我有一个如下的 JSON 数据

 [
  {
    "name": "car",
    "value": "",
    "children": [
      {
        "name": "v8_engine",
        "value": "",
        "children": [
          {
            "name": "cylinder-arrangement",
            "value": "",
            "children": [
              {
                "name": "type",
                "value": "string",
                "children": []
              },
              {
                "name": "max-elements",
                "value": "8",
                "children": []
              }
            ]
          }
        ]
      },
      {
        "name": "other-parts",
        "value": "",
        "children": [
          {
            "name": "per-cylinder-parts",
            "value": "",
            "children": [
              {
                "name": "piston-diameter",
                "value": "",
                "children": [
                  {
                    "name": "type",
                    "value": "uint32",
                    "children": []

                  },
                  {
                    "name": "range",
                    "value": "2000... 9000",
                    "children": []

                  }
                ]
              },
              {
                "name": "valves",
                "value": "",
                "children": [
                  {
                    "name": "number",
                    "value": "",
                    "children": []
                  },
                  {
                    "name": "position",
                    "value": "",
                    "children": []
                  }
                ]
              }
            ]
          }
        ]
      }
    ]
  }
]

我想解析每个元素及其各自的子元素，并将它们列为父子元素和它们的孙子，就像 GOJS 中的一棵简单的树。

我正在使用以下逻辑，但这只是解析和推送 go-js 模型中的节点数据和链接数据数组元素。

变量 i=0;

            function loop(a) {
                if(a.yang_type!='' && a.name!=''){
                  nodeDataArray.push({ key:i,Data: a.yang_type + " " + a.name, group: -1 });
                    console.log("Data:",a.yang_type);
                    linkDataArray.push({ from: i, to: i+1 });
              }

                if(a.name!='' && a.value!=''){
                    nodeDataArray.push({ key:i,Data: a.name + " " + a.value, group: -1 });
                    linkDataArray.push({ from: 0, to: i+1 });

                }
                //console.log(a.name);
                i=i+1;
                // process you data
                Array.isArray(a.children) && a.children.forEach(loop); // check and iterate children
                myDiagram.model = go.GraphLinksModel(nodeDataArray, linkDataArray);

            }

附件是我得到的输出，但孩子们很混乱。我在推动时错过了一些逻辑吗？在此处输入图像描述

我建议您使用 GoJS TreeModel而不是GraphLinksModel。http://gojs.net/latest/intro/usingModels.html

查看 DOM 树示例，http ://gojs.net/latest/samples/DOMTree.html 。特别注意traverseDom功能。TreeModel 期望有从子数据到父数据的引用。HTML DOM 与从 JSON 解析的数据一样，在父数据的 Array 中具有对子项的引用。该示例的traverseDom函数确保每个数据对象都有一个数字或字符串键，然后将子对象的parent属性分配给该键值。

然后，您可以将这些对象的 Array 用作TreeModel.nodeDataArray。
