Conflict in code between two JS Libraries - javascript

I'm trying to use two different libraries on a single webpage -- Materialize.css and JQuery EasyUI -- but their code seems to be interfering with each other and I'm running into errors. Is there any way I could ensure their codes do not conflict with each other and each run separately?
I guess using an iframe could be a solution here, but that would introduce other problems for me. Is there any other way I can ensure they both run on the same page in harmony?
EDIT: I should point out that I'm using the functionalities of each of of the libraries in two different sections of the page. More specifically, the Materialize.css is used for the navbar, text and the general look of the page whereas I'm using JQuery EasyUI just to display an editable datagrid.

Typically it is impossible to prevent conflicts between libraries that you yourself do not write/manage. If they don't have a means of preventing a conflict (like jQuery's jQuery.noConflict()), you just have a problem, except if you use module bundlers like Webpack which enables to load modules under different aliases so that they don't conflict.

Materialize and jQuery both use the $ prefix. Instead of using $.noConflict();, try assigning jQuery to a new variable as a prefix:
var jq = $.noConflict();
Then you'll be using jquery with the variable name as prefix, ex:
jq("div").click(function(){
//do something
});

Could I use an old Javascript file with a new CSS file in Materialize?

This is my short problem, in my page I have an old version of Materialize, and I have seen in the last version of it that they have added the class "xl" to define grid's sizes.
If I upgrade all files, my page will break, because for example, in my JS file I open the modals with the function "leanModal()" and in the new version they use "modal()" and if I upgrade it, is a lot of time!!.
My questions is the next:
If I only need the class "xl" can I upgrade only the CSS File? If I would make it, would have a problem in the future with the JS File?
My version of Materialize: v0.97.7 (2014-2015)
The actual version of Materialize: v0.98.1 (2017-Now)
I'm not all that familiar with Materialize but I believe it has components that are implemented with a mix of CSS, HTML and JS. If you are using any of these components then yes, there's a possibility that other things might break. Typically these components will be expecting a certain HTML structure and CSS classes to be available/used. If the name of something has changed in one area of the framework then it's reasonable that something else could have changed elsewhere. You'd have to verify that yourself.
Yes, You will have problems because the JavaScript calls specific classes in the CSS for that version.

Calling specific jQuery plugin functions, where two plugins have the same function name

I am working on a project where I am using Twitter Bootstrap Framework. I am also using the jQuery UI library. The problem is that in these two libraries there are a few functions with the same name, eg tooltip. Now when I apply this function to any element, the function with the last declaration is being applied.
For example if I include the jQuery UI library after the Bootstrap library, and use
$("element").tooltip();
The tooltip() function in jQuery UI is called. I know I can achieve the desired result by removing the given function from one of the library or by rearranging the position of libraries. But I wanted to know whether there is any way to specify which library's function is to be called when there are two libraries sharing the same function name.
No there is no way to use both functions at the same time. Both functions are added into $() Object through prototype. So maybe you should rename one of this, or use only one.
You can rename one plugin after it is loaded, and before you load the next one. Something like $.fn.jqueryui_tooltip = $.fn.tooltip; and only then load Twitter's library.

Javascript errors in my Joomla website

my website is marutiindia.in. My website was working fine until I installed a module named lof k2 scroller. The website was showing jquery errors and the module at the lower half of the template was not working. But I managed to get the module to work by adding the following code at the start of the JS file which was showing error:
if(jQuery){
jQuery.noConflict();
}
But, now I am getting other JS errors which I am not able to understand.
Below is the link for the screenshot of errors:

I don't know what these errors mean.
Also I have one more plugin to use for my website which also causes scroller to not work.
Please help me resolve these errors.
Thanks.
Joomla uses Mootools, which also use the $ function name. in order to avoid this, your plugins either:
must use jQuery instead of $. For example, instead of $('div') to get divs, use jQuery('div')
if you really want to use $, wrap the jQuery code in a closure
(function($){
//code that uses `$`
}(jQuery))
make sure the plugins are extending from jQuery and not $.

Combining Multiple jQuery Scripts

I'm trying to create a simple portfolio site for a friend of mine based around his drawings and paintings. The layout is relatively simple but is proving to be very difficult to implement. I have three jquery scripts on the page that each perform a specific function.
1) bgStretcher - Stretches a series of background images to fill a user's window.
2) collapse - Simple collapsable menu system
3) galleryview - Basic no frills slideshow gallery
Currently, bgstretcher and collapse are on one page called nav.shtml (http://yungchoi.com/nav.shtml) and the gallery on gallery.shtml(http://yungchoi.com/gallery.shtml). Seperatley they work fine, but when I call the nav page via SSI (test.shtml), The code seems to run into problems and becomes disabled.
The solutions I've found all lead to utilizing the noConflict function in jquery (http://stackoverflow.com/questions/2656360/use-multiple-jquery-and-jquery-ui-libraries), (http://hubpages.com/hub/How-to-use-jQuery_noConflict), but everytime I've tried inserting it and changing my code, everything gets messed up again. I've also organized each script's files into separate folders and directories but that hasn't helped either.
My experience is in graphic and web design, so my coding skills are not the greatest. I do know the basics, but rewriting jquery code was not something I ever learned so I might not be understanding how to correctly fix this problem. If someone could clearly and easily explain what I would need to do to make these all work together, I'd appreciate it greatly.
Thanks!
You still have multiple versions of jQuery being loaded in your page.
Remove:
<script type="text/javascript" src="support/bgstrecher/jquery-1.3.2.min.js"></script>
and
<script src="support/collapse/jquery-1.2.1.min.js" type="text/javascript"></script>
you should also remove:
<script type="text/javascript">
$.noConflict();
// Code that uses other library's $ can follow here.
</script>
& - (because you only need either the packed or unpacked version, not both)
<script type="text/javascript" src="galleryview/jquery.galleryview-2.1.1.js"></script>
See if that helps.
You only need noConflict if you're going to also use other libraries that are similar to jQuery like MooTools, Dojo or Prototype. It's unlikely you will need to & if you do, you will need to recode to use the jQuery function instead of the $.
The issue it appears you're having is that all these jQuery includes are overwriting the previous version of jQuery which the plugin attached to and thus the function no longer exists when you call it.
Why are you loading Jquery twice ?
First the 1.4.2 min file and then the full blown straight after ?
You still have multiple calls to jQuery (even if files are not in same directories).
In the same way, you call "galleryview/jquery.galleryview-2.1.1.js" twice (the second file is just packed).
By the way, my error console tell me that:
"Error: jQuery.timer is undefined
Source File: http://yungchoi.com/galleryview/jquery.timers-1.2.js
Line: 135"
Are you sure you need this timer plugin? For now, it seems you have too many script included. Try to remove all unneeded files (you should keep only one version of jquery. But if some plugins you used is not compatible with, you'll have more and more compatibility problems).

Fancybox is not a function

Hello I am using the jQuery plugin fancybox to display bing maps when somebody enters an address into a textbox and hits the submit button beside it. And a fancybox is loaded and a map for that address is displayed. This is working well with my application, but the problem is, it is only working well on one page and on the other one, when I load it, it is giving me an error saying fancybox is not a function. I get to see this error in the error console and in the firebug console. I am not sure what could the problem. The same code works in another page, but it doesn't on this one?
$("Map").fancybox is not a function
I am pretty sure it is not re-usability issue. But when I test to see if fancybox's original files have been loaded, they are loaded with the dom, so it might not be actual problem. But I am unable to understand what else could the problem be.
This is my code
abbr: is just a text bit. I have different divs based on what the user selects. And each div would have its own controls, which would start with that text and are appended with their own definitions such as mapresults, decValLat, decValLon etc.
ex: abbr>>east
and then the ids would be eastmapresults, eastdecValLat, eastdecValLon etc.
function showMapFancybox(abbr){
var abbr;
$('#'+abbr+'mapresults').hide();
$('Map').fancybox({
overlayShow: true,
onClosed: function() {
$('#'+abbr+'mapresults').show();
map_latdec = $('#decValLat').attr('value');
map_longdec = $('#decValLon').attr('value');
map_latdeg = $('#degValLat').attr('value');
map_longdeg = $('#degValLon').attr('value');
$('#'+abbr+'decValLatsub').val(map_latdec);
$('#'+abbr+'decValLonsub').val(map_longdec);
$('#'+abbr+'degValLatsub').val(map_latdeg+'N');
$('#'+abbr+'degValLonsub').val(map_longdeg+'W');
}
}).click();
};
I already had this type of errors because i was reloading jQuery after the plugin import, check you don't reimport jquery by mistake (sometimes included in a package like jQuery tools).
I just had this issue, it seem some versions of jQuery are not compatible with versions of FancyBox, for example Fancybox 1.3.4 is buggy with jQuery versions below 1.7 and doesn't work on version higher than 1.8.
Possible Solutions:
1) have you already loaded jQuery? If not, then load it before any $ commands start.
2) Check, probably you are loading jquery library (.js) several times during the page. Try to load only one.
3) In the end of file, you can execute this javascript command: $ = jQuery.noConflict(); and it might solve. If not, then anywhere use the word jQuery instead of $, and it will work too.
You need to load the extensions like easing.js and mousewheel.js BEFORE the main fancybox plugin. That solves the problem.
If "fancybox" as a function does not exist, it is likely that either the jQuery source or the plugin source are failing to load into your page. Make sure that the pathing, file names, and extension are all correct.
EDIT: Make sure that you link to jQuery Source before you link to any plugins. If a plugin is loaded into your HTML before jQuery is, the plugin fails.
In my case it was jQuery.noConflict(); row in another jQuery plugin ... when I removed everything started to work.
If you are using a plugin which includes JQuery into your header tag, this trouble can arise.
I recently added 'TheThe Slider' to my blog, all my FancyBoxes stopped working. There are easy fixes for this situation though. basically, go to the plugin directory, search for the call to jquery and make it's usage conditional. If you would like to see my implementation of this I did blog about it with screen-capture.
I got this issue in my WordPress web site and I found the issue was happening due to fancybox.js presenting twice in the code from two plugins which I installed. So check your code and make sure to load from one source.
