这对我很管用。

你的数组:

DummyArray: any = [
    { "id": 1, "name": 'A' },
    { "id": 2, "name": 'B' },
    { "id": 3, "name": 'C' },
    { "id": 4, "name": 'D' }
]

功能:

remove() {
    this.DummyArray = this.DummyArray.filter(item => item !== item);
}

注意:这个函数删除数组中的所有对象。如果你想从数组中删除一个特定的对象，那么使用这个方法:

remove(id) {
    this.DummyArray = this.DummyArray.filter(item => item.id !== id);
}

类似于Abdus Salam Azad的答案，但将数组作为参数 / / https://love2dev.com/blog/javascript-remove-from-array/

function arrayRemove(arr:[], value:any) { 
    
    return arr.filter(function(ele){ 
        return ele != value; 
    });
}

let a: number[] = [];

a.push(1);
a.push(2);
a.push(3);

let index: number = a.findIndex(a => a === 1);

if (index != -1) {
    a.splice(index, 1);
}

console.log(a);

使用TypeScript扩展运算符(…)

// Your key
const key = 'two';

// Your array
const arr = [
    'one',
    'two',
    'three'
];

// Get either the index or -1
const index = arr.indexOf(key); // returns 0


// Despite a real index, or -1, use spread operator and Array.prototype.slice()    
const newArray = (index > -1) ? [
    ...arr.slice(0, index),
    ...arr.slice(index + 1)
] : arr;

只是想为数组添加扩展方法。

interface Array<T> {
      remove(element: T): Array<T>;
    }

    Array.prototype.remove = function (element) {
      const index = this.indexOf(element, 0);
      if (index > -1) {
        return this.splice(index, 1);
      }
      return this;
    };

还有一个使用Typescript的解决方案:

let updatedArray = [];
for (let el of this.oldArray) {
    if (el !== elementToRemove) {
        updated.push(el);
    }
}
this.oldArray = updated;
