我用的异步加载，我想试验后台传到前台的数据是否能被自动解析成json格式
但是，运行后，树桩列表不显示，我就想用回调函数看一下状态，
如果成功加载：alert出 msg
如果失败：alert一些信息出来
可是不管是否成功，都不触发回调函数，
以下后台代码是演示出的数据，可以在页面中正常显示树，但是！asyncSuccess 回调函数没有被触发，怎么回事？不是成功了嘛？
java Demo代码
public void getSynCheckboxTree(){
PrintWriter out = null;
String zNodesOne = "[{name:\"100个节点\", id:\"1\", count:1, times:1,isParent:true},"
+"{name:\"500个节点\", id:\"2\", count:500, times:1,isParent:false}," +
"{name:\"1000个节点\",id:\"3\", count:1000, times:1,isParent:true}]";
try {
out = new PrintWriter(this.response.getWriter());
out.print(zNodesOne); out.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
out.close();
}

你好， 请你再仔细看看 API 文档 ，关于回调函数是配置在哪里的？ 比如 asyncSuccess，应该是 setting.callback.asyncSuccess
