这是详细情况

1. 我正在使用jquery处理一些动态的东西
2. 第一页包含2个div，一个为id=menu，另一个为id=subpage1，
3. 我单击#menu中的一个链接，将页面加载到#subpage1.
4. 再次有一个页面包含2个divs #menu2和#subpage2
5. 在这里，我制作了一个脚本，该脚本通过仅使用一个参数....这是列表菜单的ID来自动将页面加载到#subpage2.

6. 此脚本是..

1. i'm working on some dynamic stuff using jquery
2. the first page contains 2 divs, ones id=menu and others id=subpage1,
3. i click on one link from #menu, a page is loaded into #subpage1.
4. there is again a page with 2 divs #menu2 and #subpage2
5. here i made a script that loads pages automatically to #subpage2 by taking only 1 parameter ....which is id of a listmenu.

6. this script is..

 $("#menu2 li").click(function(){
     $("#subpage2").load($(this).attr('page_link'));
   }
 }).filter('#menu2 li:eq(0)').click();
 

    $("#bottom_bar #backbtn").click(function(){
    var $bottomLineBtn = $(this);
    $bottomLineBtn.parent().parent().parent().find('#menu2 li:eq(1)').click();
    })

 myfun(tab_index, acc_id){
        alert(tab_index +" | +" acc_id);
    }
