My colorbox parent page includes a TabContainer with various iFrames, and in the case of the second tab, a change is made to the database that requires updating a textbox on the parent window.
My colorbox parent page includes a TabContainer with various iFrames, and in the case of the second tab, a change is made to the database that requires updating a textbox on the parent window.
Regrettably, interacting beyond the boundaries of an iframe is not possible due to security concerns.
A potential solution is to modify the URL inside the iframe by adding a #anchor value or ?querystring, and then retrieve the updated URL from the parent element.
If you haven't already, give postMessage a try. It's a JavaScript API, but be aware of browser limitations.
The parent page can send messages like this:
var win = document.getElementById("iframe").contentWindow
win.postMessage(
"value",
"iframe-domain"
);
Meanwhile, the iframe page can receive and process these messages using the following code:
<script>
function listener(event){
if ( event.origin !== "[parent-page-domain]" )
return;
// Process event.data here
}
if (window.addEventListener){
addEventListener("message", listener, false)
} else {
attachEvent("onmessage", listener)
}
</script>
