var setting = { check: { enable: true }, async: { enable: true, type : "post", url: "/jyw/sysadmin/index.php?r=administrativedivision/getSubordinate", autoParam: ["id"] } };
我这样设置了，但是点击节点的链接没有反应，通过firebugs看没有发出请求，请问是怎么回事。。

异步加载不是点击节点链接触发的，而是点击 +/- 号触发的， 如果希望点击节点就异步加载，那么请参考Demo：http://www.ztree.me/v3/demo.php#_502

点击+号请求到服务器端的方法了，这是返回的数据，但是页面上没有显示出子节点来。。还需要做些什么啊。。[{"id":"130100","pId":"130000","name":"\u77f3\u5bb6\u5e84\u5e02","isParent":true},{"id":"130200","pId":"130000","name":"\u5510\u5c71\u5e02","isParent":true},{"id":"130300","pId":"130000","name":"\u79e6\u7687\u5c9b\u5e02","isParent":true},{"id":"130400","pId":"130000","name":"\u90af\u90f8\u5e02","isParent":true},{"id":"130500","pId":"130000","name":"\u90a2\u53f0\u5e02","isParent":true},{"id":"130600","pId":"130000","name":"\u4fdd\u5b9a\u5e02","isParent":true},{"id":"130700","pId":"130000","name":"\u5f20\u5bb6\u53e3\u5e02","isParent":true},{"id":"130800","pId":"130000","name":"\u627f\u5fb7\u5e02","isParent":true},{"id":"130900","pId":"130000","name":"\u6ca7\u5dde\u5e02","isParent":true},{"id":"131000","pId":"130000","name":"\u5eca\u574a\u5e02","isParent":true},{"id":"131100","pId":"130000","name":"\u8861\u6c34\u5e02","isParent":true}]

好吧，知道了。。方法里不能return，要直接echo。。
