Check if jquery plugin is loaded

Question

How can I check if this jquery plugin backstrech was already loaded: http://cdnjs.cloudflare.com/ajax/libs/jquery-backstretch/2.0.4/jquery.backstretch.min.js

if($.fn.backstretch) is not working.

Answer 1

Looks like it works to me.

Fiddle:

backstretch_src = "http://cdnjs.cloudflare.com/ajax/libs/" +
                  "jquery-backstretch/2.0.4/jquery.backstretch.min.js";

$(function init() {
    updateStatus();
    $('head').append($('<script>').attr('src', backstretch_src));
    setTimeout(updateStatus, 1000);
});

function updateStatus() {
    $('#status').text($.fn.backstretch ? 'Loaded' : 'Not loaded');
}
