jQuery load page only once on tab click

问题

I have a page with some tabs on it and upon clicking on certain tabs, other pages are loaded dynamically. The only problem is that these pages load every time the tabs are clicked on. How do I make them load only once, at the first click?

The code that I use is this:

$(document).ready(function(){
    $(".tab-content").hide();
    $("#one").show();

    $("a.tab-name").click(function(){
        $(".tab-name-active").removeClass("tab-name-active");
        $(this).addClass("tab-name-active");
        $(".tab-content").fadeOut();
        var content_show=$(this).attr("title");

        if (content_show === 'three') {
            $("#"+content_show).load('new-page.php', function() {
                $("#sorttable").tablesorter({
                    headers: {0: {sorter: false}}
                });
            });
        }
        else if (content_show === 'four') {
            $("#"+content_show).load('new-page-2.php');
        }

        $("#"+content_show).delay(100).fadeIn('slow');

        return false;
    });
});

Thanks!

use .data() to save a boolean value.

$(document).ready(function(){
    $(".tab-content").hide();
    $("#one").show();

    $("a.tab-name").data('loaded',false).click(function(){
        var $this = $(this);
        $(".tab-name-active").removeClass("tab-name-active");
        $this.addClass("tab-name-active");
        $(".tab-content").fadeOut();
        var content_show= this.title;

        if (! $this.data('loaded')) {

          if (content_show === 'three') {
            $("#"+content_show).load('new-page.php', function() {
                $("#sorttable").tablesorter({
                    headers: {0: {sorter: false}}
                });
                $this.data('loaded',true);
            });
          }
          else if (content_show === 'four') {
            $("#"+content_show).load('new-page-2.php', function(){
                $this.data('loaded',true);
            });
          }

        } 

        $("#"+content_show).delay(100).fadeIn('slow');

        return false;
    });
});

I just did a feature like this yesterday. The way I did it though was add a "still_loading" class in an arbitrary div(say your container div) then when the tab finally loads, remove that class again.
