jquery load（）禁用bootstrap下拉菜单

Question

当我使用jquery load（）在div中加载内容时，带有drowpdown菜单的bootstrap navbar停止工作。此外，导航栏背景颜色已更改为原始颜色，即css无法正常工作。我知道问题出在div id = tabs中，因为我删除它并且我再次正常工作。

$( document ).ready(function() {

  $('.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');
    });
