JavaScript編輯對象內部的數組

Question

是否可以將項目推送到JavaScript對象內部的數組

這是我的代碼：

function test() {
this.array = [];

this.addItem = function() {
    this.array.push("someString");
}

this.removeItem = function() {
    this.array.remove(0);
}}

Answer 1

看這段代碼-

 var obj = { numbers: [1, 2, 3, 4] } obj.numbers.push(5) console.log(obj.numbers) 

Answer 2

如果要使用對象，則可以使用Javascript ES6

 class Test { constructor() { this.array = []; } addItem(item) { this.array.push(item); } removeItem() { this.array.splice(0, 1); } removeItemByIndex(index) { this.array.splice(index, 1); } } const test = new Test(); test.addItem('Some Item'); test.addItem('Some Item 2'); console.log(test.array); test.removeItem(); console.log(test.array);
