To include both href and onclick in an HTML a tag with JavaScript, we add both attributes.
For instance, we add a link with
<a href="www.example.com" onclick="return onClick();">Item</a>
We define the onClick function with
function onClick() {
// ...
}
We set onclick to return the return value of onClick so that if onClick returns false, the link won’t navigate to the href URL.
onClick is called when the link is clicked.
