I have some javascript that I want to convert to jQuery... How do we change javascript to jquery code? Do we just change the document.getElementById > $? Do we change document.querySelectorAll > $ too? Does the function portion also need to be tweak?
Kindly see my code apprehend below:
// Home Page Gallery
let i = 0; // current slide
let j = 5; // total slides
const dots = document.querySelectorAll(".dot-container button");
const images = document.querySelectorAll(".image-container img");
function next() {
document.getElementById("content" + (i + 1)).classList.remove("active");
i = (j + i + 1) % j;
document.getElementById("content" + (i + 1)).classList.add("active");
indicator(i + 1);
}
function prev() {
document.getElementById("content" + (i + 1)).classList.remove("active");
i = (j + i - 1) % j;
document.getElementById("content" + (i + 1)).classList.add("active");
indicator(i + 1);
}
function indicator(num) {
dots.forEach(function (dot) {
dot.style.backgroundColor = "transparent";
});
document.querySelector(".dot-container button:nth-child(" + num + ")").style.backgroundColor = "#107e31";
}
function dot(index) {
images.forEach(function (image) {
image.classList.remove("active");
});
document.getElementById("content" + index).classList.add("active");
i = index - 1;
indicator(index);
}
// FAQ JS
let toggles = document.getElementsByClassName('toggle');
let contentDiv = document.getElementsByClassName('content');
let icons = document.getElementsByClassName('icon');
for(let i=0; i<toggles.length; i++){
toggles[i].addEventListener('click', ()=>{
if( parseInt(contentDiv[i].style.height) != contentDiv[i].scrollHeight){
contentDiv[i].style.height = contentDiv[i].scrollHeight + "px";
toggles[i].style.color = "#0084e9";
icons[i].classList.remove('fa-plus');
icons[i].classList.add('fa-minus');
}
else{
contentDiv[i].style.height = "0px";
toggles[i].style.color = "#111130";
icons[i].classList.remove('fa-minus');
icons[i].classList.add('fa-plus');
}
for(let j=0; j<contentDiv.length; j++){
if(j!==i){
contentDiv[j].style.height = "0px";
toggles[j].style.color = "#111130";
icons[j].classList.remove('fa-minus');
icons[j].classList.add('fa-plus');
}
}
});
}
When using $() with selectors, it's very similar to document.querySelectorAll().
So, if you wanted to query for a specific ID, you'd need to use a pound symbol # in front of the ID:
$('#some-id')
Really though, there's no reason I can think of these days to use jQuery. Additionally, you could probably remove the need for any of this JavaScript by simply using anchor fragments/hash and the :target selector. Your URLs could be like somepage.html#slide-1.
