如何从对象数组创建树视图表- Javascript

// 定义对象数组
var data = [
  { id: 1, name: '节点1', parentId: null },
  { id: 2, name: '节点2', parentId: 1 },
  { id: 3, name: '节点3', parentId: 1 },
  { id: 4, name: '节点4', parentId: 2 },
  { id: 5, name: '节点5', parentId: 2 },
  { id: 6, name: '节点6', parentId: 3 },
];

// 创建树视图表
function createTreeView(data, parentId = null) {
  var tree = [];
  for (var i = 0; i < data.length; i++) {
    if (data[i].parentId === parentId) {
      var children = createTreeView(data, data[i].id);
      if (children.length > 0) {
        data[i].children = children;
      }
      tree.push(data[i]);
    }
  }
  return tree;
}

// 调用函数创建树视图表
var treeView = createTreeView(data);

// 打印树视图表
console.log(treeView);
