I am trying to click a sidebar Menu (div #cssmenu) element and if so it loads content into a div (#tabs). The problem is that the content has a load in it's structure (so it does a load of load) and i think it is the reason i get this warning and error :
Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience.
Undefined is not a function on line pane.tab('show'); 
This just disable all my dropdown menus in #cssmenu. Thank any help !
$( document ).ready(function() {
$('#tab_quick').load($('#tabs .active a').attr("data-url"),function(result){
  $('.active a').tab('show');
});
$('#tabs a').click(function (e) {
    e.preventDefault();
    var url = $(this).attr("data-url");
    var href = this.hash; 
    var pane = $(this);
    // ajax load from data-url
    $(href).load(url,function(result){      
        pane.tab('show');
    });
  });
});
$( document ).ready(function() {    
    $('#cssmenu a').click(function (e) {
        e.preventDefault();
        var url = $(this).data('url'); 
        var pane = $(this);
        // ajax load from data-url
        $('#tabs').load(url, function(result){ // load the content directly to #tabs     
            pane.tab('show'); // display the tab
        });   
    });
});
