'Javascript menu changer
I have tried making a menu in javascript that changes the name, description and image of the 8 different menu items. As of yesterday it worked but something happened and now it doesn't work. I asked my teacher and she doesnt know whats wrong either.
function menytema1() {
var cards = document.getElementsByClassName("card");
var title = document.getElementsByClassName("accordion-button")
var description = document.getElementsByClassName("accordion-body")
for (i = 0; i < cards.length; i++) {
let images = cards[i].getElementsByTagName("img");
title[i].innerHTML = "En typ av Pizza";
description[i].innerHTML = "Beskriving av Pizzan"
for (let index = 0; index < images.length; index++) {
images[index].src = "../img/pizza_card.jpg"
}
}
}
function menytema2() {
var cards = document.getElementsByClassName("card");
var title = document.getElementsByClassName("accordion-button")
var description = document.getElementsByClassName("accordion-body")
for (i = 0; i < cards.length; i++) {
let images = cards[i].getElementsByTagName("img");
title[i].innerHTML = "En sorts Kebab";
description[i].innerHTML = "Beskriving av Kebaben"
for (let index = 0; index < images.length; index++) {
images[index].src = "../img/kebab_card.jpg"
}
}
}
function menytema3() {
var cards = document.getElementsByClassName("card");
var title = document.getElementsByClassName("accordion-button")
var description = document.getElementsByClassName("accordion-body")
for (i = 0; i < cards.length; i++) {
let images = cards[i].getElementsByTagName("img");
title[i].innerHTML = "En variant av Gyros";
description[i].innerHTML = "Beskriving av Gyros"
for (let index = 0; index < images.length; index++) {
images[index].src = "../img/gyros_card.jpg"
}
}
