I am working with HTML and JS and I am trying to add a click event listener so that the index = 0 value updates automatically on click.
Depending on which .tab element I click, the content inside of the div.tab should change to display either Hello1, Hello2 or Hello3.
The first tab should display the tab content hello1 accordingly.
I have provided both with data attributes in the HTML. I want the corresponding div.tab content to be output if both have the same data attribute with vanilla JS.
JS
const tabbarContent = document.querySelectorAll(".tab-content");
const tabbarButtons = document.querySelectorAll(".tab");
const index = 0;
tabbarContent[index].classList.add('active');
tabbarButtons[index].classList.add('active');
const dataAttribute1 = tabbarButtons[index].getAttribute("data-tab");
const dataAttribute2 = tabbarContent[index].getAttribute("data-tab");
function clickTab() {
for (let index = 0; index.length; index++) {
if (dataAttribute1[index] === dataAttribute2[index]) {
dataAttribute2.classList.add("active");
}
}
}
tabbarButtons[index].addEventListener("click", clickTab);
HTML
<div class="container">
<div class="inner-container">
<div class="tab tab1" data-tab="1">
1
</div>
<div class="tab tab2" data-tab="2">
2
</div>
<div class="tab tab3" data-tab="3">
3
</div>
</div>
<div class="inner-container">
<div class="tab-content content1" data-tab="1">
<h1>Hello1</h1>
</div>
<div class="tab-content content2" data-tab="2">
<h1>Hello2</h1>
</div>
<div class="tab-content content3" data-tab="3">
<h1>Hello3</h1>
</div>
</div>
</div>
Thanks Jessy
If I understand correctly what you want to achieve, you could do something like:
const tabbarButtons = document.querySelectorAll(".tab");
const tabbarContents = document.querySelectorAll(".tab-content");
tabbarButtons.forEach((tabBtn) => {
tabBtn.addEventListener('click', () => {
tabbarContents.forEach(tabCnt => {
if (tabCnt.dataset.tab === tabBtn.dataset.tab) {
tabCnt.classList.add('active');
} else {
tabCnt.classList.remove('active');
}
})
});
}).tab {
display: inline-block;
padding: 5px;
border: 1px solid #ccc;
}
.tab-content {
display: none;
}
.tab-content.active {
display: block;
}<div class="container">
<div class="inner-container">
<div class="tab tab1" data-tab="1">
1
</div>
<div class="tab tab2" data-tab="2">
2
</div>
<div class="tab tab3" data-tab="3">
3
</div>
</div>
<div class="inner-container">
<div class="tab-content content1" data-tab="1">
<h1>Hello1</h1>
</div>
<div class="tab-content content2" data-tab="2">
<h1>Hello2</h1>
</div>
<div class="tab-content content3" data-tab="3">
<h1>Hello3</h1>
</div>
</div>
</div>
