删除 JSON 元素

我想从 JSON 中删除 JSON 元素或一整行。

我有以下 JSON 字符串：

{
   "result":[
       {
           "FirstName": "Test1",
           "LastName":  "User",
       },
       {
           "FirstName": "user",
           "LastName":  "user",
       },
       {
           "FirstName": "Ropbert",
           "LastName":  "Jones",
       },
       {
           "FirstName": "hitesh",
           "LastName":  "prajapti",
       }
   ]
}

var json = { ... };
var key = "foo";
delete json[key]; // Removes json.foo from the dictionary.

您可以使用splice https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/splice从数组中删除元素。
