Question

我想在单击父节点后加载父节点的子节点。因为有很多孩子，这是保持高性能的唯一方法。

现在我得到了这个

$(function () {
    $.support.cors = true;
    $('#using_json').jstree({
        "plugins": ["themes", "json_data", "dnd", "wholerow"],
            'core': {
            'data': {
                'url': "http://localhost:56311/ProductRESTService.svc/GetCountryList",
                    'dataType': "json"
            }
        }
    });
});

这适用于第一级。现在我想从这个URL中获取孩子

“http://localhost:56311/ProductRESTService.svc/GetRegionList/（编号）”，

我不知道如何实现这个目标？

编辑：服务GetCountryList生成如下：

[{"id":"DE","parent":"#","state":"closed","text":"DE"},
{"id":"GBR","parent":"#","state":"closed","text":"GBR"},
{"id":"SE","parent":"#","state":"closed","text":"SE"}]

和GetRegionList

类似的东西：

[{"id":"SH","parent":"DE","state":"closed","text":"SH"},
{"id":"NRW","parent":"DE","state":"closed","text":"NRW"},
{"id":"LON","parent":"GBR","state":"closed","text":"LON"}]
