Question

提问by Bobimaru

I have a variable data that contains some key-value pairs like this:

我有一个包含一些键值对的变量数据，如下所示：

var data = {
    "1": 127,
    "2": 236,
    "3": 348
}

router.delete('/values/:id', function(req, res, next){
    var id = req.params.id;

})

How can I delete the key-value pair that has a key equal to the id variable?

如何删除键等于 id 变量的键值对？

Answer 1

delete data[req.params.id]or delete data[id]should work.

delete data[req.params.id]或delete data[id]应该工作。
