javascript - 如何在多个 JSON 对象中保存循环数据

Question

我在循环中有一些变量，需要将它们保存在 JSON 中。但需要确保下一次循环迭代时，之前创建的 JSON 不会被覆盖。

try {
  ayats.forEach(function(element) {
    if (element.toLowerCase().includes(request.params.find.toLowerCase())===true)
    {
      counting++;
      element=JSON.parse(element);
      Surah_Name = element.SuratName;
      Ayat_No = element.AyatNo;
      x = "In Surah "+ element.SuratName+", Ayat Number: "+element.AyatNo+", Quran says: "+ element.Translation;

      // Here some logic to save Surah_Name, Ayat_No and x in JSON
    }
  }
}

所需的输出是这样的:

{
 "data1":{"Surah_Name": Surah_Name,"Ayat_No": Ayat_No, "x":x},
 "data2":{"Surah_Name": Surah_Name,"Ayat_No": Ayat_No, "x":x},
 "data3":{"Surah_Name": Surah_Name,"Ayat_No": Ayat_No, "x":x},
}

Answer 1

试试这个:

function getData(ayats){

const parentObj={};
let counting=0;
  ayats.forEach(function(element) {
    if (element.toLowerCase().includes(request.params.find.toLowerCase())===true)
    {
      counting++;
      element=JSON.parse(element);
      Surah_Name = element.SuratName;
      Ayat_No = element.AyatNo;
      x = "In Surah "+ element.SuratName+", Ayat Number: "+element.AyatNo+", Quran says: "+ element.Translation;
      const tempObj={
        Surah_Name,
        Ayat_No,
        x
      }
      parentObj[`data${counting}`]=tempObj
      // Here some logic to achieve the required output
    }
  })
  return parentObj;
}

console.log(getData(ayats))
