So fügen Sie ein Feld hinzu, um sie in JS zu gestalten
// original object { key1: "a", key2: "b"}
var obj = {
key1: "a",
key2: "b"
};
// adding new filed - you can use 2 ways
obj.key3 = "c"; // static
// or
obj["key3"] = "c"; // dynamic - 'key3' can be a variable
console.log(obj) // {key1: "a", key2: "b", key3: "c" }
