Set zTree asynchronous loading mode on/off.
Default: false
true - turn on asynchronous loading mode
false - turn off asynchronous loading mode
If set it is true, you must set other attributes in setting.async
If you don't pass the 'treeNodes' parameter when you initialize zTree, the root nodes will be retrieved using ajax.
var setting = {
async: {
enable: true,
url: "http://host/getNode.php",
autoParam: ["id", "name"]
}
};
