const Delete = (id) => {
      console.log(id)
     var index = Array.map(function(e){
      return e.id;
     
     }).indexOf(id);
     Array.splice(index,1);
     
}

您可以使用标准__proto__JavaScript 和定义此函数。例如,

let data = [];
data.__proto__.remove = (n) => { data = data.flatMap((v) => { return v !== n ? v : []; }) };

data = [1, 2, 3];
data.remove(2);
console.log(data); // [1,3]

data = ['a','b','c'];
data.remove('b');
console.log(data); // [a,c]

如果元素存在多个实例,您可以进行后回循环,以确保不破坏索引。

var myElement = "chocolate";
var myArray = ['chocolate', 'poptart', 'poptart', 'poptart', 'chocolate', 'poptart', 'poptart', 'chocolate'];

/* Important code */
for (var i = myArray.length - 1; i >= 0; i--) {
  if (myArray[i] == myElement) myArray.splice(i, 1);
}
console.log(myArray);

我对基底 JavaScript 阵列进行了相当高效的扩展:

Array.prototype.drop = function(k) {
  var valueIndex = this.indexOf(k);
  while(valueIndex > -1) {
    this.removeAt(valueIndex);
    valueIndex = this.indexOf(k);
  }
};

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。

删除一个数值,使用松放比较,不突变原始数组ES6

/**
 * Removes one instance of `value` from `array`, without mutating the original array. Uses loose comparison.
 *
 * @param {Array} array Array to remove value from
 * @param {*} value Value to remove
 * @returns {Array} Array with `value` removed
 */
export function arrayRemove(array, value) {
    for(let i=0; i<array.length; ++i) {
        if(array[i] == value) {
            let copy = [...array];
            copy.splice(i, 1);
            return copy;
        }
    }
    return array;
}
