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, 我已将数个阵列解决方案设定为基准, 没有问题, 并比较运行时间 。 一旦我完成该文章, 我将更新此答案, 并使用链接 。 只需告知您, 我将以上内容与没有浏览器支持地图的 Lodash 比较, 以防浏览器支持地图, 它比 Lodash 还要快! 注意我没有使用 Array. prototype. indexof 或 Array. prototype 。 包含在地图或天体中将ExcludeValue 包装成快的查询 !

使用 jQuery. grep () :

对我而言,越简单越好,2018年(2019年左右),我给你这个(近一点)单行话,回答最初的问题:

Array.prototype.remove = function (value) {
    return this.filter(f => f != value)
}

有用的是,你可以用在咖喱的表达方式上,比如:

[1,2,3].remove(2).sort()

从数组中删除项目的最佳方法是使用过滤法。 . filter () 返回没有过滤过的项目的新数组 。

items = items.filter(e => e.id !== item.id);

. filter () 方法映射为完整的数组, 当我返回真实状态时, 它会将当前项目推到过滤的数组。 在此过滤器中读取更多 。

我刚刚通过对象.defineProperty在 Array. prototype 上创建了一个多填充器, 以便删除一个阵列中想要的元素, 而不会导致在... 的... 。

if (!Array.prototype.remove) {
  // Object.definedProperty is used here to avoid problems when iterating with "for .. in .." in Arrays
  // https://stackoverflow.com/questions/948358/adding-custom-functions-into-array-prototype
  Object.defineProperty(Array.prototype, 'remove', {
    value: function () {
      if (this == null) {
        throw new TypeError('Array.prototype.remove called on null or undefined')
      }

      for (var i = 0; i < arguments.length; i++) {
        if (typeof arguments[i] === 'object') {
          if (Object.keys(arguments[i]).length > 1) {
            throw new Error('This method does not support more than one key:value pair per object on the arguments')
          }
          var keyToCompare = Object.keys(arguments[i])[0]

          for (var j = 0; j < this.length; j++) {
            if (this[j][keyToCompare] === arguments[i][keyToCompare]) {
              this.splice(j, 1)
              break
            }
          }
        } else {
          var index = this.indexOf(arguments[i])
          if (index !== -1) {
            this.splice(index, 1)
          }
        }
      }
      return this
    }
  })
} else {
  var errorMessage = 'DANGER ALERT! Array.prototype.remove has already been defined on this browser. '
  errorMessage += 'This may lead to unwanted results when remove() is executed.'
  console.log(errorMessage)
}

删除整数值

var a = [1, 2, 3]
a.remove(2)
a // Output => [1, 3]

删除字符串值

var a = ['a', 'ab', 'abc']
a.remove('abc')
a // Output => ['a', 'ab']

删除布尔值

var a = [true, false, true]
a.remove(false)
a // Output => [true, true]

也可以通过此 Array. prototype. remove 方法从数组中移除对象。您只需要指定要删除对象的键值 {% 。

删除对象值

var a = [{a: 1, b: 2}, {a: 2, b: 2}, {a: 3, b: 2}]
a.remove({a: 1})
a // Output => [{a: 2, b: 2}, {a: 3, b: 2}]
