var closableTab = {
    //添加tab
addTab:function(tabItem){ //tabItem = {id,name,url,closable}
 
var id = "tab_seed_" + tabItem.id;
var container ="tab_container_" + tabItem.id;
 
$("li[id^=tab_seed_]").removeClass("active");
$("div[id^=tab_container_]").removeClass("active");
 
if(!$('#'+id)[0]){
var li_tab = &#39;<li role="presentation" class="" id="&#39;+id+&#39;"><a href="#&#39;+container+&#39;"  role="tab" data-toggle="tab" style="position: relative;padding:2px 20px 2px 15px">&#39;+tabItem.name;
if(tabItem.closable){
li_tab = li_tab + &#39;<i class="glyphicon glyphicon-remove small" tabclose="&#39;+id+&#39;" style="position: absolute;right:4px;top: 4px;"  οnclick="closableTab.closeTab(this)"></i></a></li> &#39;;
}else{
li_tab = li_tab + &#39;</a></li>&#39;;
}
var tabpanel = &#39;<div role="tabpanel" class="tab-pane" id="&#39;+container+&#39;" style="width: 100%;">&#39;+
      &#39;正在加载...&#39;+
       &#39;</div>&#39;;
 
 
$(&#39;.nav-tabs&#39;).append(li_tab);
$(&#39;.tab-content&#39;).append(tabpanel);
$(&#39;#&#39;+container).load(tabItem.url,function(response,status,xhr){
if(status==&#39;error&#39;){//status的值为success和error，如果error则显示一个错误页面
$(this).html(response);
}
});
}
$("#"+id).addClass("active");
$("#"+container).addClass("active");
},
 
//关闭tab
closeTab:function(item){
var val = $(item).attr(&#39;tabclose&#39;);
var containerId = "tab_container_"+val.substring(9);
       
       if($(&#39;#&#39;+containerId).hasClass(&#39;active&#39;)){
       $(&#39;#&#39;+val).prev().addClass(&#39;active&#39;);
       $(&#39;#&#39;+containerId).prev().addClass(&#39;active&#39;);
       }
 
 
$("#"+val).remove();
$("#"+containerId).remove();
}
}
