如果我有一个值为

{"__v":0,"_id":"528277c808cab8ac2b000001","password":"password",
"userId":5,"userName":"Austinsss","$$hashKey":"00F"}

我怎样才能从对象中完全删除 "$$hashKey":"00F" 。

使用delete（MDN）：

var foo = {"__v":0,"_id":"528277c808cab8ac2b000001","password":"password",
"userId":5,"userName":"Austinsss","$$hashKey":"00F"};

delete foo.$$hashKey;

如果您的键中有奇数字符，您也可以使用括号表示法：

delete foo['$$HashKey'];
