Popup box without reload when activated from a different url.

[Kaster]

I am using the script below on several webpages, to pop up a window where people can order some things. It works well when shifting forth and back between the same page from where it is activated.
But when it is reactivated from another page on the website the popup is reloaded and things written here dissapear. Is there a way to avoid the popup to reload and only come into focus when clicked from another page?

[  <script type="text/javascript">
//<![CDATA[var foo=null; function focusfoo(){if (foo&&!foo.closed) foo.focus();}
function blurfoo(){ if (foo&&!foo.closed) foo.blur();} //]]>
</script>
<a href="javascript:void(0)" onclick="foo=window.open('popuppage.htm','win4','width=700,height=460,top=11,left=0,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes');return false" onfocus="foo;" onmouseover="focusfoo();"></a>  ]
 

Thank you.

When you change the page, the reference to the pop-up window will be lost. You can use the pop-up window to re-establish it by using window.opener to refer to its parent window.

Can´t make it work. How should I put it? Tried ....

<a href="javascript:void(0)" onclick="foo=window.open('popuppage.htm','win4','width=700,height=460,top=11,left=0,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes');return false" window.opener="parent();" onmouseover="focusfoo();"></a>

....and...

<a href="javascript:void(0)" onclick="foo=window.open('popuppage.htm','win4',window.opener='parent','width=700,height=460,top=11,left=0,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes');return false" onmouseover="focusfoo();"></a>

......but they still reload the popup box.
Thanks again.

window.opener would be used from the popup window, not from the parent. One idea is to periodically check the parent for a reference to the popup using setInterval. If it doesn't exist, reset the variable foo to the popup window.

I don´t know how to write this Acoder. I have rewritten the script to look like this:

<script type="text/javascript">
//<![CDATA[
function pop() { 
if (!foo) 
foo=window.open('boks.htm','win4','width=700,height=460,top=11,left=300,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes'); 
else foo.focus(); 
} 
var foo=null; function focusfoo(){if (foo&&!foo.closed) foo.focus();}
function blurfoo(){ if (foo&&!foo.closed) foo.blur();} 
//]]></script>
 
<a href="boks.htm" target="boks" 
onclick="pop();return false" onMouseOver="focusfoo()";>Stil spørgsmål til os.</a>

You can see it in function http://es-masseovne.dk/side1.htm

When clicked and reclicked from the same page, it does not reload the pop. But when the same link is clicked from other page the popupform is still reloaded (reset).

You need to add code in the pop-up window, not the parent window to allow the parent to re-establish the reference.

For example:

setInterval(testFoo,5000); // every five seconds
function testFoo() {
    if (!window.opener.foo) {
        window.opener.foo = self;
    }
}

Haven't tested, but just an idea.

Acoder you rock!
It did the trick. Thanks a lot, I appreciate your great assitance.

You're welcome. Glad it worked.

PS. You may also want to add a check for window.opener in case the parent window has been closed (unless you close the child window when the parent is closed).
