I'm using bootstrap 5 i have one modal for login and register but but there is two bootstrap tabs inside one modal and i want to display tab as per button click but this is not working.
When i click on login button then inside modal login tab should be active and if i click on register button then inside modal register tab should be active.
Giving this error in console:- Uncaught TypeError: Cannot read property 'show' of null
My Code:
$('.register-btn').click(function() {
$('#loginModal').modal('show');
var triggerEl = document.querySelector('[data-bs-target="#register"]')
bootstrap.Tab.getInstance(triggerEl).show()
})
$('.login-btn').click(function() {
$('#loginModal').modal('show');
var triggerE2 = document.querySelector('[data-bs-target="#login"]')
bootstrap.Tab.getInstance(triggerE2).show()

Reset to default 5Gives me an error : bootstrap.Tab.getInstance(...) is null –
It's necessary use getOrCreateInstance instead of getInstance
https://getbootstrap./docs/5.2/ponents/navs-tabs/#methods
You can trigger the click to simulate clicking the tab.
$(".register-btn").click(function () {
$("#register-tab").trigger("click");
$("#loginModal").modal("show");
});
$(".login-btn").click(function () {
$("#login-tab").trigger("click");
$("#loginModal").modal("show");

</div>You need to 1) Enable tabbable tabs via JavaScript, and then 2) Activate individual tabs (the triggers you're trying to refer to don't exist).
https://getbootstrap./docs/5.0/ponents/navs-tabs/
Check: Via JavaScript
// Via JavaScript
// Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
var triggerTabList = [].slice.call(document.querySelectorAll('#myTab a'))
triggerTabList.forEach(function (triggerEl) {
var tabTrigger = new bootstrap.Tab(triggerEl)
triggerEl.addEventListener('click', function (event) {
event.preventDefault()
tabTrigger.show()
})
})
// You can activate individual tabs in several ways:
var triggerEl = document.querySelector('#myTab a[href="#profile"]')
bootstrap.Tab.getInstance(triggerEl).show() // Select tab by name
var triggerFirstTabEl = document.querySelector('#myTab li:first-child a')
bootstrap.Tab.getInstance(triggerFirstTabEl).show() // Select first tab
