onUnload event for a side bar

[rajumon]

Hi,
I have a sidebar application, which is used for web annotation.
I added the following code for handling the sidebar onload and onunload. When I press the close button, the onUnload event is called. Actually I need a confirm box, containing the text “Do you want to close the side bar?”. Even when I press the cancel, the side bar is closed. How can I set “Ok” and “Cancel” options to the window.onUnload event? Is this only applicable for websites? Or Does Sidebar have special event handling for close?

Code:

onLoad: function(e) {
alert(‘load’);
},
onUnload: function(e) {
if(confirm(“Do you want to close the sidebar?”))
{
alert(‘closing’);return true;
}
else
{
alert(‘continue’);return false;
}

}
}

window.addEventListener(“load”, function(e) { skratch.onLoad(e); }, false);
window.addEventListener(“unload”, function(e) { skratch.onUnload(e); }, false);

Hey have You check the Last Two Lines , Check the true False Parameter , shouldnt they should be opposite

window.addEventListener(“load”, function(e) { skratch.onLoad(e); }, false);
window.addEventListener(“unload”, function(e) { skratch.onUnload(e); }, false);

Well , i dont have any idea , but just give it a try

I will explain the actual work flow. Actually My website “http:/localhost” is set as the sidebar url of the sidebar. So when taking the sidebar from the view=>Sidebar menu, and the sidebar loads. On page loading, the datas from the sidebar will get into the “http:/localhost”. Actually these are done in the website code. like “window.addEventListener(”myevent", myeventListener, false, true);"
Now I need to check the sidebar close, whether any pop up window is opened or not from the sidebar. If so, I need to catch the close event and need to return false.
When pressing the close button, the page inside the sidebar url will be onunload,,,and even when we put a confirmation into this condition,,the sidebar closes in both cases.
