javascript - 如何通过关键字删除 json 数组中的所有对象

Question

我有这样的 json:

json = [ 
   { 
      "value1":"3863",
      "value2":"4567"
   },
   { 
      "value1":"4456",
      "value2":"87687"
   },
   { 
      "value1":"98494",
      "value2":"4534"
   },   
]

我需要的是删除 value2 以便 json 看起来像:

json = [ 
   { 
      "value1":"3863"
   },
   { 
      "value1":"4456"
   },
   { 
      "value1":"98494"
   },   
]

我试过用

for(var i = 0; i < json.length; i++)
{    
  delete json["value2"];   
}

但它不起作用。

有什么办法吗？

Answer 1

const json = [ 
   { 
      "value1":"3863",
      "value2":"4567"
   },
   { 
      "value1":"4456",
      "value2":"87687"
   },
   { 
      "value1":"98494",
      "value2":"4534"
   },   
];

json.forEach(item => delete item.value2);
