前端--jstree--异步加载数据

• 利用回调来处理服务器返回的数据, 默认只能解析固定格式的返回值

<div class="">
    <div id="div-jstree">
        <div id="jstree">

        </div>
    </div>
</div>

<script>
    let jstree_ele = $("#jstree");
    jstree_ele.jstree({
        core: {
            check_callback: true,  
            data: function (node, callback) {
                $.ajax({
                    url: "/order-category/tree",
                    dataType: "json",
                    type: "POST",
                    data: {"id": node.id === '#' ? 0 : node.id},
                    success: function (data) {
                        let res = [];
                        if (isDataSuccess(data)) {
                            data = data.data;
                            for (let i = 0; i < data.length; i++) {
                                res.push({});
                                res[i].id = data[i].id;
                                res[i].text = data[i].name;
                                res[i].children = data[i].right - data[i].left > 1;
                                res[i].a_attr = {title: data[i].description};
                                res[i].icon = 'fa fa-bolt'
                            }
                        }
                        callback.call(this, res);
                    }
                })
            },
        },
    });
