JsTree 上下文菜单回调函数未触发

我正在使用 jstree 库。一个非常好的图书馆,但我遇到了一个问题。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,但没有任何反应..

有谁知道为什么不行,解决方案是什么?

你可以在网上看到工作-不工作的例子: http://www.leermetstrips.nl/Content/tree.htm

// TODO: this does not work, why?
callback: {
oncreate: function (NODE, REF_NODE, TYPE, TREE_OBJ, RB) {
alert('oncreate');
},
onrename: function (NODE, LANG, TREE_OBJ, RB) {
alert('onrename');

<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>
</body>

最佳答案

jstree 核心功能中没有callback 属性。所以删除这个:

    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');
}
}

你需要以这种方式在 jstree 对象之外绑定(bind) jstree 事件:

$('#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');
});
