     ];

【问题讨论】：

不清楚：究竟需要删除什么？属性/对象？没有表现出任何努力。
需要删除包含空值的属性
edit 问题并添加您尝试解决此问题的代码。
如果{ "Id": "parent", "Function": "Project Management", "Phase": "" } 或{ "Id": "parent", "Function": "Project Management", "Phase": null} 怎么办？
@Mamun { "Id": "parent", "Function": "Project Management", "Phase": "" } or { "Id": "parent", "Function": "Project Management", "Phase": null} 对于这种情况我没有问题

【解决方案1】：

你可以这样做：

data = data.map(obj => Object.keys(obj).reduce((prev, prop) => {
  // you can check for '(Null)', null or for any different kind of value here
  if (obj[prop] != '(Null)') {
    prev[prop] = obj[prop]
  }
  return prev
}, {}))

【讨论】：

你也可以这样做：data.forEach((d, v)=> { for(x in d) { if(d[x] == "(Null)") { delete d[x] }; }});
