JavaScript编辑对象内部的数组

Question

Is it somehow possible to push items to an array inside of a JavaScript object

Here my code:

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

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

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

Answer 1

Look at this code-

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

Answer 2

If you want to work with Objects, you can use 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);
