javascript - jstree 3.0.0 上下文菜单右键单击不起作用。显示 TypeError : vakata_context. element.html 不是函数

Question

我的代码正在渲染树、父子、子一切正常，但右键单击上下文菜单未显示。 Firebug 显示错误“TypeError:vakata_context.element.html 不是函数”。如果我删除上下文菜单插件，那么它会显示默认的浏览器右键单击选项。这是代码。

jsjQuery(document).ready(function () {
    $('#pages-wrapper').jstree({
        'core' : {
            callback:{
                onchange:function(node,tree){
                    document.location='pages.php?action=edit&id='
                    +node.id.replace(/.*_/,'');
                },
                onmove:function(node){
                    var p=$.tree.focused().parent(node);
                    var new_order=[],nodes=node.parentNode.childNodes;
                    for(var i=0;i<nodes.length;++i)
                        new_order.push(nodes[i].id.replace(/.*_/,''));
                    $.getJSON('/ww.admin/pages/move_page.php?id='

                        +'&order='+new_order);

一周前我遇到了同样的问题，添加以下 css 规则解决了我的问题:

.vakata-context { 
     z-index:999 !important; 
}
