ztree回显

$(document).ready(function(){ 

$.fn.zTree.init($("#treeDemo"), setting, zNodes);   //加载树 

zTree_Menu = $.fn.zTree.getZTreeObj("treeDemo");    // 获取 zTree 对象，是一个全局变量，用户可以随时使用此方法获取需要进行操作的 zTree 对象 



var name =window.dialogArguments.form.name.value; 
transformToArray
(zTree_Menu.getNodes());   

if (nodes.length>0) { 

for(var i=0;i

if(name.indexOf(nodes[i].name) >= 0){ 

nodes[i].checked = true; 

zTree_Menu.updateNode(nodes[i]); 

} 

} 

} 


});
 

 

 
还有一种比较笨的方法：
 
去DB中查询所有需要回显的Value，通过Ajax调用到前段之后，遍历所有的树节点，再遍历你查询到的Value，这样你就可以设置需要被回显的节点了，直接obj.checked=true
