如何从数组类型脚本中删除基于id的JSON对象

Question

我有一个购物车数组，我正在推动这些元素：

 cart = [];
 this.cart.push(item);

我还想根据id从这个cart[]数组中删除元素，对象结构如下：

[
    {
        id:1,
        imageUrl: "http://lorempixel.com/100/100/people?1",
        author: "Windward",
        handle: "@windwardstudios",
        body: "Looking for a better company reporting or docgen app?",
        totalLikes: 0,
        iLike: false
    },
    {
        id:2,
        imageUrl: "http://lorempixel.com/100/100/people?1",
        author: "Windward",
        handle: "@windwardstudios",
        body: "Looking for a better company reporting or docgen app?",
        totalLikes: 0,
        iLike: false
    }
]

我正在执行pop操作以删除添加到数组中的对象，但不幸的是，这是删除最后插入的项目。我不想要的。

this.cart.pop(); 

我怎样才能在打字稿中做到这一点？

您可以使用Array filter

    var idToDelete = 1;
    this.car = this.cart.filter(item=>item.id !=idToDelete );
