This is the updated post. In my original post, I asked to how to trigger a jQuery event. I got 2 solution responses. For an unknown reason, my original post was gone. I have to re-post it. In this update, I revised my coded per one of the response. The jquery function is triggered. However, I could not get my expected result. The related code is below. If I click the link on ht page, Outlook pops out. In this triggered event, Outlook does not pop out even though the jquery function is triggered. In this update, I wish someone can point out what I should do to make the triggered event like a real onclick. Thanks.

Solution 1

You are using class

class="aaf"

and class selector is preceded by a dot.

$('.aaf').click();

learn more: jQuery Selectors[^]
try this:

JavaScript

$('.aaf').on("click", function () {
   alert("U click me");
})

function f1() {
  $('.aaf').click();
}

f1();

Try with below code:

HTML

<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script>

$(document).ready(function(){

	$('.aaf').on("click", function () {
		alert('jsa');
	});
});

function f1() {
	alert('jsa111');
	$('#a1').trigger('click');
}
</script>
</head>
<body>
<p style="margin-removed 0px;" id='p1' >
    <input id="btn2" name="btn2" type="button" value="Submit" onclick="f1()" />
    <a href="#" class="aaf" id='a1'>xxxxxxx</a>
 </p>

</body>
</html>
