Auto activate function

cumap · May 14, 2009

hi all,

This is a task I need to do.
- a operation page that with all functionalities.
- a popup where user will fill in or select choices.
- after make all selections and have all info filled out, popup page will automatically close when submitted, and the opener (operation page) receive the form's info and automatically activate a specific function to process them.

The key here is the last step: automatically activate the function. Is there is way in js to do that?

I tried to move/copy those functions to the popup page and executed them when submitted, but the functions didn't work correctly due to some related data are collecting in the operation page.

Thanks!

Two ways:

1.
- On the opener, place a hidden text box and set an onblur event to execute a function:

<input type="hidden" id="myTbx" onblur="doIt();" />
- in the popup, create an onunload funtion that focuses on the parent text box and then use immediately blur it

Code:

<script language="javascript">
function foo() {
parent.document.getElementById("myTbx").focus();
parent.document.getElementById("myTbx").blur();
}
</script>
<body onunload = "foo();">
...
</body>

2.
- assign the pop up to an obj:

var myPopup = window.open(...)

- create a recurive function in your parent window that kicks out once the pop up is closed

Code:

function foo() {
 if myPopup.closed {
   doIt();
 } else { foo(); }
}

the second option could eat up a lot of processing power on the client so it is not recommended unless the pop up is closed within a couple of seconds

GOOGLE is a great resource to find answers to questions like "how do i..."

If you don't know exaclty what you want to do or what to search one, try Google Suggest:

I have recently been semi-converted to ensuring all my code (well most of it) works in both javascript and non-javasc
