Javascript 从json获取分层数据

我想写一个函数，它接受一个键并递归地获取它的所有子项

var oTeamHierarchyJson = [
            {
                "Key": "10011",
                "Name": "A",                
                "Job Title": "VP",                
                "children": "C",
                "Parent": "1000",
                "Level": "1"
            },
            {
                "Key": "10012",
                "Name": "B",                
                "Job Title": "VP",                
                "children": "D",
                "Parent": "1001",
                "Level": "1"
            },
            {
                "Key": "10013",
                "Name": "C",               
                "Job Title": "GM",                
                "children": "E",
                "Parent": "10011",
                "Level": "2"
            },
            {
                "Key": "10014",
                "Name": "D",
                "Job Title": "MP",                
                "children": "F",
                "Parent": "10013",
                "Level": "3"
            }
        ];

function filterJSONData(currentKey) {
      //return all children recursively
}

对于10011-return 10013、10014

数据结构只保存父关系，而不保存子关系，这实际上不适合遍历。有两种方法可以避免这一缺点：

处理数组，使每个注释都引用其所有子项

引入一个helper函数，该函数返回节点的所有子节点

---

之后，递归地查找给定节点的所有后续节点就容易多了。

function filterJSONData(currentKey) {

您可以从平面数据列表构建树。下面的代码递归地添加一个属性子节点，并用每个节点的子节点填充它。

var oTeamHierarchyJson = [
            {
                "Key": "10011",
                "Name": "A",                
                "Job Title": "VP",                
                "children": "C",
                "Parent": "1000",
                "Level": "1"
            },
            {
                "Key": "10012",
                "Name": "B",                
                "Job Title": "VP",                
                "children": "D",
                "Parent": "1001",
                "Level": "1"
            },
            {
                "Key": "10013",
                "Name": "C",               
                "Job Title": "GM",                
                "children": "E",
                "Parent": "10011",
                "Level": "2"
            },
            {
                "Key": "10014",
                "Name": "D",
                "Job Title": "MP",                
                "children": "F",
                "Parent": "10013",
                "Level": "3"
            }
        ];

function filterJSONData(currentKey) {
      //return all children recursively
}

看

buildTree=函数（数组，节点）{
//获取节点
var节点=null；
对于（var i=0；i，您可以从平面数据列表构建一棵树。
