jQuery、layer实现弹出层的打开、关闭功能

$(".add_category,.update").click(function(){  
    //弹出框  
    var doMain = $('.domain_name').val();  
    layer.open({  
      shade: [0.5, '#000', false],  
      type: 2,  
      area: ['900px', '530px'],  
      fix: false, //不固定  
      maxmin: true,  
      title: ['添加或修改用户类型', false],  
      content: doMain+"/Stat/QueryUserCategoryForm.action?adminUserCategory.id="+$(this).val()  
    });  
  });  

<span style="color:#000099;">submitHandler: function (form){  
      $.post(  
        $('.domain_name').val()+"/Stat/AddOrUpdateUserCategory.action",  
        $(form).serialize(),  
        function(data){  
          var result = eval("("+data+")");  
          if(!result.status){  
            alert(result.message);  
          }else{  
            //添加数据成功，关闭弹出窗之前，刷新列表页面的数据  
            parent.window.location.href=$('.domain_name').val()+"/Stat/QueryUserCategoryListStat.action";  
            </span><span style="color:#ff6666;"> var index = parent.layer.getFrameIndex(window.name); //获取窗口索引  
            parent.layer.close(index); </span><span style="color:#000099;"> 
          }  
        }  
      );  
    } </span>
