这里记录一下zTree的check的使用

下面介绍一下我的用法，因为我的需求比较特殊，一个子节点有可能在不同的根目录下，加载时用的方法如下：看图即可（北桥中学在不同的目录下）
function PaperPublish(id, name) {
//获得数据库中已选择的班级动态绑定到tree上
$.ajax({
type: "POST",
url: "/eqes_Questionnaire/Manager/GetQueRangeTree.ashx?op=inittree",
data: { scid: id },
cache: false,
success: function(result) {
//处理所有的返回值
var treeObj = $.fn.zTree.getZTreeObj("treeDemo");
treeObj.checkAllNodes(false);
var strs = new Array(); //定义一数组
strs = result.split(","); //字符分割
for (i = 0; i < strs.length; i++) {
if (strs[i] != "") {
var strche = strs[i].split("-");
//这里获得需要动态选择的节点以及该节点的根节点（我这里子节点可以在不同的根节点中）
if (strche[1] != null) {
//这里获得子节点所在的根目录节点
var nodell = treeObj.getNodeByParam("id", strche[1], null)
//在改目录节点下搜索符合条件的节点
treeObj.checkNode(treeObj.getNodeByParam("id", strche[0], nodell), true, true);
} else {
treeObj.checkNode(treeObj.getNodeByParam("id", strche[0], null), true, true);
}
}
}
},
error: function() { alert("请求失败"); }
});
}再次记录一下
