Question

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。

我做了一个小例子 - 它应该在你添加/删除/重命名节点时发出警报，但没有任何反应..

有谁知道为什么不解决这个问题？

jstree核心功能中没有callback属性。所以删除它：

    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');
        }
    }

您需要以这种方式绑定jstree对象之外的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');
});

JsTree contextmenu回调函数没有触发
