Error on thr page jQuery(...).on is not a function - javascript

I am creating my first yii framework project. I am using cgridview in my project. When I load the page an error is showing in the console. The error is coming from a Javascript code generated by cgridview.
error is
TypeError: jQuery(...).on is not a function
jQuery(document).on('click','#items-grid a.delete',function(){
My javascript is
/*<![CDATA[*/
jQuery(function($) {
jQuery(document).on('click','#items-grid a.delete',function(){
confirmDelete(this);
return false;
});
jQuery('#items-grid').yiiGridView({'ajaxUpdate':['menuitems- grid'],'ajaxVar':'ajax','pagerClass':'pager','loadingClass':'grid-view-loading','filterClass':'filters','tableClass':'items','selectableRows':1,'enableHistory':false,'updateSelector':'{page}, {sort}','filterSelector':'{filter}','pageVar':'items_page'});
});
/*]]>*/
What Kind of issue this is. I have included jquery.js latest vertion in my header. I tried older version also but this error is same. How should I fix this error?

You may need to disable Yii's build-in JQuery and use your own version of JQuery. To disable Yii's built-in JQuery put the following lines into your view and load your own JQuery with avoiding conflicts:
Yii::app()->clientScript->scriptMap=array(
'jquery.js'=>false,
'jquery.ui.js' => false,
);

Resolve the not a function error in the webpage

This is a screenshot of the error from Developer console in browser:
Now, I understand that the error occurs because .suggest() is not a function but it is being called in ajax.js?ver=1.6.5:1287. I don't fully understand what the errors information provided below that means. The lines i etc. Am I supposed to find the .suggest() function in jquery.js?ver=1.12.4-wp:2?
Here is the code from ajax.js:
jQuery(document).ready(function ($) {
$('#wpf_tags').suggest(
window.ajaxurl + "?action=wpforo_tag_search",
{ multiple:true,
multipleSep: ",",
resultsClass: 'wpf_ac_results',
selectClass: 'wpf_ac_over',
matchClass: 'wpf_ac_match',
onSelect: function() {}
}
);
// More code
This is from a WordPress plugin which works fine with the default 2019 theme. However, it throws up the error when I use it with a theme I created. I am loading jQuery version 3.3.1 in the footer of my theme. Can this be the reason for the above error?
Thanks.
UPDATE
I added the plugin to the footer of the webpage but the error still did not disappear. After that I looked at the source code of the page by pressing Ctrl + U. This showed me that the problematic file ajax.js loads on line 102. However, the suggest plugin loads on line 515.
I have no control over the source code on that page because it is generated by the WordPress plugin. How can I load these files in proper order?
Thanks.

JQueryUi Autocomplete Combobox sometimes not loading properly in Firefox

I am using JQueryUi 1.12.1 version and JQuery 3.2.1 version.
I am trying to use 2 JQueryUI Autocomplete Comboboxes in my website, so I copied Combobox code from here, changed it a little bit and added to JS file twice (with widget names 'combobox' and 'combobox2', they have diffrent logic and they are dependent on each other). In latest version of Chrome it's working as intended, but in Firefox sometimes (mostly on first loading of page after closing browser, but if I refresh page constantly something like 1 of 10 tries is ending up with error) I have an error saying:
TypeError: jQuery(...).combobox is not a function.
Here is my js file code:
jQuery(document).ready(
function ($) {
$.widget( "custom.combobox", {
//code...
});
$.widget( "custom.combobox2", {
//code...
});
jQuery('#id_substancename').combobox();
jQuery('#id_casnumber').combobox2();
//code...
});
Changing:
jQuery('#id_substancename').combobox();
jQuery('#id_casnumber').combobox2();
To:
$('#id_substancename').combobox();
$('#id_casnumber').combobox2();
Fixed the problem.

"TypeError: $ is not a function" after loading some scripts into wordpress

We start to provide a HTML-Snippet like Google or Facebook does for its advertising things or the integration for the Facebook like button. It contains a business application.
Our HTML-Snippet loads a script and contains a few more informations:
<div id="ncc" data-hash="" ng-jq>
<div id="wiz" ng-controller="WizardCtrl"></div>
<script src="{{URLTOSCRIPT}}/load.js"></script>
</div>
The script checks if a jQuery is installed and loads all related things into the DOM and at the ends inits an angular-Application.
All this works fine on pages that havn't enabled jQuery.noConflicts-Mode.
After the latest Wordpress-Updates we got an ERROR
"TypeError: $ is not a function"
We tried to get rid of it using some workaroungs like
jQuery(document).ready(function($){
$(function () {
//code to execute
});
OR
jQuery(document).ready(function(){
var j = jQuery.noConflicts();
j(function () {
//code to execute
});
and changed also all references in the angular-part. But nothing working really well.
Any suggestions?
We are using AngularJs v1.4.7, jQuery v1.11.3 (started to migrate to 2.1.4), the
Sometimes when more versions of jQuery are loaded or if it conflicts with another library you can get that error:
have you tried to replace in all of your code the $ symbol with the word "jQuery"?
So your example would become:
jQuery(document).ready(function(){
jQuery(function () {
//code to execute
});
Note: I don't think that in this case passing "$" as a parameter is needed anymore ;)
EDIT: there is also another possibility:
you say that you're using the $ sign (i guess to avoid the usual conflicts in wordpress) in this way:
jQuery(document).ready(function($){
$(function () {
//code to execute
});
But this will make the $ symbol available only inside the ready() function.
Did you check if you have somewhere code using the $ where you actually aren't allowed to (or in other words if you have any piece of your js code where $ isn't mapped as "jQuery")?
EDIT 2: The only working solution in the end was:
(function($,undefined){
$(document).ready(function(){
//code to execute
});
})(jQuery);"
Make sure jQuery is loaded before any other script that uses certain jQuery functions.
Normally those errors arise, when the jQuery library wasn't loaded yet. Make sure that a $()-call is called after jquery was loaded, which normally happens at the end of your file to speed up loading times.
Therefore putting
<script src="{{URLTOSCRIPT}}/load.js"></script>
to the end of the body-tag should help.
Usually when you get this error: "TypeError: $ is not a function"
it means, you a missing a JQuery library or they are not placed in the correct order. Ordering JQuery libraries is important.
$ is not a function. It means that there is a function named $, but it does not have a plugin/widget named selectable. So, something has stolen your $ or there is another library added after it, or it was never loaded.
Your script file is not loading properly or script file is not available.
open browser inspect element and put this code
jQuery().jquery.
it's display which jquery version is use.
this is for testing
jQuery(document).ready(function()
{
alert("test");
});

Anonymous Function Error: $ is not defined

Google Developer Tools is displaying the following error when my PHP page uses the content from a javascript file (my_scripts.js):
"Uncaught ReferenceError: $ is not defined scripts.js:1 (anonymous function)"
Content of my_scripts.js
$('a.button').click(function(){
window.location.href = "another_page.php";
});
The page and the script work as required. Clicking the element links to the requested page, but the error is there.
1) What causes the error?
2) Can it or should it be ignored?
1) It looks like your problem is that jQuery haven't been loaded.
Make sure you load jQuery before scripts.js.
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</head>
2) Errors should never be ignored.
You need to load jquery libary BEFORE! Please download the jquery.min.js at http://www.jquery.com/download/
also, write like this:
$(doucment).ready(function(){
$('a.button').on('click',function(){
window.location.href = "another_page.php";
});
});
If you have already included jQuery on your file, and still its not working you should try,
jQuery(doucment).ready(function(){
jQuery('a.button').on('click',function(){
window.location.href = "another_page.php";
});
});
This is causing as there might be some conflicting js files.

jquery autocomplete this.source is not a function error

I've implemented autocomplete on an input field, but the box does not show up and firebug returns "this.source is not a function". I've used autocomplete on other fields of the same page without any problems. (two textarea's).
I'm using the following code to debug, same effect if I run from script file or Firebug command line.
var fakedata = ['test1','test2','test3','test4','ietsanders'];
$("#omschrijving").autocomplete(fakedata);
running jquery 1.4.2 and jquery ui 1.8.2, both minified versions.
Does anyone have an idea how autocomplete works fine on the textareas but causes this malfunctioning on inputs?
Error & Stack trace:
this.source is not a function
http://facturatie.autodealers.nl/dev/resources/js/jquery-ui-1.8.2.custom.min.js
Line 570
close(Object { name="a"})jquery....min.js (regel 570)
close(Object { name="a"}, Object { name="c"})jquery....min.js (regel 570)
response()
Answer is that the first parameter of the autocomplete should be an object containing the "source" property. This works
var fakedata = ['test1','test2','test3','test4','ietsanders'];
$("#omschrijving").autocomplete({source:fakedata});
If you were trying to use autocomplete from http://www.devbridge.com/projects/autocomplete/jquery/#demo, it now collides with the autocomplete method in jQuery UI. I had the same problem and later noticed that I could just use the jQuery UI implementation.
(NOTE: It appears that this page's documentation is wrong: http://docs.jquery.com/Plugins/Autocomplete#Setup)
If you use it with jQuery UI library it also has plugin named autocomplete. In this case you can use plugin alias devbridgeAutocomplete:
$('.autocomplete').devbridgeAutocomplete({ ... });
This solve the problem with jQuery UI collision
As Shelton stated, the version from devbridge.com (1.1.3) collides with jQuery UI (1.8.4). Got it working by making sure the devbridge version loads after jQuery UI's version.
Had similar problem for tagedit/autocomplete. It seems you also want to disable the autocomplete. Setting the source to false avoids these errors.
Solution:
options.autocompleteOptions.source = false;
Search at the end of jquery.autocomplete.js the following section:
Create chainable jQuery plugin:
$.fn.devbridgeAutocomplete = function (options, args) {....
This devbridgeAutocomplete is an alternative plugin to access to the same functionality using this lines:
if (!$.fn.autocomplete) {
$.fn.autocomplete = $.fn.devbridgeAutocomplete;
}
So.. you can use devbridgeAutocomplete instead of autocomplete or any name by changing this $.fn.devbridgeAutocomplete
in my case I had a second import of jquery which I didn't realize.
Something like:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"> </script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.devbridge-autocomplete/1.2.27/jquery.autocomplete.min.js"></script>
// More code
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"> </script>
So be sure to import the autocomplete script after you initialized jquery.
