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)

 (function removeFromArrayPolyfill() {
      if (window.Array.prototype.remove) return;
    
      Array.prototype.remove = function (value) {
        if (!this.length || !value) return;
    
        const indexOfValue = this.indexOf(value);
    
        if (indexOfValue >= 0) {
          this.splice(indexOfValue, 1);
        }
      };
    })();
    
    // testing polyfill
    const nums = [10, 20, 30];
    nums.remove(20);
    console.log(nums);//[10,30]

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
    })
}

const arr = [1, 2, 3, 4, 5]
console.log(arr) // [ 1, 2, 3, 4, 5 ]

假设你想从Arr删除3号

const newArr = arr.filter(w => w !==3)
console.log(newArr) // [ 1, 2, 4, 5 ]

您可以使用lodash_.pull(平衡数组). pullAt(阵数数组)或_. 无 _(不变异阵列)

var array1 = ['a', 'b', 'c', 'd']
_.pull(array1, 'c')
console.log(array1) // ['a', 'b', 'd']

var array2 = ['e', 'f', 'g', 'h']
_.pullAt(array2, 0)
console.log(array2) // ['f', 'g', 'h']

var array3 = ['i', 'j', 'k', 'l']
var newArray = _.without(array3, 'i') // ['j', 'k', 'l']
console.log(array3) // ['i', 'j', 'k', 'l']

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 。
