How to get event in liquid when product quantity is changed in PDP and cart page ???

Hi @Amith_M, what do you mean? In Shopify’s Liquid templating language, there is no built-in event listener for changes in product quantity. You can use JavaScript to do it dynamically.

For example:

document.addEventListener("DOMContentLoaded", function () {
    const quantityInput = document.querySelector('input[name="quantity"]');

    if (quantityInput) {
        quantityInput.addEventListener("input", function (event) {
            console.log("New quantity: ", event.target.value);
            // You can trigger any custom function here
        });
    }
});

Thank you. I was searching for the answer in the doc.
