Uncaught TypeError: in jQuery

Question

I am using confirm dialog of jquery-confirm.js plugin in my project.

but I caught below error :

"Uncaught TypeError: a(...).on is not a function
 at jquery-confirm.min.js:10
 at jquery-confirm.min.js:10"

after a long google I inserted the below jQuery CDN to the to of that function then that confirm dialog of the plugin jjquery-confirm is working fine, but i got an another error:

$() is not a function

the problem is that i have another document.ready() function like below

    $(function() {
    $("#successMsg").dialog({
            modal: true,
            autoOpen: false,
            buttons: {
                OK: function() {
                    $(this).dialog('close');
                }
            }
    });
    $("#failureMsg").dialog({
        modal: true,
        autoOpen: false,
        buttons: {
            OK: function() {
                $(this).dialog('close');
            }
        }
    });

    $("#validateMsg").dialog({
            modal: true,
            autoOpen: false,
            buttons: {
                OK: function() {
                    $(this).dialog('close');
                }
            }
    });
});

Below two jquery path is available on the page

<script src='/scripts/jquery-1.4.2.min.js'></script>

<script
src="https://code.jquery.com/jquery-3.2.1.min.js"
integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
crossorigin="anonymous"></script>

I thought it because of the jquery version i used the below code, but there is no luck

$.noConflict();

The problem I could not able to use both the functions, It would be very much appreciable if any know the solution.

remove one of your 2 jqueries. – Nirav Joshi Jun 23 '17 at 05:49 — Nirav Joshi, Jun 23 '17 at 05:49

You were getting Uncaught TypeError: a(...).on is not a function because you were using jquery version below 1.4.2 in which .on is not supported as it is introduced in version 1.7.

So either change on to bind with jquery version 1.4.2

or keep on as is and use latest jquery version i.e. cdn one.
