我正在使用jstree库。一个非常好的图书馆，但是我遇到了一个问题。上下文菜单的回调不起作用。
我做了一个小的工作示例-当您添加/删除/重命名节点时，它应该发出警报，但是什么也没有发生。
有谁知道为什么不这样做，解决方案是什么？
您可以在线查看无法正常工作的示例：http : //www.leermetstrips.nl/Content/tree.htm

<h3>JS tree example</h3>
<p>When adding, or deleting new nodes, there should be an alert. But there is none. Why?</p>
<div id="tree" style="border:1px solid;"></div>
<p>Click on the tree with your right mouse button to add, rename or delete NEW tree nodes.</p>

callbackjstree核心功能没有属性。因此，删除此：
callback: {
oncreate: function (NODE, REF_NODE, TYPE, TREE_OBJ, RB) {
alert('oncreate');
},
onrename: function (NODE, LANG, TREE_OBJ, RB) {
alert('onrename');
},
ondelete: function (NODE, TREE_OBJ, RB) {
alert('ondelete');
}
}
您需要通过以下方式将jstree事件绑定到jstree对象之外：
$('#tree').bind('create.jstree',function (node, ref) {
alert('oncreate');
});
$('#tree').bind('rename.jstree',function (node, ref) {
alert('onrename');
});
$('#tree').bind('remove.jstree',function (node, ref) {
alert('ondelete');
});
