我正在尝试让jsTree处理子节点的按需加载.我的代码是这样的:

jQuery('#introspection_tree').jstree({ 
        "json_data" : {
            "ajax" : {
                url : "http://localhost/introspection/introspection/product"
            }
    },
    "plugins" : [ "themes", "json_data", "ui" ]
    });

从通话中返回的json是

[
  {
    "data": "Kit 1",
    "attr": {
      "id": "1"
    },
    "children": [
      [
        {
          "data": "Hardware",
          "attr": {
            "id": "2"
          },
          "children": [

          ]
        }
      ],
      [
        {
          "data": "Software",
          "attr": {
            "id": "3"
          },
          "children": [

          ]
        }
      ]
    ]
  }
  .....
]

每个元素都可能有很多孩子,树会很大.目前这是一次加载整个树,这可能需要一些时间.当用户打开子节点时,如何实现按需加载子节点,我该怎么办？

提前致谢.
