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());   },
