使用两个变量的 for 循环？

Question

我正在编写一些代码，其中有两个变量，其中有几个不同的团队。我是 JS 新手，似乎无法理解如何在同一个 for 循环中打印两个变量的值。let jsonData = pm.response.json();let home_team = []let away_team = []let home_team_id = []let away_team_id = []//console.log(jsonData)jsonData.games.forEach((b)=>{    home_team.push(b.home.name)    away_team.push(b.away.name)})pm.environment.set("Home_Team",home_team)pm.environment.set("Away_Team",away_team)//console.log(pm.environment.get("Home Team"))//console.log(pm.environment.get("Away Team"))for (const element of home_team) {  console.log(element + "VS" + away_team);}现在我知道上面的代码不会运行，我只是显示我想要打印到控制台的内容，我不知道如何添加在同一循环中引用away_team 的第二个元素。话虽如此，当我将 for 循环设置为for (const element of home_team) {  console.log(element);}它可以毫无问题地打印我的主队列表，但我确实正在寻找一个可以打印我的主队和客队的循环，列表大小是相同的并且始终如此。

Answer 1

只需使用索引 for 循环

for(let i = 0;i < home_team.length; i++) {
  console.log(home_team[i] + "VS" + away_team[i]);
}

您还可以使用forEach

home_team.forEach((item, index) => console.log(item + "VS" + away_team[index]));

Answer 2

如果两个数组包含相同数量的项目，那么您可以使用普通的 for 循环来访问具有相同索引的每个项目，如下所示 -

let home_team = ["A", "B", "C"];

let away_team = ["D", "E", "F"];

for(let i=0; i<home_team.length; i++){

  console.log(`${home_team[i]} VS ${away_team[i]}`);

}

或者，您也可以在 for 循环中使用多个计数器，如下所示（尽管您现在不需要这个 -

let home_team = ["A", "B", "C"];

let away_team = ["D", "E", "F"];

for(let i=0,j=2; i<home_team.length; i++, j--){

  console.log(`${home_team[i]} VS ${away_team[j]}`);

}
