数组出功能javascript

我正在做一个JavaScript的学校练习，我必须模拟预订系统的航班。要查看已经预订的用户，我创建了两个布尔数组（每个类一个），并且当您预订该地点时，我将其置为false，问题是数组不会放入false ...任何解决方案？对不起英文不好！数组出功能javascript

<script> 
    var eco = [true, true, true, true, true]; 
    var pri = [true, true, true, true, true]; 
    function economica(n)

     var cambiato = false; 
     for (var i = 0; i < 4; i++) { 
      if (eco[i] == true) { 
       switch (i) { 
        case 0: document.getElementById("e1").innerHTML = n; break; 
        case 1: document.getElementById("e2").innerHTML = n; break; 
        case 2: document.getElementById("e3").innerHTML = n; break;

对于一个需要5浏览：'为（VAR I = 0;我<5; i ++）'或给这些跨度一个类并遍历document.querySelectorAll（“spanclass”）或者仅仅是if（pri [i] == true）document.getElementById（“p”+（i + 1））。 innerHTML = n; }' – mplungjan

代码中的重复使我的眼睛流血。请细化您的代码。你应该为教练和首先有一个单一的功能，而且这个开关不适合活下去。 – jcaron

你有一个错字导致此错误：

eco[i] == false;

应该

eco[i] = false;

而在你的第二个功能相同的错误 - DRY

，您需要更改的循环条件为好，i < 5或i <=4

再一次同样的错误，在这两个功能 - DRY
