I designed two pages on the website.I want the second tab - btn, instead of the first tab - btn, to have id = "default" and accept the activate class when the link on page 1 is clicked and goes to page 2. As you can see in the html code, there is normally id = "default" and the activate class in tab1.But when the link on page 1 is clicked and page 2 appears, instead of tab1, the second tab has id = "default" and an activate class. Meanwhile, tab1 lacks id = "default" and the class is activated. Can I manage this with JavaScript? Thank you in advance for your cooperation, friends
//codes of javascript for page: 2
function tabs(e,name){
var tab_btn = document.getElementsByClassName('tab--btn');
var tab_content = document.getElementsByClassName('tab--content');
var supporItemsCard = document.querySelector('.support--items__card');
var i;
for( i = 0 ; i<tab_btn.length ; i++){
tab_btn[i].classList.remove('active');
}
for(i = 0 ; i<tab_content.length ; i++){
tab_content[i].style.display = 'none';
}
document.getElementById(name).style.display = 'block';
e.currentTarget.classList.add('active');
}
document.getElementById('default').click();page: 1
<a href=""> link page 1 </a>
page: 2
<ul class="support--items__cards">
<li class="support--items__card tab--btn" id="default" onclick="tabs(event,'tab1')">
<h4 class="support--items__card__title">TAB 1</h4>
</li>
<li class="support--items__card tab--btn" onclick="tabs(event,'tab2')">
<h4 class="support--items__card__title">TAB 2</h4>
</li>
<li class="support--items__card tab--btn" onclick="tabs(event,'tab3')">
<h4 class="support--items__card__title">TAB 3</h4>
</li>
<ul>
<div class="content">
<div id="tab1" class="tab--content">
content tab 1
</div>
<div id="tab2" class="tab--content">
content tab 2
</div>
<div id="tab3" class="tab--content">
content tab 3
</div>
</div>You can check the referrer page on page 2 and execute your already existing function tabs to go to second tab. At that time remove id from first tab and add that attribute to the second li. I removed event from tab function and used tabid only.
<ul class="support--items__cards">
