9 从 JavaScript 阵列中删除元素的方法 - 附加如何安全清除 JavaScript 阵列

我更喜欢用filter():

var filtered_arr = arr.filter(function(ele){
   return ele != value;
})

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>

更新 :只有当您无法使用 ECMASCript 2015 (前称ES6) 时,才会推荐使用这种方法。 如果您可以使用这种方法, 其它答案则提供更清晰的落实。

这个格子在这里将解决您的问题, 并删除所有出现参数的情况, 而不是仅一个( 或指定值) 。

Array.prototype.destroy = function(obj){
    // Return null if no objects were found and removed
    var destroyed = null;

    for(var i = 0; i < this.length; i++){

        // Use while-loop to find adjacent equal objects
        while(this[i] === obj){

            // Remove this[i] and store it within destroyed
            destroyed = this.splice(i, 1)[0];
        }
    }

    return destroyed;
}

用法 :

var x = [1, 2, 3, 3, true, false, undefined, false];

x.destroy(3);         // => 3
x.destroy(false);     // => false
x;                    // => [1, 2, true, undefined]

x.destroy(true);      // => true
x.destroy(undefined); // => undefined
x;                    // => [1, 2]

x.destroy(3);         // => null
x;                    // => [1, 2]

这提供了一个前提值, 而不是一个值 。

注:这将更新给定的数组, 并返回受影响的行 。

用法

var removed = helper.remove(arr, row => row.id === 5 );

var removed = helper.removeAll(arr, row => row.name.startsWith('BMW'));

定义定义定义定义定义的定义定义定义定义定义的定义定义定义定义定义的定义定义定义定义定义定义的定义

var helper = {
 // Remove and return the first occurrence

 remove: function(array, predicate) {
  for (var i = 0; i < array.length; i++) {
   if (predicate(array[i])) {
    return array.splice(i, 1);
   }
  }
 },

 // Remove and return all occurrences

 removeAll: function(array, predicate) {
  var removed = [];

  for (var i = 0; i < array.length; ) {
   if (predicate(array[i])) {
    removed.push(array.splice(i, 1));
    continue;
   }
   i++;
  }
  return removed;
 },
};

查找index使用indexOf,然后删除该索引splice.

组合法通过删除现有元素和/或添加新元素来改变数组的内容。

const array = [2, 5, 9];

console.log(array);

const index = array.indexOf(5);
if (index > -1) { // only splice array when item is found
  array.splice(index, 1); // 2nd parameter means remove one item only
}

// array = [2, 9]
console.log(array); 

第二个参数的第二个参数splice是要删除的元素数。请注意splice修改现有数组,并返回含有已删除元素的新数组。

由于完整性的原因,此处为函数。第一个函数只删除一个单一事件(即删除第一个匹配5调自[2,5,9,1,5,8,5]),而第二个函数删除所有事件:

function removeItemOnce(arr, value) {
  var index = arr.indexOf(value);
  if (index > -1) {
    arr.splice(index, 1);
  }
  return arr;
}

function removeItemAll(arr, value) {
  var i = 0;
  while (i < arr.length) {
    if (arr[i] === value) {
      arr.splice(i, 1);
    } else {
      ++i;
    }
  }
  return arr;
}
// Usage
console.log(removeItemOnce([2,5,9,1,5,8,5], 5))
console.log(removeItemAll([2,5,9,1,5,8,5], 5))

在类型Script中,这些函数可用类型参数保持类型安全:

function removeItem<T>(arr: Array<T>, value: T): Array<T> { 
  const index = arr.indexOf(value);
  if (index > -1) {
    arr.splice(index, 1);
  }
  return arr;
}
