在jquery.simple.tree.js里找到这个drag:ture.改为false  就可以了

TREE.option = {
   drag:  false,//控制拖拽
   animate: false,
   autoclose: false,
   speed:  'fast',
   afterAjax: false,
   afterMove: false,
   afterClick: false,
   afterDblClick: false,
   // added by Erik Dohmen (2BinBusiness.nl) to make context menu cliks available
   afterContextMenu: false,
   docToFolderConvert:false
  };

 

 

simpleTree单击控制目录的展开和关闭

  afterClick:function(node){
   var obj = $('span:first',node).parent();
   obj.parent().find("li[class='folder-open']").each(function(){
    $(this).attr("class","folder-close");
    $(this).find("ul").hide();
   });
   if(obj.attr("class")=="folder-close"){
    obj.attr("class","folder-open");
    obj.find("ul").show();
   }else{
    obj.attr("class","folder-close");
    obj.find("ul").hide();
   }
   //alert("text-"+$('span:first',node).text());
  },
