EasyUI的tree展开所有的节点或者根据特殊的条件控制展示指定的节点

$(function(){
 $('#t_funinfo_tree').tree({
  checkbox: true,
  url:"<%=basePath %>/getT_FuninfoTree.do?pid='00000'",
  onBeforeExpand:function(node){
      $('#t_funinfo_tree').tree('options').url="<%=basePath %>/getT_FuninfoTree.do?pid="+node.id;
  },
  lines:true,
  onLoadSuccess:function(node,data){
      var t = $(this);
      if(data){
          $(data).each(function(index,d){
              if(this.state == 'closed'){
                 t.tree('expandAll');
              }
          });
      }
  }
 });
})

onLoadSuccess:function(node,data){
    /*if(node!=null && (node.attributes.parentid=='1'||node.attributes.parentid=='-1')){
        $("#mainFra",parent.document.body).attr("src",'<s:url value="/bankcredit/bankcreditAction!browseBankcreditList.action"/>?parentId='+node.attributes.serialnum);
    }else{
        return;
    }*/
    //根据bankName进行判断是否展开菜单
    if(data[0].bankname=="放款单位"||data[0].bankname=="银行"||data[0].bankname=="P2P"){
         var t = $(this);
         if(data){
            $(data).each(function(index,d){
                if(this.state == 'closed'){
                   t.tree('expandAll');
                }
            });
        }
    }
},
