Array.prototype.remove = function(start, end) {
        var n = this.slice((end || start) + 1 || this.length);
        return this.length = start < 0 ? this.length + start : start,
        this.push.apply(this, n)
    }

start和end可以是负数。在这种情况下,它们会从数组的末尾计数。

如果只有start中指定,只删除一个元素。

函数返回新数组长度。

z = [0,1,2,3,4,5,6,7,8,9];

newlength = z.remove(2,6);

(8) [0, 1, 7, 8, 9]

z=[0,1,2,3,4,5,6,7,8,9];

newlength = z.remove(-4,-2);

(7) [0, 1, 2, 3, 4, 5, 9]

z=[0,1,2,3,4,5,6,7,8,9];

newlength = z.remove(3,-2);

(4) [0, 1, 2, 9]

根据所有主要正确的答复并考虑到建议的最佳做法(特别是不直接使用Array.prototype),我提出了以下代码:

function arrayWithout(arr, values) {
  var isArray = function(canBeArray) {
    if (Array.isArray) {
      return Array.isArray(canBeArray);
    }
    return Object.prototype.toString.call(canBeArray) === '[object Array]';
  };

  var excludedValues = (isArray(values)) ? values : [].slice.call(arguments, 1);
  var arrCopy = arr.slice(0);

  for (var i = arrCopy.length - 1; i >= 0; i--) {
    if (excludedValues.indexOf(arrCopy[i]) > -1) {
      arrCopy.splice(i, 1);
    }
  }

  return arrCopy;
}

在审查上述功能时,尽管运作良好,但我意识到业绩可能有所改进。 使用ES6而不是ES5是一种更好的方法。

const arrayWithoutFastest = (() => {
  const isArray = canBeArray => ('isArray' in Array) 
    ? Array.isArray(canBeArray) 
    : Object.prototype.toString.call(canBeArray) === '[object Array]';

  let mapIncludes = (map, key) => map.has(key);
  let objectIncludes = (obj, key) => key in obj;
  let includes;

  function arrayWithoutFastest(arr, ...thisArgs) {
    let withoutValues = isArray(thisArgs[0]) ? thisArgs[0] : thisArgs;

    if (typeof Map !== 'undefined') {
      withoutValues = withoutValues.reduce((map, value) => map.set(value, value), new Map());
      includes = mapIncludes;
    } else {
      withoutValues = withoutValues.reduce((map, value) => { map[value] = value; return map; } , {}); 
      includes = objectIncludes;
    }

    const arrCopy = [];
    const length = arr.length;

    for (let i = 0; i < length; i++) {
      // If value is not in exclude list
      if (!includes(withoutValues, arr[i])) {
        arrCopy.push(arr[i]);
      }
    }

    return arrCopy;
  }

  return arrayWithoutFastest;  
})();

如何使用 :

const arr = [1,2,3,4,5,"name", false];

arrayWithoutFastest(arr, 1); // will return array [2,3,4,5,"name", false]
arrayWithoutFastest(arr, 'name'); // will return [2,3,4,5, false]
arrayWithoutFastest(arr, false); // will return [2,3,4,5]
arrayWithoutFastest(arr,[1,2]); // will return [3,4,5,"name", false];
arrayWithoutFastest(arr, {bar: "foo"}); // will return the same array (new copy)

我目前正在写博客文章, 其中我已设定数个无问题的阵列解决方案基准, 并比较运行时间。 一旦我完成此文章, 我将更新此答案, 并用链接更新。 仅供参考, 我比较了上述与没有 Lodash 的比较, 以防浏览器支持Map注意我没有用Array.prototype.indexOf或Array.prototype.includes将exlcude Values 包装在Map或Object让查询更快!

您可以为此创建一个原型。只需通过数组元素和您想要从数组元素中删除的值:

Array.prototype.removeItem = function(array,val) {
    array.forEach((arrayItem,index) => {
        if (arrayItem == val) {
            array.splice(index, 1);
        }
    });
    return array;
}
var DummyArray = [1, 2, 3, 4, 5, 6];
console.log(DummyArray.removeItem(DummyArray, 3));

您可以扩展数组对象以定义自定义的删除函数如下:

let numbers = [1,2,4,4,5,3,45,9];

numbers.delete = function(value){
    var indexOfTarget = this.indexOf(value)

    if(indexOfTarget !== -1)
    {
        console.log("array before delete " + this)
        this.splice(indexOfTarget, 1)
        console.log("array after delete " + this)
    }
    else{
        console.error("element " + value + " not found")
    }
}
numbers.delete(888)
// Expected output:
// element 888 not found
numbers.delete(1)

// Expected output;
// array before delete 1,2,4,4,5,3,45,9
// array after delete 2,4,4,5,3,45,9

var index,
    input = [1,2,3],
    indexToRemove = 1;
    integers = [];

for (index in input) {
    if (input.hasOwnProperty(index)) {
        if (index !== indexToRemove) {
            integers.push(result); 
        }
    }
}
input = integers;

此解决方案将需要一系列输入, 并将通过输入查找要删除的值。 这将在整个输入数组中循环, 结果将是第二个已经删除了特定索引的数组整数组。 然后将整数组复制到输入数组中 。

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');
