	<h3>setting & function 举例</h3>
	<h4>1. 设置异步获取节点的 URL 为 nodes.php</h4>
	<pre xmlns=""><code>var setting = {
	async: {
		enable: true,
		url: "nodes.php",
		autoParam: ["id", "name"]
	}
};
......</code></pre>
	<h4>2. 设置异步获取节点的 URL 为 function 动态获取</h4>
	<pre xmlns=""><code>function getAsyncUrl(treeId, treeNode) {
    return treeNode.isParent ? "nodes1.php" : "nodes2.php";
};
var setting = {
	async: {
		enable: true,
		url: getAsyncUrl,
		autoParam: ["id", "name"]
	}
};
......</code></pre>
