javascript - 我们如何搜索并找到与某些 `Array number` 匹配的属性名称 `schools` 的 `search text`

转载作者：行者123 更新时间：2023-11-30 13:53:52

我们如何在给定的复杂 Json 数组中搜索并找到与某些搜索文本匹配的属性名称 schools 的数组编号 below: 我试过下面的代码，但它不起作用。

const searchText = "South School";
var myArr = [];
myArr = response.body.schools;

 var results = myArr.filter(function(myArr) {
   return myArr.schools.indexOf(searchText) > -1;
 });

根据上面的搜索文本，我需要从下面的 json 中找到与搜索文本匹配的数组编号。当我观察 chrome 控制台时，我可以看到以下数组范围。

最佳答案

根据你的样本数据，你需要过滤3次。

var searchText = "South School";
var schools = [];
var arr = [
