通过传递其值来删除项目 --

const remove=(value)=>{
    myArray = myArray.filter(element=>element !=value);

}

将项目通过索引编号删除 -

  const removeFrom=(index)=>{
    myArray = myArray.filter((_, i)=>{
        return i!==index
    })
}

洛达什:

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"}]

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

快速解答和回答: 使用过滤器或拼盘方法 。

在此读取文档 :

过滤法:https://developmenter.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter Splice方法:https://developter.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/spice

Array.prototype.removeItem = function(a) {
    for (i = 0; i < this.length; i++) {
        if (this[i] == a) {
            for (i2 = i; i2 < this.length - 1; i2++) {
                this[i2] = this[i2 + 1];
            }
            this.length = this.length - 1
            return;
        }
    }
}

var recentMovies = ['Iron Man', 'Batman', 'Superman', 'Spiderman'];
recentMovies.removeItem('Superman');

 const Delete = (id) => {
      console.log(id)
     var index = Array.map(function(e){
      return e.id;
     
     }).indexOf(id);
     Array.splice(index,1);
     
}

我本人也有这个问题(在更换阵列是可以接受的情况下),

var filteredItems = this.items.filter(function (i) {
    return i !== item;
});

要给上面的片段略加上下文:

self.thingWithItems = {
    items: [],
    removeItem: function (item) {
        var filteredItems = this.items.filter(function (i) {
            return i !== item;
        });

        this.items = filteredItems;
    }
};

此解决方案应该同时使用引用项和值项。 它都取决于您是否需要保持对原始数组的引用, 以判断该解决方案是否适用 。
