javascript - Simulate a click event (tap with finger) on a button in iOS

Question

I'm trying to write a script that adds an item to the cart by simulating a click on the add-to-cart button on a webpage

<span id="cart-update">
<span class="cart-button">add to basket</span>
</span>

When I try to do the following on desktop, it works perfectly

document.getElementById('cart-update').click();

But when I try doing the same thing on iPhone it doesn't work. I tried using the advice from this answer ( Simulate click event on mobile device ) and it didn't seem to work. Can you help me out?

Answer 1

Have you tried monitoring touch events at all, instead of click events? Mobile browsers have their own events they're monitoring, some not considering "click" as an event at all

From: https://developer.mozilla.org/en-US/docs/Web/API/Touch_events

function startup() {
  var el = document.getElementsByTagName("button")[0];
  el.addEventListener("touchstart", handleStart, false);
  el.addEventListener("touchend", handleEnd, false);
  el.addEventListener("touchcancel", handleCancel, false);
  el.addEventListener("touchmove", handleMove, false);
  console.log("initialized.");
}

A way to work around it would be for a click/touch event to trigger a separate function entirely, like calling handleStart() in your function triggering the click event. Might be a better separation of concerns, too.
