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.

Hi there I'm pretty new to using functions and onclick actions to call javascript so I could do with some help. Basically, I've installed a plugin on WordPress which adds a button to the page in the form of a widget and once clicked it starts a script. However, I don't like their button so I'm trying to code my own but I want it to start the script like there's.
Here's the script code:
/*
* Timely BookButton plugin
* Example usage:
* var button = new timelyButton('doedayspa');
*
* Booking process can be kicked off manually by calling the start method on the button instance e.g.
* button.start();
*

So how can I run this javascript when I click the button?
Any help would be greatly appreciated!
You could create a script tag automatically if the button has been clicked.
document.getElementById('myButton').addEventListener('click', () => {
const script = document.createElement("script");
script.src = 'my-other-file.js';
document.head.appendChild(script);
})
<button id="myButton">Load JS File</button>
I have a Multi-Level Accordion Menu - from a FAQ - with 2 levels.
Each level have a 13 Questions / Answers.
My problem:
One of the Questions/Answers have a lot of information. (almost 10 pages).
The other Questions/Answers have 3, 4 lines of information each.
The Question with many information is number 7.
Then When I click on question 7 - the answer 7 is open. with many information, and the user must scroll down the page to read all.
Until here, OK. no problem.
but at end - If I click on Question 8 - to read the answer, the menu closes question 7 (ok) - open question 8 (ok) - but the page still in the footer - the page dont scrolls up with the faq..
With all other questions - because they are small - I can see in same screen almost all 13 questions + the answer opened.
With question 7 - no. the page scrolls down and don't scrolls up - when we close the question 7.
There is a way to solve this? I think I need to create an anchor for each question..

Before I get into details, please take a look at the live example where this problem occurs - http://jsfiddle.net/66HFU/ (Script code at the bottom of this post)
Now if you would click on any image at last row, it would display these. However if you would click on upper row images, below row images are shown.
Further investigation shows that for somewhat reason the letter called function selector elements only get binded with event listener while the firstly called functions selector elements do not.
So, I would like to know is there are any ways to make the function call independent so the latter function call does not override first one (if that would fix the problem, of-course)?
The place where the event function gets bind on the element can be found in function f_AddEvents first lines.
And the the main function calls that are used to initialize Light Box is at the bottom of the code like this:
LightBox.init({
selector: "[data-simplbox='demo1']",
boxId: "simplbox"
});
LightBox.init({
selector: "[data-simplbox='demo2']",
boxId: "simplbox",
imageLoadStart: activityIndicatorOn,
imageLoadEnd: activityIndicatorOff
});

Your code is almost working. What you handled badly is the fact that you can perform several init. On each init, you overwrite some items, especially with this line :
base.m_Elements = document.querySelectorAll(base.m_Options.selector);
So base.m_Elements will only have the elements of the last init.
( Based on the name 'init' i wonder if the real use case wouldn't be to allow just one call of init... )
Quick-fix is to do one single init with :
LightBox.init({
selector: "[data-simplbox='demo1'],[data-simplbox='demo2']",
boxId: "simplbox"
});
(erase the two calls to init)
And here it works.
http://jsfiddle.net/gamealchemist/66HFU/1/
So i guess either you want to support several init, or (easier to maintain in fact), throw exception on multiple init and expect the lib user to write the right selector in the single init call.
Edit : Super quick fix for your issue : rather than having LightBox as a singleton, have it as a Class :
function LightBox( initArguments ) {
// something like what was done in init
}
LightBox.prototype = {
f_RemoveImage : function() {
} ,
f_OpenImage : function( ..., ... ) {
} ,
...
}
then you can call with no issue :
var demo1LB = new LightBox({ selector: "[data-simplbox='demo1']",
boxId: "simplbox" });
var demo2LB = new LightBox({ selector: "[data-simplbox='demo2']",
boxId: "simplbox" });
I'm facing weird behaviour of Jit Infovis i'm using. I have two different html files that include a load json function from a Javascript file. The function is using infovis library to display a hypertree map from a json file. Both two html files load the same json file.
One html file has been succeeded rendering the map properly. But another one has not. It renders the map almost properly, but after i debugged it, i got it not iterating over the root node. Then, the root node becames inactive without label and clickability.
This is the js function i'm using.

//and that as of today iPhone/iPad current text support is lame

What's probably causing this?
Please check whether there is conflict id. Basically infovis render each nodes by the id.
And if there is an DOM element that has the same id with one DOM element of a node. It would conflict and won't render
you can check it by duming dom element iterating over the nodes.
I am trying to work with a simple WYSIWYG editor. JSLint is saying it has "Bad escaping of EOL". Since I am new to javascript I am having a hard time figuring out what it means, since I am working with code found online. Can anyone tell me please what I should be doing instead of ending the line with a slash?
Here is the code in question: http://jsfiddle.net/spadez/KSA5e/9/

EDIT: For bonus marks there are also two other errors which I haven't been able to squish -
Missing radix parameter
Height is better written in dot notation
JS didn't support end-of-line escaping with \ until ES5 - you can use multiple strings with a + operator instead, i.e.
"string 1" +
"string 2" +
"string 3"
Re: your other questions:
Use parseInt(n, 10) to force base (aka radix) 10, i.e. decimal
Use iframe.style.height instead of iframe.style['height']
You have two options:
1) activate multistr: true as suggested by #csharpfolk. (You can do it at file level by adding /*jshint multistr: true */ or add it in your linter config file (.jshintrc, .eslintrc, etc.)).
2) Replace your multistring as suggested by #Altinak or use an array and join:
["string 1",
"string 2",
"string 3",
].join('')
