How we can prioritize jQuery events?
To prioritize jQuery events, use the event.stopPropagation().
Example
You can try to run the following code to learn how to prioritize using stopPropogation() method:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var timer;
function out(s) {
if (timer) {
clearTimeout(timer);
timer = null;
}
$("#demo").append(s + "<br>");
timer = setTimeout(function() {
$("#demo").append("-------" + "<br>");
timer = null;
}, 100);
}
$(".li").find('input').click(function(e){
out('li>input');
if ($(this).parent().hasClass("stop")) {
e.stopPropagation();
}
});
$(".li").click(function(e){
out('li');
});
$('input').click(function(e){
out('input');
if ($(this).parent().hasClass("stop")) {
e.stopPropagation();
}
});
});
</script>
</head>
<body>
<ul>
<li class="li"><input type="checkbox" /><span>Demo</span></li>
<li class="li stop"><input type="checkbox" /><span>Demo using stop propagation method</span></li>
</ul>
<div id="demo"></div>
</body>
</html>
