I am looking into methods to inject javascript into any webpage loaded in the browser, so that I can traverse through the page’s DOM. I use JQUERY for my scripting needs.
Method should work in all browsers.
I tried using IFRAME and adding some html into it, but I cant. Please suggest some ways.
Try using Greasemonkey: http://www.greasespot.net/. You can use it to execute custom scripts on page load for any website you want. You can find some basic tutorials here: http://wiki.greasespot.net/Tutorials.
