a simple sample:

Function MyTextField_Change()
MsgBox me!MyTextField
End Function

: Every time you enter a Char or Number, Space or whatever, the msgbox will pop up to display the contents of the field

Function MyTextField_LostFocus()
MsgBox Me!MyTextField
End Function

:Once the user exits the field (by TAB, Enter or even mouse clicking another field, the msgbox captures the contents of the fiel and displays.

Now simply replace your code with my MsgBox calls, and the funciton will do the rest!

i am still hazy on what i need to do..

here is the code i am trying to execute (Cold fusion is involved)

<html>

<title>Untitled</title>
<script>

function getval() {

//--- i dont know how to write a function that will submit the form element 'nu'

}
</script>
</head>
<body>
<form name=fu>
<input name="nu" onchange="getval()">

</form


<cfoutput>
<cfif isdefined ("form.nu&quot

>
the value of the form is #form.nu#
</cfif>
</cfoutput>

</body>
</html>

Hi macmac1

What birklea answered is correct.He explained it very clear.
If you want to catch the value of the field 'nu' every time the user changes its contents,you should use the 'onchange' event handler.
If you want to get the value of 'nu' every time the user click in other field,or press tab or enter,you should use the 'onblur' event handler.
Once you decided how you will manipulate the user's action,
you can get the value of 'nu' easily'

Here I assume you wish to get the value of 'nu' when the user enters in other field,just clicking on it,pressing tab or enter.If you wish the other case,just replace 'onblur' by 'onchange' in your form.

<html>
<title>Untitled</title>
<script language="javascript">

</script>
</head>
<body>
<div align="center">
<form name="fu">
<input name="nu" onblur="getval()">

</form

<hr>
<p id="showvalue">
This is the value of the field
</p>
<hr>
</div>
</body>
</html>

Please note that this will work on IE 5 and up and not NN,because 'innerText' property is not soported by NN.
You don't need to use CFML to display the value.

I hope this helps
