json to nested ul li jquery / javascript

Question

我使用拖放构建器的JavaScript创建动态JSON，现在我无法将JSON转换为嵌套的UL LI。JSON在下面。

[
  {
    "id": "11",
    "name": "BALANCE"
  },
  {
    "id": "p1",
    "name": "Conditions",
    "nodes": [
      {
        "id": "p1-13",
        "name": "SPINAL CORD INJURY",
        "nodes": [
          {
            "id": "p1-13-12",
            "name": "STROKE",
            "nodes": [
              {
                "id": "p1-13-12-17",
                "name": "REACHING"
              }
            ]
          }
        ]
      }
    ]
  },
  {
    "id": "p1-16",
    "name": "STRETCHES"
  },
  {
    "id": "p1-11",
    "name": "BALANCE"
  }
]

您可以创建一个function并在项目中有nodes时递归致电。

var json = [{"id":"11","name":"BALANCE"},{"id":"p1","name":"Conditions","nodes":[{"id":"p1-13","name":"SPINAL CORD INJURY","nodes":[{"id":"p1-13-12","name":"STROKE","nodes":[{"id":"p1-13-12-17","name":"REACHING"}]}]}]},{"id":"p1-16","name":"STRETCHES"},{"id":"p1-11","name":"BALANCE"}];
function createUl(data, $elm) {
  data.forEach(function(item) {
    var $li = $('<li><span>' + item.name + '</span></li>');
    $elm.append($li);
    if (item.nodes) {
      var $ul = $('<ul></ul>');
      $li.append($ul);
      createUl(item.nodes, $ul);
    }
  });
};
createUl(json, $('ul'));
