Несколько операторов If не работают в Javascript

Question

Да, я знаю, это выглядит плохо.Я новичок в JS.

Итак, я создаю сайт, который получает пользовательский ввод с помощью значения <select> и переносит его на новую страницу с помощью form action="result.html" method="GET".

На выбор предлагается два тега <select>: один имеет 40 вариантов, другой - более 100.

Мне нужен лучший способ сделать это, как вы можете видеть из моегоприведенный ниже код не только не работает, но и занимает слишком много места.

Спасибо, и если вам понадобится какая-либо другая информация, я с удовольствием предоставлю ее.

var getString = window.location.search;

Answer 1

Почему бы просто:

if (getString.indexOf("devicetype" > -1)) {
    document.getElementById('pleasewait-deviceinfo').innerHTML = "tbd";
    document.getElementById('pleasewait-tip').innerHTML = "tbd";
}

, так как код делает одно и то же для каждого случая ...

Answer 2

Использование цикла for

var i;
for (i = 1; i <= 100; i++) { 
  if (getString.indexOf("devicetype=" + i > -1)) {
    document.getElementById('pleasewait-deviceinfo').innerHTML = "tbd";
    document.getElementById('pleasewait-tip').innerHTML = "tbd";
  }
}
