Question

I’d like to write an extension that adds a div element to a page when a specific URL is loaded (e.g. when the url is http://www….&q=car&aq I’d like to have a div element containing “car” added to the webpage)

I’m already using addEventListener to check if a tab is open but I don’t know how to do it for a specific URL.

p.s I’m not asking you guys to do my homework, only some links to tutorials speaking of this kind of tricks or basic examples d.s

Answer 1

You can get the url using the command window.location so you can do something like

if (window.location.indexof("http://www.yoururl.com") != -1 && !$.browser.msie)
{
    //add a div to the dom here.

}

This line !$.browser.msie is actually jquery, and might not compile incase you are not including jquery libraries, it basically checks for the browser version is not IE.

You can remove this part — && !$.browser.msie — if you are not using jquery.
