jquery – Bootstrap选项卡在模式中不能通过AJAX工作

没有模态和ajax它工作正常.但是当我使用ajax在模态中加载选项卡式面板时,它不会选择选项卡窗格.

<!-- Nav tabs -->
<ul class="nav nav-tabs tabs-left">
    <li class="active tab-selection"><a data-toggle="tab" href="#financial">Financial</a></li>
    <li class="tab-selection"><a data-toggle="tab" href="#marketing">Marketing</a></li>
</ul>

<!-- Tab panes -->
<div class="tab-content">
  <div class="tab-pane active" id="financial">Financial Tab</div>
  <div class="tab-pane" id="marketing">Marketing Tab</div>      
</div>

AJAX

$.ajax({
        url : url,type : "POST",success:function(data){
            $(".modal-body").html(data);
        }
  });

我的模态

<div aria-hidden="true" aria-labelledby="myModalLabel" role="dialog" tabindex="-1" id="previewForm" class="modal fade">
  <div class="modal-dialog" style="width: 675px">
    <div class="modal-content">
    <div class="modal-header">
        <button data-dismiss="modal" class="close" type="button"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
        <h3 id="myModalLabel" class="modal-title">Preview</h3>
    </div>
        <div class="modal-body">
        </div>  
    </div>
 </div>
</div>

$(document).ready(function(){
    $(document).on("click",".modal-body li a",function()
    {
        tab = $(this).attr("href");
        $(".modal-body .tab-content div").each(function(){
            $(this).removeClass("active");
        });
        $(".modal-body .tab-content "+tab).addClass("active");
    });
});
