jstree+；json-数组元素位于同一列表元素下

我是一名系统管理员，负责一些web开发工作，所以我没有大量的Javascript经验

现在我正在尝试使用jstree构建一个树，但是我的所有元素都在相同的

标记中结束。具体而言：

<ul>
    <li class="jstree-last jstree-leaf">
        <ins class="jstree-icon"> </ins>
        <a id="23" href="#">
            <ins class="jstree-icon"> </ins>
            a node
        </a>
        <a id="24" href="#">
        <ins class="jstree-icon"> </ins>
            another node
        </a>
    </li>
</ul>

被踢出的JSON如下所示：

$(document).ready(function() {
    $("#containersTypesTree").jstree({
        json_data : {
            ajax : {
                type : 'POST',
                url : "ajax.php",
                dataType : 'json',
                data : function() {
                    return {
                        action : 'getTree'
                    }
                },
            success : function (data) {
                console.log(data);
                return data;
            }
        }
    },
    plugins : [ "themes", "json_data" ]
    });

 });

{"data":[{"title":"a node","attr":{"id":"23"},"children":[]},{"title":"another node","attr":{"id":"24"},"children":[]}]}

**{"data":[{"title":"a node","attr":{"id":"23"},"children":[]},{"title":"another node","attr":{"id":"24"},"children":[]}]}**

弄明白了，JSON需要如下所示：

$(document).ready(function() {
    $("#containersTypesTree").jstree({
        json_data : {
            ajax : {
                type : 'POST',
                url : "ajax.php",
                dataType : 'json',
                data : function() {
                    return {
                        action : 'getTree'
                    }
                },
            success : function (data) {
                console.log(data);
                return data;
            }
        }
    },
    plugins : [ "themes", "json_data" ]
    });

 });

{"data":[{"title":"a node","attr":{"id":"23"},"children":[]},{"title":"another node","attr":{"id":"24"},"children":[]}]}

**{"data":[{"title":"a node","attr":{"id":"23"},"children":[]},{"title":"another node","attr":{"id":"24"},"children":[]}]}**
