zTree获取选中节点的值并赋给隐藏域

function onCheck(e, treeId, treeNode) {

var zTree = $.fn.zTree.getZTreeObj("testtree"),

nodes = zTree.getCheckedNodes(true),

v = "";

for (var i=0, l=nodes.length; i<l; i++) {

v += nodes[i].name + ",";

alert(nodes[i].id); //获取选中节点的id值

document.getElementById('test').value=nodes[i].id;

}

if (v.length > 0 ) v = v.substring(0, v.length-1);

var cityObj = $("#citySel");

cityObj.attr("value", v);

}
