//This function allows remove even array from array
var removeFromArr = function(arr, elem) { 
    var i, len = arr.length, new_arr = [],
    sort_fn = function (a, b) { return a - b; };
    for (i = 0; i < len; i += 1) {
        if (typeof elem === 'object' && typeof arr[i] === 'object') {
            if (arr[i].toString() === elem.toString()) {
                continue;
            } else {                    
                if (arr[i].sort(sort_fn).toString() === elem.sort(sort_fn).toString()) {
                    continue;
                }
            }
        }
        if (arr[i] !== elem) {
            new_arr.push(arr[i]);
        }
    }
    return new_arr;
}

使用实例

var arr = [1, '2', [1 , 1] , 'abc', 1, '1', 1];
removeFromArr(arr, 1);
//["2", [1, 1], "abc", "1"]

var arr = [[1, 2] , 2, 'a', [2, 1], [1, 1, 2]];
removeFromArr(arr, [1,2]);
//[2, "a", [1, 1, 2]]

当你需要移除一个在数组中多次出现的值时(例如。[1,2,2,2,4,5,6])。

function removeFrmArr(array, element) {
  return array.filter(e => e !== element);
};
var exampleArray = [1,2,3,4,5];
removeFrmArr(exampleArray, 3);
// return value like this
//[1, 2, 4, 5]

可以使用splice从数组中删除单个元素，但splice不能从数组中删除多个相似的元素。

function singleArrayRemove(array, value){
  var index = array.indexOf(value);
  if (index > -1) array.splice(index, 1);
  return array;
}
var exampleArray = [1,2,3,4,5,5];
singleArrayRemove(exampleArray, 5);
// return value like this
//[1, 2, 3, 4, 5]

你可以使用lodash的拉函数

Var ary = [' 3 '， ' 7 '， ' 11 ']; _。拉(氩,' 7 ');// [' 3 '， ' 11 '] console.log(必要) < script src = " https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.6.1/lodash.js " > < /脚本>

var index = array.indexOf('item');

if(index!=-1){

   array.splice(index, 1);
}

请不要使用带有delete的变体-它会在数组中留下一个洞，因为它不会在删除的项之后重新索引元素。

> Array.prototype.remove=function(v){
...     delete this[this.indexOf(v)]
... };
[Function]
> var myarray=["3","24","55","2"];
undefined
> myarray.remove("55");
undefined
> myarray
[ '3', '24', , '2' ]

这样看看:

delete this.arrayName[this.arrayName.indexOf(value)];
