How do I do something when user right click in a treeview's row?

I want to use localStorage to store large amount of data(like 800GB), according to http://arty.name/localstorage.html and also I'm using Firefox, I changed my localStorage size and also the cache size.

How to detect user's click on the link inside the iframe using JavaScript? You are able to check iframe load event onLoad="alert(this.contentWindow.location);" or on jquery: $('iframe#yourId').load(function() { alert("the iframe has been loaded"); }); Assuming you have an iframe with ID "myIframe", and the iframe comes from the same domain as the main document, the following will detect a click anywhere in the document.
