JavaScript 使用替换功能进行序列化
示例
replacer可以使用一个函数来过滤或转换要序列化的值。
const userRecords = [
{name: "Joe", points: 14.9, level: 31.5},
{name: "Jane", points: 35.5, level: 74.4},
{name: "Jacob", points: 18.5, level: 41.2},
{name: "Jessie", points: 15.1, level: 28.1},
];
//删除名称和将整数舍入为整数以在共享之前匿名记录
const anonymousReport = JSON.stringify(userRecords, (key, value) =>
key === 'name'
? undefined
: (typeof value === 'number' ? Math.floor(value) : value)
);这将产生以下字符串：
'[{"points":14,"level":31},{"points":35,"level":74},{"points":18,"level":41},{"points":15,"level":28}]'
