jQuery $ .get和$ .parseXML获取Vimeo视频时长

Question

I need to get duration of specific video on vimeo before I've even loaded it player, so I see no other options rather than make an AJAX call and trying to get information about video. I've prepared the following structure:

$.get( "http://vimeo.com/api/v2/video/8957328.xml", function( data ) {
  var xmlDoc = $.parseXML(data),
  $duration = $(xmlDoc).find("title");
  $('div').html($duration.text());
});

As I can say, XML is parsed properly, but I'm not able to get final data, and I don't even have an idea why it's not working. Any help please?

jQuery itself parses the response for you, ie the data is already XML-parsed. Just pass the data to the jQuery constructor.

$.get( "http://vimeo.com/api/v2/video/8957328.xml", function( data ) {
  var $xmlDoc = $(data),
      $duration = $xmlDoc.find("title");
  $('div').html($duration.text());
});

Your code doesn't work as the passed value to the $.parseXML is not a string and the .parseXML method returns null .

jQuery.parseXML = function( data ) {
    var xml;
    if ( !data || typeof data !== "string" ) {
        return null;
    }
    // ...
};
