在javascript中从类数组中获取对象

Question

我有一个类似的javascript类,

class Snake{
    constructor(id, trail){
        this.velocityX = 0;
        this.velocityY = -1;
        this.trail = trail;
        this.id = id;
    }
    moveRight(){
        console.log('move');
    }
}

和一个存储Snake对象的数组.

this.snakeList = new Array();
this.snakeList.push(new Snake(10, newSnakeTrail));
this.snakeList.push(new Snake(20, newSnakeTrail));
this.snakeList.push(new Snake(30, newSnakeTrail));
this.snakeList.push(new Snake(22, newSnakeTrail));
this.snakeList.push(new Snake(40, newSnakeTrail));

例如,我想从id为20的数组中删除该元素.

我怎样才能做到这一点？

Answer 1

那这个呢

this.snakeList = this.snakeList.filter(x => x.id != 20);

let snakes = [{name: 'fuss', id: 10}, {name: 'huss', id: 20}, {name: 'hurr', id: 60}]
//Before removal
console.log("Before removal");
console.log(snakes);

snakes = snakes.filter(x => x.id != 20);

//After removal
console.log("After removal");
console.log(snakes);
