我想根据ECMAScript 6。假设您拥有如下阵列:

let arr = [1,2,3,4];

如果您想要在特殊索引中删除2,写下以下代码:

arr.splice(2, 1); //=> arr became [1,2,4]

但是,如果你想删除一个特殊项目,比如3并且你不知道它的索引, 做如下:

arr = arr.filter(e => e !== 3); //=> arr became [1,2,4]

提示提示:请使用箭头函数进行过滤回击,除非您得到空数组。

如果您使用现代浏览器, 您可以使用. 过滤器 。

Array.prototype.remove = function(x){
    return this.filter(function(v){
        return v !== x;
    });
};

var a = ["a","b","c"];
var b = a.remove('a');

如果数组含有重复的值,而您想要删除目标的所有发生点, 那么这就是前进的道路...

let data = [2, 5, 9, 2, 8, 5, 9, 5];
let target = 5;
data = data.filter(da => da !== target);

注: - 过滤器不会改变原始数组;相反它会创建一个新的数组。

所以再次分配很重要。

这又引出了另一个问题,你无法制造变数const应该是:let或var.

let a1 = {name:'a1'}
let a2 = {name:'a2'}
let a3 = {name:'a3'}
let list = [a1, a2, a3]
_.remove(list, a2)
//list now is [{name: "a1"}, {name: "a3"}]

选中此项以获取细节 :. remove( 数组, [预测=)(. 身份]))

您可以使用标准__proto__JavaScript 和定义此函数。例如,

let data = [];
data.__proto__.remove = (n) => { data = data.flatMap((v) => { return v !== n ? v : []; }) };

data = [1, 2, 3];
data.remove(2);
console.log(data); // [1,3]

data = ['a','b','c'];
data.remove('b');
console.log(data); // [a,c]

使用不同种类数组的过滤器

    **simple array**
    const arr = ['1','2','3'];
    const updatedArr = arr.filter(e => e !== '3');
    console.warn(updatedArr);

    **array of object**
    const newArr = [{id:1,name:'a'},{id:2,name:'b'},{id:3,name:'c'}]
    const updatedNewArr = newArr.filter(e => e.id !== 3);
    console.warn(updatedNewArr);

    **array of object with different parameter name**
    const newArr = [{SINGLE_MDMC:{id:1,cout:10}},{BULK_MDMC:{id:1,cout:15}},{WPS_MDMC:{id:2,cout:10}},]
    const newArray = newArr.filter((item) => !Object.keys(item).includes('SINGLE_MDMC'));
    console.log(newArray)
