Question

On a site that I’m building for someone, I am making most internal links use pushState since it is a faster user experience. I’m having a problem with getting the href attribute from an anchor <a> element that is loaded dynamically. People always tell me to use .on() rather than .live() because .live() is deprecated, but then I run into problems like this.

Here’s my code:

$('#artists').on('click', '.artist a', function(e) {
        SM.config.loader.show();
        var href = $(this).attr('href');
        SM.loadContent(href,'artist');
        history.pushState('', 'New URL: ' + href, href);
        e.preventDefault();
});

There is no href attribute being returned (obviously) so the URL is not changing.

Basically my question is how do I get the href attribute from the element in the second parameter of the on event?

This code is working for me: http://jsfiddle.net/NcZ22/2/

HTML

<div id="artists"></div>​

JS

//Bind an event
$('#artists').on('click', '.artist', function(e) {
        e.preventDefault();    
        var href = $(this).attr('href');
        console.log(href);
});​

//Add the element to the dom
$('<a />', {
    href: 'http://stackoverflow.com',
    text: 'SO',
    class: 'artist'
}).appendTo('#artists');

Also, make sure you are using jQuery 1.7+ You can read more about .on vs .delegate here http://api.jquery.com/delegate/

Simple comparison of syntax:

$(selector).live(events, data, handler);                // jQuery 1.3+
$(elements).delegate(selector, events, data, handler);  // jQuery 1.4.3+
$(elements).on(events, selector, data, handler);        // jQuery 1.7+
