I have a link on a web page. When a user clicks it, a widget on the page should update. However, I am doing something, because the default functionality (navigating to a different page) occurs before the event fires.
This is what the link looks like:
<a href="store/cart/" class="update-cart">Update Cart</a>
This is what the jQuery looks like:
$('.update-cart').click(function(e) {
e.stopPropagation();
updateCartWidget();
});
What is the problem?

I've just wasted an hour on this. I tried everything - it turned out (and I can hardly believe this) that giving my cancel button and element id of cancel meant that any attempt to prevent event propagation would fail! I guess an HTML page must treat this as someone pressing ESC?
This code strip all event listeners
var old_element=document.getElementsByClassName(".update-cart");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);
You can use e.preventDefault();
instead of e.stopPropagation();
$('.update-cart').click(function(e) {
updateCartWidget();
e.stopPropagation();
e.preventDefault();
});
$('.update-cart').click(function() {
updateCartWidget();
return false;
});
The following methods achieve the exact same thing.
You want e.preventDefault()
to prevent the default functionality from occurring.
Or have return false
from your method.
preventDefault
prevents the default functionality and stopPropagation
prevents the event from bubbling up to container elements.
