Our web application open a popup browser window contains a cutomized LiveCycle workspace from where the user submit a data form. I want to implement a feature that when the user close the browser window, a message box will pop up for user's confirmaiton (OK to close the window, Cancel to remain in the workspace window). Here is my code:
In javascript:
<script LANGUAGE="JavaScript">
window.onbeforeunload = confirmExit;
var needToConfirm = true;
var confirmMsg = "Are you sure you want to exit this page?"
function confirmExit() {
if (needToConfirm) {
alert("Event triggered!");
event.returnValue = confirmMsg;
//return confirmMsg;
}
}
function setNeedConfirm() {
needToConfirm = true;
}
function releaseNeedConfirm() {
needToConfirm = false;
}
</script>
In *.mxml:
flash.external.ExternalInterface.call("releaseNeedConfirm"); or flash.external.ExternalInterface.call("setNeedConfirm");
This approach works perfectly with IE, but for some reason it does not work with FireFox. I confirmed that the line alert("Event triggered!") is reached in FF, but no confirmation box is popped up.
Anyone can help me here?
Thanks
John
