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>

Array.prototype.remove = function(x) {
    var y=this.slice(x+1);
    var z=[];
    for(i=0;i<=x-1;i++) {
        z[z.length] = this[i];
    }

    for(i=0;i<y.length;i++){
        z[z.length]=y[i];
    }

    return z;
}

大多数给定的回答都用于严格的比较, 意思是两个对象在内存( 或原始类型) 中引用完全相同的对象, 但通常您想要从具有一定值的数组中删除一个非原始对象。 例如, 如果您给服务器打电话, 并想要对照本地对象检查已检索到的对象 。

const a = {'field': 2} // Non-primitive object
const b = {'field': 2} // Non-primitive object with same value
const c = a            // Non-primitive object that reference the same object as "a"

assert(a !== b) // Don't reference the same item, but have same value
assert(a === c) // Do reference the same item, and have same value (naturally)

//Note: there are many alternative implementations for valuesAreEqual
function valuesAreEqual (x, y) {
   return  JSON.stringify(x) === JSON.stringify(y)
}


//filter will delete false values
//Thus, we want to return "false" if the item
// we want to delete is equal to the item in the array
function removeFromArray(arr, toDelete){
    return arr.filter(target => {return !valuesAreEqual(toDelete, target)})
}

const exampleArray = [a, b, b, c, a, {'field': 2}, {'field': 90}];
const resultArray = removeFromArray(exampleArray, a);

//resultArray = [{'field':90}]

数值AreEqual有替代/更快的操作,但这样可以操作。如果您有特定的字段要检查,也可以使用自定义的比较器(例如,有些已检索的 UUID 相对于本地的 UUID ) 。

2. 还注意到这是一个功能操作,意即它不改变原始阵列。

 (function removeFromArrayPolyfill() {
      if (window.Array.prototype.remove) return;
    
      Array.prototype.remove = function (value) {
        if (!this.length || !value) return;
    
        const indexOfValue = this.indexOf(value);
    
        if (indexOfValue >= 0) {
          this.splice(indexOfValue, 1);
        }
      };
    })();
    
    // testing polyfill
    const nums = [10, 20, 30];
    nums.remove(20);
    console.log(nums);//[10,30]

尝试使用此代码filter方法,您可以从数组中删除任何特定项。

let arr = [1, 2, 3, 4, 5, 6, 7, 8, 9];
function removeItem(arr, value) {
  return arr.filter(function (ele) {
    return ele !== value;
  });
}
console.log(removeItem(arr, 6));
