我还有一个从阵列中移除的好办法:

var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = words.filter(word => word.length > 6);

console.log(result);
// expected output: Array ["exuberant", "destruction", "present"]

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

你可以轻而易举地用过滤过滤器方法 :

function remove(arrOriginal, elementToRemove){
    return arrOriginal.filter(function(el){return el !== elementToRemove});
}
console.log(remove([1, 2, 1, 0, 3, 1, 4], 1));

这将清除数组中的所有元素, 并且运行速度比slice和indexOf.

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}]

    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]

您可以用所有存取器示例创建索引 :

<div >
</div>

function getIndex($id){
  return (
    this.removeIndex($id)
    alert("This element was removed")
  )
}


function removeIndex(){
   const index = $id;
   this.accesor.id.splice(index.id) // You can use splice for slice index on
                                    // accessor id and return with message
}

<div>
    <fromList>
        <ul>
            {...this.array.map( accesors => {
                <li type="hidden"></li>
                <li>{...accesors}</li>
            })

            }
        </ul>
    </fromList>

    <form id="form" method="post">
        <input  id="{this.accesors.id}">
        <input type="submit" callbackforApplySend...getIndex({this.accesors.id}) name="sendendform" value="removeIndex" >
    </form>
</div>

删除单个元素

function removeSingle(array, element) {
    const index = array.indexOf(element)
    if (index >= 0) {
        array.splice(index, 1)
    }
}

删除多个元素, 位置内

这对于确保算法在O(N)时间运行更为复杂。

function removeAll(array, element) {
    let newLength = 0
    for (const elem of array) {
        if (elem !== number) {
            array[newLength++] = elem
        }
    }
    array.length = newLength
}

删除多个元素,创建新对象

array.filter(elem => elem !== number)
