Trigger a function from pop up window and arguments question...

S

Sally B.

Hi,

I have a main page that opens a pop up window when the user clicks a
link. The pop up window is a menu and when the user clicks the item, it
populates a form input element on the 'parent' window.

My question is: this new populated form element is the value that I use
to change a style.

onchange does not watch this form element because of getelementbyid, so
it doesn't trigger the function needed to change the style. onchange
works fine if I just manually input a value into the text box.

Any other way to fire the function off when the user picks their
selection from the pop-up window? I was thinking I could use
window.opener.function()? But how do I pass the form from the parent
window? From the pop up window, I don't use this.form, what do I
use?something like window.opener.form[0] ?

thks

Input value into the text box by code and then explicitly call function
which you use as onchange event handler.
window? From the pop up window, I don't use this.form, what do I
use?something like window.opener.form[0] ?

opener is ahother window and it has no "form" property, use
opener.document.form[0].

But better you can define a function in the main window and call it
from a popup window.
e.g.

main window

<html>
<body>
<script type=text/javascript>
function foo(val){
document.getElementById("tb1").value = val;
tb1Changed(val);
}
function tb1Changed(val){
alert("textbox value: " + val);
}
</script>
<input type=button
onclick="window.open('2.htm','popup','height=300,width=300');"
value="Open popup window">
<input type="text" id="tb1" onchange="tb1Changed(this.value)">
</body>
</html>


popup window

<html>
<body>
<input type=button onclick="opener.foo('test');" value="Change main
window">
</body>
</html>
