Check (from bookmarklet) whether page is loaded?

I'm writing a bookmarklet javascript. The problem here is that it can be invoked by user before and after some page has finished loading. I want to ensure that the sript is run only after the page has finished loading. How to do that?

Solution

  • One way for checking if document has loaded, is to check the document.readyState property. IE, Firefox 3.6+, Webkit and Opera support it. 

    if (document.readyState === "complete") {
    // do sth
}

    Another thing is, if you want to wait for the document to load. In that case you have to listen to some events, like DOMContentLoaded on document, load on window or readyStateChange on document.
