i have this javascript that I called cookiebar.js, it shows a sticky bar message for cookies, (source code)

I load it in this way in functions.php in Wordpress:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
It works fine.
Now i duplicate the same javascript code and i called it stickybar.js. I add some modifications, also change class with name "stickybar":
The code of the stickybar.js is here (i pasted it in jsfiddle because there is too much text for stackoverflow)
Then i show this second bar (stickybar.js) only on mobile device and after 8 second with this CSS:
.stickybar { display: none; }
#media only screen and (max-device-width:480px) {
.stickybar {
display: block;
animation: cssAnimation 0s 8s forwards;
visibility: hidden;
}
#keyframes cssAnimation {
to { visibility: visible; }
}
}
I load it in Wordpress with this code in functions.php:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
It works fine.
If i load one by one of this codes, they work fine.
The problem is that when i load the two scripts together in this way in functions.php, only the first works:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
How can i load the two scripts together?
The comment thread on this question is semantically correct, you can only have one instance of each html id attribute, they must be unique, and your find_script_by_id methods are both searching for the same thing.
However, you're doing what's generally called "baking in" the scripts into your header which is at best, a faux pas, at least as far as WordPress is concerned. Properly Enqueueing Scripts (and styles) is very easy in WordPress, and your future self, web clients, and other people who look at your code will thank you for doing it.
It's not unlike how you're "baking in" the scripts now:
function wpb_hook_javascript() {
?>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/cookiebar.js"></script>
<script defer type="text/javascript" id="cookiebanner" src="https://www.examplesite123.com/stickybar.js"></script>
<?php
}
add_action('wp_head', 'wpb_hook_javascript');
But with a few things changed:
function enqueue_my_scripts(){
wp_enqueue_script( 'cookie-bar', 'https://www.examplesite123.com/cookiebar.js', array(), '1.0', true );
wp_enqueue_script( 'sticky-bar', 'https://www.examplesite123.com/stickybar.js', array(), '1.0', true );
}
add_action( 'wp_enqueue_scripts', 'enqueue_my_scripts' );
Namely, it uses the wp_enqueue_script() function on the wp_enqueue_scripts hook. This lets you defer the script to the footer, load in the header, add version numbers to prevent caching issues, add dependencies, allows you to dynamically add/remove them programatically,gives them unique ID's based on the handle, and much more. (You do still need to update your find_script_by_id functions to use these new handles instead cookie-bar, sticky-bar, change the global_instance_name, etc. (more on that in a second)
With that said, if the .js files are on your server, you'll want to use site_url(), plugins_url(), get_stylesheet_directory_uri(), or similar functions to grab the URL of the file instead of typing it out. If you're using a remote resource, don't worry about it, but if they're on you're site, you should swap out the baked in version for that so you don't have issues if you ever move your site, and it allows you easier methods to edit the version to prevent caching problems if you change them.
Back to your variables, you may also want to replace your find_script_by_id type functions with document.currentScript instead, to allow them to be more abstract and not rely on typo/duplicate prone element IDs, and instead reference the currently running <script> tag.
I am trying to implement a fancy slider from codepen in wordpress. I have correctly added the script using the enqueue script method. I know I did it coorectly because it worked for a very small experiment I tried. Now the pen is: http://codepen.io/suez/pen/wMMgXp .

The javascript code can e found above and in the mentioned link.I know that in wordpress we have to use jQuery in place of $ but I still can't seem to figure out how to do it in this case. And one more thing, the css is in scass form but I have taken the compiled css form but I don't think that is causing any problem (rignt?) Everything I have tried till this point has failed. Any help will be appreciated
You can use $ instead of jQuery in WordPress so long as you wrap all your code inside the following:
(function($) {
// Your code goes here
})( jQuery );
If the code is in the header (before the document is ready) then instead use:
jQuery(document).ready(function( $ ) {
// Your code goes here
});
If your code is still having problems, then please include both the enqueue code in your theme and the error messages
I found a new problem where when i manipulate the dom using jquery. The dom is not updated.
Here we go.
var PostCard = function($root) {
this.$root = $root;
this.stuff_id = this.$root.data('stuff_id');
this.id = this.$root.data('id');
this.is_owner = this.$root.data('is_owner');
this.$propose_button = null;
this.$favorite_button = null;
this.init();
this.initEvents();
};
PostCard.prototype.init = function () {
this.$propose_button = this.$root.find("." + PostCard.prototype.CSS_CLASSES.PROPOSE_BUTTON);
this.$proposal_box_modal = this.$root.find("." + PostCard.prototype.CSS_CLASSES.PROPOSAL_MODAL);
this.$proposal_box = this.$root.find("." + PostCard.prototype.CSS_CLASSES.PROPOSAL_BOX);
this.$favorite_button = this.$root.find(".post-card-button-favorite");
this.$total_favorite = this.$root.find('.post-card-total-favorite');
this.$image_view_editor = this.$root.find("#" + this.id + "-image-view");
this.image_view_editor = new ImageViewEditor(this.$image_view_editor);
this.proposal_box = new HomeProposalBox(this.$proposal_box);
};
PostCard.prototype.initEvents = function() {
var self =this;
$(document).on("click", "#" + this.id,function(e) {
if(e.target && $(e.target).hasClass('post-card-button-propose') ){
if(self.is_owner ) {
return false;
}
if(CommonLibrary.isGuest()) {
return false;
}
self.$proposal_box_modal.modal("show").load($(this).attr("value"));
} else if(e.target && $(e.target).hasClass('post-card-button-favorite')) {
self.clickFavoriteButton_();
}
});
PostCard.prototype.clickFavoriteButton_ = function() {
this.markFavorite();
};
PostCard.prototype.markFavorite = function() {
this.$favorite_button.addClass('post-card-button-red');
};
When Favorite button is clicked, the clickFavoriteButton() will be trigerred, and markfavorite method will be fired next.
The problem is although this.$favorite_button is updated (the class is added to the variable), the dom in the page is not updated
this only happens to dynamically loaded element, and does not happen to element that has been around since the page is loaded.

When you scroll the page, the retrieveWhenScroll method will be fired and PostCard will be dynamically added
Trying to auto format some HTML in CodeMirror V4. Found the docs on how to do it but it looks like the call editor.autoFormatRange(range.from, range.to) was removed in V3...
Code for V2 is below.
Anyone know how to do it with V4 today?
From: http://codemirror.net/2/demo/formatting.html
<script>
var editor = CodeMirror.fromTextArea(document.getElementById("code"), {
lineNumbers: true,
mode: "htmlmixed"
});
CodeMirror.commands["selectAll"](editor);
function getSelectedRange() {
return { from: editor.getCursor(true), to: editor.getCursor(false) };
}
function autoFormatSelection() {
var range = getSelectedRange();
editor.autoFormatRange(range.from, range.to);
}
function commentSelection(isComment) {
var range = getSelectedRange();
editor.commentRange(isComment, range.from, range.to);
}
</script>
If you put the formatting.js file in the addons folder of codemirror 4 and reference it, the functions will work.
Location: addon/format/formatting.js
include the script file in your html
Call the formatting code (example at http://codemirror.net/2/demo/formatting.html)

You can use any 3rd party formatting tools, like JS Beautifier (it supports CSS, HTML and JS)
Add custom button
Add onclick handler for it
Use editor.getValue() and editor.setValue(string) from API
jQuery(function($) {
var editor = CodeMirror.fromTextArea($('#code')[0], {
lineNumbers: true,
mode: 'text/javascript',
theme: 'oceanic-next'
});
$('#format').on('click', function() {
editorContent = editor.getValue();
editorContent = js_beautify(editorContent, {indent_with_tabs: true});
editor.setValue(editorContent);
editor.refresh();
});
});

I have got following jquery tags plugin.

best way is to count the number of "tag" classes already added, and then you can handle it differently, for example you can prevent showing the "add a tag" input once 5 tags inserted by defining maxTags and updating jQuery.fn.addTag and jQuery.fn.removeTag :

How about adding something like this:
if($('.tag').length>=5){
$('#tags_tag').attr('disabled','true');
}
I put a little more flair into my demo.
Probably the easiest solution is to change line 89 of jquery.tagsinput.js from:
var skipTag = $(tagslist).tagExist(value);
to:
var skipTag = $(tagslist).length > 5 || $(tagslist).tagExist(value);
