如何使用Lodash删除对象(查找和删除)

Question

我希望使用Lodash删除对象，使用uuid: xxx而不是xxx2的对象。

我怎么能用Lodash做这件事？

[
    {
        "uuid": "xxx",
        "name": "test"
    },
    {
        "uuid": "xxx2",
        "name": "test 2"
    }
]

我的实际代码：

_.forEach(this.objs, (obj, index, collection) => {
   _.remove(obj, {uuid})
})

Answer 1

您可以简单地使用.remove方法。

​

var objects = [
    {
        "uuid": "xxx",
        "name": "test"
    },
    {
        "uuid": "xxx2",
        "name": "test 2"
    }
];

_.remove(objects, o => o.uuid === 'xxx2');

console.log(objects);

Answer 2

你可以使用Array.prototype.filter()

​

let arr = [
    {
        "uuid": "xxx",
        "name": "test"
    },
    {
        "uuid": "xxx2",
        "name": "test 2"
    }
]


arr = arr.filter(e => e.uuid != 'xxx2');

console.log(arr);
