How to bind to jquery-mobile pagebeforeload event?

问题

I'm getting desperate trying to get the jQuery mobile pagebeforeload event to fire. This just does nothing:

 $(document).on("pagebeforeload", function( e, data ) {
        console.log("hello");
    });

According to the JQM docs, the syntax is correct. Still, nothing happens. Can anybody tell me why that is?

Make sure you're including preventDefault(); Otherwise, it'll just merrily continue loading.

Docs: http://jquerymobile.com/demos/1.1.0/docs/api/events.html

$( document ).bind( "pagebeforeload", function( event, data ){

    // Let the framework know we're going to handle the load.

    event.preventDefault();

    // ... load the document then insert it into the DOM ...
    // at some point, either in this callback, or through
    // some other async means, call resolve, passing in
    // the following args, plus a jQuery collection object
    // containing the DOM element for the page.

    data.deferred.resolve( data.absUrl, data.options, page );

});

Your code worked for me exactly as it is.

Be sure to note that this will only work if you are loading a separate page. It will not work for internally linked pages because it is not actually loading a page.
