my add to cart button is not responding. I have applied javascript on my add to cart button, In the cart button, I have assigned attribute i.e data-product the value that is {{product.id}}.
var updateBtns = document.getElementsByClassName('update-cart')
for (var i = 0; i < updateBtns.length; i++) {
updateBtns[i].addEventListener('click', function() {
var productId = this.dataset.product
var action = this.dataset.action
console.log('productId:', productId, 'action:', action)
})
}<div class="card-body">
<h5 class="card-title fw-bold text-uppercase">{{product.name}}</h5>
<p class="card-text">
<h4 style="font-size: 1rem; padding: 0.3rem;
opacity: 0.8;">$ {{product.price}} </h4>
</p>
<button data-product={{product.id}} data-action="add" class="btn btn-outline-secondary add-btn update-cart">ADD TO CART</button>
</div>
</div>The console is not showing anything even though I click on Add to Cart button several times
Instead of getElementsByClassName use querySelectorAll beacuse as @tacoshy stated getElementsByClassName returns an object of HTML Collection not an array. Also length would return the amount of elements within an array but not an object.
const updateBtns = document.querySelectorAll('.update-cart')
updateBtns.forEach((updateBtn) => {
updateBtn.addEventListener('click', (event) => {
var productId = updateBtn.dataset.product
var action = updateBtn.dataset.action
console.log('productId:', productId, 'action:', action)
})
})
