我看到许多抱怨，删除方法不是内置的。考虑使用Set而不是array——它有内置的添加和删除方法。

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);

这是我的解决方案:

onDelete(id: number) {
    this.service.delete(id).then(() => {
        let index = this.documents.findIndex(d => d.id === id); //find index in your array
        this.documents.splice(index, 1);//remove element from array
    });

    event.stopPropagation();
}

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;
    };

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 foo_object; // Itemitem(object here) to remove
this.foo_objects = this.foo_objects.filter(obj => return obj !== foo_object);
