使用typescript在数组中批量删除 [英] Bulk delete in array by using typescript

问题描述

我想使用打字稿从数组中批量删除。

I want to do bulk delete from an array using typescript.

我是通过使用for循环来完成的。

I did it by using for loop.

this.versions = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12];
this.selectedVersions = [1, 2, 3, 4, 5, 6];
for (let i = 0; i < this.selectedVersions.length; i++) {
  this.versions = this.removeObjectFromArray(this.versions, this.selectedVersions[i]);
}


//removing a object from array
removeObjectFromArray(listOfdata: any, data: any) {
  let index = listOfdata.findIndex(function (o) {
    return o === data;
  })
  listOfdata.splice(index, 1);
  return listOfdata;
}

但我不喜欢使用 for循环。所以让我知道如何使用打字稿在数组中进行批量删除。

But I don't like to use for loop.so let me know how to do bulk delete in array using typescript.

推荐答案

你可以使用数组过滤器：

You can just use array filter:

var versions = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12];
var selectedVersions = [1, 2, 3, 4, 5, 6];

versions = versions.filter(el => !selectedVersions.includes(el));
console.log(versions);
