What you just saw when you dragged a UI element into the search bar. This happens because web developers really like to use the HTML <a> element for buttons instead of the actual <
button> element. You can give the element functionality by listening for its click event and doing things then, but the <a> element is intended for creating hyperlinks and as such won't work without a set href attribute (AKA the
link that you are taken to when you click on it). Therefore, you can use the void JavaScript operator, which will return the value undefined. If the browser is told to go to undefined, it will just keep the current page open. void will also evaluate its operands first, so <a href="javascript:void(alert('you clicked me'))">click me</a> would show "you clicked me" when clicked, but most
people would just use javascript:void(
0) and alert "you clicked me" on the click event, as said before. Urban
Dictionary uses the javascript:void(0) technique for some of its UI elements, so when you just dragged the browse (or categories, or
cart)
button into the search bar, and I know you did, its href attribute was copied into the search bar, and now you'
re looking at javascript:void(0) and contemplating your
life choices.
guy 1: god
fucking damn it i just dragged a ui element into the search bar and searched for javascript:void(0), thats so annoying why does it even happen
guy 2: it happens because
people cant use the <
button> element and have to use <a> for some reason
