detecting a form

Hello !

I want to detect if a form is in a document.
In facts, I have a field that displays the value of another field in a form that's in another page (I'm using frames, one page does refresh every 2sec, one never refresh but displays the content of the refreshed one)

the window.onerror method tells me 'not implemented' ...

thanks guys.

try something like :

<html>
<body>
<form name="myForm">
<input type="text" size="10" name="fieldOne" value="100">
</form>
<script language="javascript">
if (document.myForm)
{
alert(document.myForm.fieldOne.value);
}
</script>
</body>

If the field is in another frame you will need to access it via something like :

parent.main.myForm.fieldOne.value

if you are accessing the value of fieldOne in the form myForm which is in the frame called main which is defined in the same frameset as the current frame.
</html>
