No CSS and JS loading on Wordpress site after enabling plugin - javascript

Quick question: as someone who is using Wordpress a lot, I am first time ever noticing that I can't see any Javascript files associated with my plugin (ULike plugin) on my website when I enable that specific plugin. The HTML is loaded, but CSS and JS files are entirely missing and thus not loaded on the page...
I ran out of options. I already removed cache, enabled debug mode in Wordpress (didn't give any errors), checked the console and logs...
Any idea what might cause this error and what else I can do to check what is going wrong?

It might be an error with your URL ( www ) while loading CSS and JS.
Fixing all the links of CSS and JS should work.

I have an answer to my own question. It was because <?php wp_head() ?> was not added in my header.php that is was not working.
Problem solved!

Is there a function to prevent a JS file from loading in Wordpress?

I'm currently running a Wordpress website and i'm trying to get the best results in terms of speed/score in pageinsights. However, there are a few scripts that keep on loading !
I was wondering if there is a way to prevent this exact file from loading in the page, is a such thing possible ?
Thank you
To answer your question, yes, there is a function in Wordpress to disable script. Kindly see the link: https://developer.wordpress.org/reference/functions/wp_deregister_script/

Js and wordpress help...where does it go?

So ive been putting off using js for a while because everytime I try to figure it out I get more confused, but now I really need it for a site im working on...
I want to hide the page until everything loads (so you don't see elements moving/jumping into place.
I've found various bits on here and around the web, but everytime I go to place the code anywhere that I feel it should go, I get errors.
take this for example:
window.onload=function() {
document.getElementById('loading-mask').style.display='none';
}
Ive tried going to the functions.php file and adding the js code i've found on the web but always get an error. So where do I copy the code for this, so it affects the CSS ive added?
In wordpress, you need to use a plugin to help you insert your javascript/jquery
Login to wordpress
Go to plugins>>add new
Search for Insert Headers and Footers plugin
Install and activate
Then launch the plugin and insert your javascript.
You will need to select the location of your javascript, either in the tag or just before the closing
When you add javascript to a wordpress website, you want to do it in one of two ways. You can either do it using a hook which is essentially a 'spot' in the code you wish to add to.
This can be done by placing the following in your functions.php
add_action('wp_head', 'wp_54885300_add_js_to_header');
function wp_54885300_add_js_to_header(){ ?>
<script>
window.onload=function() {
document.getElementById('loading-mask').style.display='none';
}
</script>
<?php
}
Alternatively, if you find yourself needing to place lots of javascript into your website, you may wish to link to an external javascript file. This can be done with wp_enqueue_script().
Place the following in your functions.php file to enqueue an external stylesheet to your website.
add_action( 'wp_enqueue_scripts', 'wp_54885300_enqueue_script' );
function wp_54885300_enqueue_script(){
wp_enqueue_script('anyname', 'path-to-file.js', array(''), 'version', false );
}
As others have pointed out, what you are trying to do by hiding everything until the window has completely loaded may not be a good idea for a number or reasons.
But, atleast to the best of my knowledge, this ^^ is the proper way to include JS into a wordpress installation without depending on a plugin to get you started.

How do I force jQuery to load first?

I am trying to add bootstrap-select to my Flask app and I keep running into the error "TypeError: $(...).selectpicker is not a function". Everything I've read says this only occurs if you load jQuery again after loading bootstrap-select.js, so I went through and cleaned up my scripts, ensuring that jQuery was being loaded before all my other JS scripts, like so:
<script src="http://code.jquery.com/jquery-1.12.4.min.js" integrity="sha256-ZosEbRLbNQzLpnKIkEdrPv7lOy9C27hHQ+Xp8a4MxAQ=" crossorigin="anonymous"> </script>
...
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.1/js/bootstrap-select.min.js"></script>
However, I was still getting the same problem. I decided to take a look at the order of loading in the chrome developer tools window, and now I think my problem is this: jQuery is being queued for loading before bootstrap-select, but it's not actually starting the download until after bootstrap-select has already finished. I suspect this is because of the difference in size between the two.
Is there any way I can force my other scripts to delay loading until after jQuery has already loaded? Or if I figure out how to cache a copy of jQuery in my static directory, will that help?
Edit: Wow, okay, I got a lot of comments on this! To try and clarify as much as possible, I'm just going to make some notes:
After thoroughly checking all my scripts, I can confirm that only one copy of jQuery is being loaded.
This is not an https page, I'm running it locally on a Flask development server.
I checked the bootstrap-select url I have in my code and it is the correct one. Sorry, I'm not sure why it left out the dash when I was copy-pasting. I have corrected the question accordingly.
I have been using the Network tab in chrome's dev tools to check loading successes/times.
I moved my jQuery to the very beginning of the file to ensure it would load first, and I can now confirm it is finished loading before bootstrap-select loads.
Despite all this, I'm continuing to get the same error, so if anyone has other suggestions I would appreciate them. I'm completely out of ideas at this point.
You should put defer at the end of both script tags, so they are loaded in order no matter what, like this:
<script src="http://code.jquery.com/jquery-1.12.4.min.js" integrity="sha256-ZosEbRLbNQzLpnKIkEdrPv7lOy9C27hHQ+Xp8a4MxAQ=" crossorigin="anonymous" defer></script>
...
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrapselect/1.13.1/js/bootstrap-select.min.js" defer></script>
Try changing the URL for your bootstrap select library to:
https://cdnjs.cloudflare.com/ajax/libs/bootstrap-select/1.13.1/js/bootstrap-select.min.js
I have the solution and it's dumb as heck.
I was adding my scripts to the same place the previous developer added theirs, in the base template that all my other templates extend. The thing is, they added theirs to the end of the page, after the body tag was closed (presumably to make page loading faster). The little bit of jQuery which was using selectpicker was in the body, and was thus trying to load the function prematurely.
Thanks for all your answers!

JavaScript file(jQuery steps) not loading in Google Chrome

I am using a jQuery plugin the file name is jquery.steps.js.
I include it in index.html unambiguously but Chrome will not load this script. It was somehow in the cache earlier which is why I never noticed this.
Can anyone suggest what the problem might be and how in the world I can get it to load.
Thanks in advance
Im not sure why you are getting that problem but you could solve it adding
'?whateverHere'
at the end of your src attribute of the script, that will enforce the script to be loaded again.

jQuery tabs is loaded but not working in WordPress

I am trying to work with jQuery UI tabs in WordPress but I keep getting the "jQuery("#").tabs is not a function" error.
I thought the tabs file might not be loading but looking in firebug it shows it is loading. I am also using modernizr so I thought there might be a conflict with that but using jQuery.noConflict(); did not solve the problem either. At first I used to load jQuery but for some reason it wouldn't work. Now I just linking directly to the files and they are loading.
If it helps, I am trying to get tabs working for this tutorial. The website I working on is lbk.newcoastmedia.com/wordpress
Thanks for any help!
I see the following scripts being loaded on your page:
modernizr-1.6.min.js
l10n.js
jquery.js
galleria.js
and
<script type="text/javascript">
jQuery(document).ready(function($){
$("#photo-rotator").tabs({fx:{opacity: "toggle"}}).tabs("rotate", 4000);
});
</script>
$.tabs is an extension of jQuery UI, and I don't see jQuery UI or the tabs extension loaded on your page. Look at the very bottom of the source at your link and you'll see the following two scripts, which I believe are what you're missing.
ui.core.js
ui.tabs.js
Your debugger is alerting you that $.tabs is not a method because it really hasn't been defined yet.
Just had this problem on Drupal and resolved it by downloading a custom build of the jQuery UI library WITH Tabs selected. Apparently the default jQuery UI library that shipped with Drupal didn't have this module, so perhaps this is also the case with WP.
