Several ways of blocking event bubbling in jquery and its difference introduction

What is the blocking event bubbling method in jquery? This article has prepared two ways to prevent event bubbling, the difference between the two ways. Return false not only prevents the event from bubbling up, but also prevents the event itself

JQuery provides two ways to block event bubbling.   Mode one: Event.stoppropagation ();  The code is as follows: $ ("#div1"). MouseDown (function (event) {event.stoppropagation ();    });  Mode two: return false;  The code is as follows: $ ("#div1"). MouseDown (function (event) {return false;    }); But there is a difference between these two ways.    Return false not only prevents the event from bubbling up, but also blocks the event itself. Event.stoppropagation () only blocks the event from bubbling up and does not block the event itself.
