I am trying to get my document.on function to work when the user clicks on the p tag that has a class called card. So far the function is non responsive. What should I change so the function will respond when I click on the p tag that has a class called card. Here is my HTML and JQuery code.

<!DOCTYPE HTML>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="description" content="Contacts">

    <script type="text/javascript">
    $(document).ready(function(){

        $('button').click(function(){
            var first = $('input.first').val();
            var last = $('input.last').val();
            var desc = $('textarea').val();

            $('div.right').append("<p class='card'><h1>"+ first +' '+last+"</h1><h4>'Click for description!'</h4></p><p class='back'>"+desc+"</p>");

            return false; 
        });

        $(document).on('click', 'p.card', function(){ //this is the function I am trying to get to work.  
            alert("test");
        });

  • Please make sure the jquery library path is correct or not? – Sudharsan S Commented Dec 22, 2016 at 5:03
  • Tell me which jquery versiion you are using? – Sudharsan S Commented Dec 22, 2016 at 5:03
  • @SudharsanS, I am using version three and my jquery path works. I tested it – Aaron Commented Dec 22, 2016 at 5:07
  • Using developer tools inpsection, you'll see your added html is <p class="card"></p><h1> </h1><h4>'Click for description!'</h4><p></p><p class="back"></p> ... so the p.card is empty, very hard to click ... looks like jQuery append is dumber than dishwater – Jaromanda X Commented Dec 22, 2016 at 5:09

Reset to default 3

Somehow the p.class you were appending was broken, it was below the other elements and was not being identified as the sender by jQuery event.

The following works fine:

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>

        <script type="text/javascript">
        $(document).ready(function(){

            $('button').click(function(){
                var first = $('input.first').val();
                var last = $('input.last').val();
                var desc = $('textarea').val();
                var p = $('<p class="card">');
                p.append("<h1>"+ first +' '+last+"</h1><h4>'Click for description!'</h4><p class='back'>"+desc+"</p>");
                $('div.right').append(p);
                return false;
            });
          
            $(document).on('click', 'p.card', function(){ //this is the function I am trying to get to work.  
                alert("test");

your code were not right , the appending elements not formatted as your wish , thats why the click function not working, check the below snippt i have fixed your code, hope fully this will help you 

$(document).ready(function(){

	$('button').click(function(){
		var first = $('input.first').val();
		var last = $('input.last').val();
		var desc = $('textarea').val();

		$('div.right').append('<p class="card"></p>');
			$('.card').html("<h1> first +' '+last</h1><h4>Click for description!'</h4><p class='back'>+desc+</p>"
		);
			
	});

	$(document).on('click', 'p.card', function(){ //this is the function I am trying to get to work.  
		alert("test");

	});
});

looks like You're misusing the header tags.

I tried your DOM structure, and what's happening is that when Firefox/Chrome sees an invalid <h1> tag inside the <p>, it automatically closes the <p> tag. You can clearly see this in Developer Tools.

You should use <span> tags instead of header tags, check this it Works here

JS CODE:

 $('div.right')
 .append('<p class="card"><span>'+first+'<==>'+last+'</span>Click for Description!!!</p>');

Using developer tools inpsection, you'll see your added html is 

<p class="card"></p><h1> </h1><h4>'Click for description!'</h4><p></p><p class="back"></p>`

No matter what I've tried, I can't get Firefox to create insert that html as you want it!! it's like it doesn't want to put h1/h4 inside a p so decides to close the p early!

change to

$('div.right').append("<div class='card'><h1>"+ first +' '+last+"</h1><h4>'Click for description!'</h4></div><p class='back'>"+desc+"</p>");

and it all goes good - indeed, it's odd, that you already have css for div.card, but not p.card!!

You could do it in Javascript and impliment jquery in the function:

var div = document.getElementById('someid');
function foo(e) {
    //Jquery Here
}
div.addEventListener('click', foo);

This is what I use for a lot of my functions.

Wrap card with <div/> instead of <p/> and it should work. As you have other block elements inside <p/>. It's breaking your html.

$('div.right').append("<div class='card'><h1>"+ first +' '+last+"</h1><h4>'Click for description!'</h4><p class='back'>"+desc+"</p></div>");

And then change 'p.card' to 'div.card'.
