Change Title With Javascript

How can I modify the existing title to the document with Jquery as mouseover title chan开发者_C百科ge like that on facebook title link.

You don't need jQuery.

document.title = 'My new title here';

With javascript. jQuery won't help you here:

document.title = 'New Title';

You can insert that into a jQuery mouseover callback function if you want.

I'll extend on these other answers, this code should do it in entirety, just be sure to change the class in the selector, and the new Title Text.

(function(){
    var oldtitle;
    jQuery('a.yourlink').hover(
        function () {
           oldtitle = document.title;
           document.title = 'Your New Title';
        },
        function () {
            document.title = oldtitle;
        }
    );
})();

Here is a jsfiddle demo I made that changes the text of the object, rather than the window title: http://jsfiddle.net/MpZGf/1/

Try:

document.title = 'title';
