You are disabling the default function of the click event by returning false on click.
for example :
<a id="btn_save" href="http://www.google.com" onclick="return false;" title="">Save</a>
Even though the points to google.com, when you click the link , it won’t take you to google.com. i.e. the default action is returned false.
It’s similar to event.preventDefault()
solved where does the return of onclick=”return false” go? [duplicate]
