使用数组过滤过滤器方法 :

let array = [1, 2, 3, 4, 511, 34, 511, 78, 88];

let value = 511;
array = array.filter(element => element !== value);
console.log(array)

此函数从特定位置的数组中删除元素。

array.remove(position);

Array.prototype.remove = function (pos) {
    this.splice(pos, 1);
}

var arr = ["a", "b", "c", "d", "e"];
arr.remove(2); // remove "c"
console.log(arr);

如果您不知道要删除的项目的位置, 请使用这个 :

array.erase(element);

Array.prototype.erase = function(el) {
    let p = this.indexOf(el); // indexOf use strict equality (===)
    if(p != -1) {
        this.splice(p, 1);
    }
}

var arr = ["a", "b", "c", "d", "e"];
arr.erase("c");
console.log(arr);

我刚刚创建了一个多填充Array.prototype通过Object.defineProperty以删除数组中一个想要的元素,而不会在稍后通过for .. in ..

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]

也可以通过此方法从数组中移除对象Array.prototype.remove方法。只需指定key => value of the Object您想要删除。

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}]

最干净的:

var arr = ['1','2','3'];
arr = arr.filter(e => e !== '3');
console.warn(arr);

这也将删除重复(如果有的话)。

您可以使用ES6. 例如,在此情况下删除值“ 3” :

var array=['1','2','3','4','5','6']
var newArray = array.filter((value)=>value!='3');
console.log(newArray);

产出:

["1", "2", "4", "5", "6"]
