javascript - LINQ WHERE 子句等效于 javascript

Question

我希望从我的 javascript 数组“lstObj”中提取信息，如下所示:

[
  {
    "DealerId": "1",
    "Type": "Apple,Orange"
  },
  {
    "DealerId": "2",
    "Type": "Mango"
  },
  {
    "DealerId": "3",
    "Type": "Mango"
  }
]

我想检查是否有 Type = Mango 且 DealerID 不为 2 的商品。在 C# linq 中，我会做这样的事情:

if(lstObj.Any(x=>x.Type.Split(',').Contains("Mango") && x.DealerID != 2))
{
      //Do something
}

如何使用 javascript 实现同样的效果？

Answer 1

这应该可以。如果没有项目将返回空数组，否则将返回项目。

let result = lstObj.filter(dealer =>  dealer.Type.split(',').includes('Mango') && dealer.DealerId != 2);

let lstObj = [
  {
    "DealerId": "1",
    "Type": "Apple,Orange"
  },
  {
    "DealerId": "2",
    "Type": "Mango"
  },
  {
    "DealerId": "3",
    "Type": "Mango"
  }
]

let result = lstObj.filter(dealer => dealer.Type.split(',').includes('Mango') && dealer.DealerId != 2)

console.log(result)
