jsTree对象没有方法addBack [英] jsTree Object has no method addBack

问题描述

这是我对jsTree的实例化代码。

This is my instantiation code for the jsTree.

$("#folder_tree").jstree({
    "themes" : {
        "theme" : "default",
        "dots" : true,
        "icons" : true
    },
    "json_data" : {
        "ajax" : {
            "url" : "/portal/folders",
            "data" : function(n) {
                if ($(n[0]).find("a").attr("id")) {
                    console.log($(n[0]).find("a").attr("id").split('_')[1]);
                    return {
                        "id" : $(n[0]).find("a").attr("id").split('_')[1]
                    };
                }
                return { "id" : "0" };
            }
        }
    },
    "plugins" : [ "themes", "json_data", "ui", "contextmenu", "dnd", "search", "crrm" ]
}).bind("select_node.jstree", function(e,data) {
    console.log(data.rslt.obj.context.id);
});

它在第一次加载（0大小写）时正确加载数据，但是当我点击时扩展任何文件夹，它给我错误：

It loads the data correctly on the first load (the 0 case), but then when I click to expand any of the folders, it is giving me the error:

Uncaught TypeError: Object [object Object] has no method 'addBack' 

即使扩展节点的正确id被记录到控制台并且ajax请求是正确地对服务器。另请注意，我必须使用相当可怕的kludge来查找元素的id，因为在尝试访问时，记录的代码只会产生错误（我使用与文档相同的jsTree版本） n.attr（ ID）。另外，在下绑定（select_node... 我必须使用未记录的函数再次查找id。经过数小时的故障排除后，我仍然感到困惑，但有些东西显然无法正常运行。

Even though the correct id of the expanded node is being logged to the console and the ajax request is being made to the server correctly. Notice also that I have to use a fairly horrific kludge to find the id of the element due to the fact that the documented code produces nothing but errors for me (and I am using the same version of jsTree as the documentation) when trying to access n.attr("id"). Plus, under bind("select_node"... I have to use a non-documented function to find the id again. After hours of troubleshooting, I'm still completely baffled, but something is clearly not operating correctly.

推荐答案

确保使用的是jQuery 1.8或更高版本。直到那时才添加addBack 。

Make sure you are using jQuery 1.8 or later. addBack wasn't added until then.
