下面是获得他的div的id两种方法，虽然第一个方法复杂，但是可以很好研究了tab的js

//增加新的考评选项
 //urlstr:要处理的URL地址
  addAppraisalModel:function(urlstr){
  
  //打开一个新的tab。其父节点是一个id为'appraisalList'的DIV，
  tabview.createNewTab('appraisalList',appraisalResource.tabModelName0,'',urlstr,true);
 //获得父DIV节点
  var pdiv = document.getElementById('appraisalList');
    //获得父节点的最后一个孩子，就是最新打开的tab。  
  var lastDivNode = pdiv.lastChild;
    //我在主页面放了一个隐藏的<input>，用来存放最新打开的tab DIV的id。以便以后对此DIV进行刷新  
  var hiddenIndex = document.getElementById("tabIndex");
   if(hiddenIndex != null){
    hiddenIndex.value = lastDivNode.id;
   }
 },

 

第二种方法，比较简单。就是把要加载的页面放到指定的div中。这样div的id就可以我们自己来指定了。不用在动态的获得了
