您没有将 jquery 库加载到您的 fiddle 中。

在这里查看它的工作情况 FIDDLE

$(function() {
    $("#block_2 div,#block_3 div,#block_4 div").hide();

    $("#block_1 div").click(function(){
        $("#block_2 div,#block_3 div,#block_4 div").hide();
        $("#block_2 div."+$(this).attr('id')).show("fast");

        $("#block_2 div").click(function(){
            $("#block_3 div,#block_4 div").hide();
            $("#block_3 div."+$(this).attr('id')).show("fast");

            $("#block_3 div").click(function(){
                $("#block_4 div").hide();
                $("#block_4 div."+$(this).attr('id')).show("fast");
            })
        });
    });
});
