Trigger .click() on a link on mobile view only - javascript

So I'm currently working on a WordPress website with a Table of Contents plugin. All the plugin do is just detect headings and add them to its contents.
What I am trying to achieve on my current website (https://staging.vladesplana.com/planning-center-vlad-test) is that when the Window is at <= 768px, it should simulate a "click" event on the [ Collapse ] anchor link so that the Contents will be hidden on mobile load and only be Expanded when on Desktop pixels (1280px, etc) load
function tocToggle2() {
if (window.innerWidth <= 768) {
document.getElementsByClassName('lwptoc_toggle_label').click();
}
}
window.onload = tocToggle2;
May I know your thoughts or the proper code for this? I mainly just build websites on Elementor and know only basic Javascript.
Tried a few things as well from my searches and on Stack to no avail.
I use Custom CSS & JS plugin to insert CSS and JS codes into my WordPress website so please, no JQueries
EDIT: Corrected some of the codes.

Oh I think I got it.
I just added [0] on this line:
document.getElementsByClassName('lwptoc_toggle_label')[0].click();
Source:
https://www.geeksforgeeks.org/click-method-not-working-and-console-returns-an-error-message-in-javascript/#:~:text=click%20is%20not%20a%20function,you%20have%20written%20a%20document.
Since it says there:
If you spelled it correctly then probably this error arises because you are not aware that document.getElementsByClassName returns an array of elements, not a single element. In order to avoid the error, you need to access a single element and then perform a click().
I checked in the console as well to check if the function is working as intended but it throws an error there.
final code:
function tocToggle2() {
if (window.innerWidth <= 768) {
document.getElementsByClassName('lwptoc_toggle_label')[0].click();
}
}

Instead of using getElementsByClassName, which will give you a list with every matching element, use querySelector, which will return the first one it finds.
The reason your code isn’t working is because you can’t trigger a click on a list of nodes.

Custom Javascript code in a specific page

I would need to add a javascript code within a specific page of my wordpress site.
I would like to find a solution via plugin, otherwise maybe I could modify the code I already use specifying the page, but I don't know how to do it
This is my code:
( function( $ ) {
$(document).ready( function() {
$('.title_subtitle_holder_inner > h1:nth-child(1) > span:nth-child(1)').text('EVENTI');
});
})( jQuery );
I would need that text to be edited on a specific page, in my case the page id would be 217
Thank you
Probably no harm in injecting that minimal code into all pages, just make it so that it selects elements only when on your specific target page.
WordPress creates a class page-id-XY on the body element automatically, so just prepend your selector accordingly, so that it will only select elements on that specific page:
$('body.page-id-217 .title_subtitle_holder_inner > h1:nth-child(1) > span:nth-child(1)')
You can try to use this:

Or any other method for custom scripts on specific page. From what I recall I think WordPress has this functionality built in.

jquery - check, if .class is present & and then automatically add .class to specific #id on one page

jquery - check, if .class is present on site or at specific #id and then add .class to specific #id
hey folks,
I know, there are many topics (30586451, 27947009, ...) regarding a similar issue, but i tried at least 15 code snippets in js and jQuery and none of them seem to work for me whereas other scripts just work fine on the same page.
I am currently coding a static site using Hugo server and no matter, what i try, i can't get a necessary .class to automatically get added to a certain #id. This should happen only if another .class is present on the current visible siteelements. The page is a one page which dynamically shows and hides content based on navigation without reloading but different anchors get pushed into the url (also tried listening to that but no avail). It is put together from .md, .toml and .html bits.
I can see the trigger class in the src code (tried in html tag and somewhere in body) and the script is as well (with older & recent jquery / before )
any ideas?
thank you!
<script type="text/javascript">
jQuery(document).ready(function() {
if($('classA').attr('id') == 'idB')
{
$('idC').addClass('classD');
}
});
</script>
You need . before class and # before ID in selectors.
You can create a single selector that searches for both class and ID: #idB.classA
jQuery(document).ready(function() {
if ($('#idB.classA').length > 0) {
$('#idC').addClass('classD');
}
});

jQuery .attr Not Working Properly, Miss-Retrieving Links

This is a page I'm currently working on as a project
$(function() {
$(".modal-launcher, #modal-background").click(function() {
$(".modal-content, #modal-background").toggleClass("active");
$(".vid-1i").attr("src", "link1");
$(".vid-2i").attr("src", "link2");
$(".vid-3i").attr("src", "link3");
$(".vid-4i").attr("src", "link4");
$(".vid-5i").attr("src", "link5");
$(".vid-6i").attr("src", "link6");
$(".vid-7i").attr("src", "link7");
$(".vid-8i").attr("src", "link8");
//$('html').toggleClass('active').css('top', -(document.documentElement.scrollTop) + 'px');//
});
});
above the actual links are replaced just to display a quick idea of the bad jQuery.
In it, I am attempting to create my own popup launcher for videos; however, I am having trouble using jQuery to replace the "" src of an iframe element to a YouTube link. I am unable to figure out why the jQuery is not working. I understand that the jQuery is, of course, working properly, and that it is me who has written the code incorrectly, but here I am asking if anyone is able to figure out what it is I've done wrong, or what can be changed to make it work.
For some reason, the last video in the jQuery list is always the one retrieved.
Understand that the images are missing from the page due to them being local files and not network locations. Clicking above the captions that read like "Match One" will have the "intended" result, regardless if the image is showing or not.
Coming back to this and understanding more of JavaScript and jQuery, my problem was simply misunderstanding the code. In order to do something like this, one function per link would be more suitable.
function video1()
{
$("#popup, #modal-background").toggleClass("active");
$("#popup").prop("src", "https://www.youtube.com/embed/7h1s15n74r3all1nk");
document.getElementById('scroll').style.cssText ='overflow:hidden';
}
complementary html would look like this:
<div onclick="video1()"></div>
The previous code would run each line, effectively setting the last link as the source of the element. The new code is button independent, ensuring only one link belongs to each button.

Is it possible to create element on the fly with jQuery Mobile?

I have an app built using jQuery (and using various jQuery-UI tools).
For some reason, i have to port it to smartphones/tablet computer, and decided to use jQuery Mobile for that (in order to minimize the number of changes).
In my vanilla app, I created some elements of the page on the fly, depending of user interactions.
For example a slider could be created like that (p is an object with a bunch of params):
function createSlider(p){
return $("<div/>",{
"id":p.id,
"class":p.divClass,
}).slider({
"orientation": p.align,
"min":p.constraint.min,
"max":p.constraint.max,
"step":p.step,
"value":p.curVal,
"animate":"normal"
/*and some event handling here, but it doesn't matter*/
});
}
And it will produce a nice looking slider. Now it looks like:
function createSlider(p){
return $("<range/>",{
"id":p.id,
"class":p.divClass,
"min":p.constraint.min,
"max":p.constraint.max,
"step":p.step,
"value":p.curVal,
});
}
But as it's created on the fly, all the stuff done by jQuery Mobile on the page load isn't done on it.
Is there a way to force that initialization without writing the slider in the html?
Thanks.
EDIT: I found in the doc that it could be achieved using container.trigger("create");
However this does not work yet.
EDIT2: Ok create was the solution.
According to the documentation (see edit in the question), using trigger("create") on the containing element works.
And to make that work, you also need to remember that range is an input type and not a tag...
Working solution:
function createSlider(){
return $("<input/>",{
"type":"range",
"id":"sl",
"min":0,
"max":15,
"step":1,
"value":1,
});
}
function appendSlider(){
$("#yourdiv").append(createSlider()).trigger("create");
}
As a sidenote, the documentation for jQuery mobile lacks a search option.
Try calling .page() on the container the content is being added to. Alternatively, adding .page() to the content you're returning may also work.

Javascript getElementById - reading works, altering doesn't

So, I have this pretty complex ajax thing going.
It loads new html (including div tags and all) to show up on the page.
I included a 'more' link to load additional data.
This more link links to my javascript function. The 'more' link is located in a div, which I gave a unique id. The next time the load function is called, I use document.getElementById(the id).style.display="none"; to "remove" this div from the look of the page.
I set error traps for this, the div with that id is found without problems, but javascript fails to change my style property.
I tested alert(document.getElementById(the id).innerHTML); and that worked without problems - hence the title of the question.
So, does anyone have any ideas/do I need to offer more information? The main problem is that it doesn't throw any errors anywhere, yet it fails to complete the task I asked...
Here's a bit of code to go with it -
try
{
var myidthing = "morelink" + ContentStart.toString(); //the id is correct
var div = document.getElementById(myidthing);
if (!div)
{
}
else
{
div.style.display="none"; //this doesn't work, but doesn't raise an error
alert(div.innerHTML); //this works without problem
}
}
catch(theerr)
{
alert(theerr);
}
------------------------->EDIT<-------------------------
I'm incredibly sorry if I upset any people.
I'm also angry at myself, for it was a stupid thing in my code. Basically, I had a variable that stored the contents of a parent div. Then I (succesfully) removed the div using the removeChild() method. Then my code pasted the contents of that vaiable (including the div I wanted gone) back into the parent div.
I switched around the order and it works fine now.
Again, excuse me for this.
Throwing out a few ideas of things to look for:
You said the div is generated by javascript. Is it possible the div you are targeting is not the one you think you are? It could be you are targeting another div, which is already hidden, or obstructed... or maybe the innerHTML you are displaying goes with a different element than the one you intend to target. Put an alert or script breakpoint in the if(!div) case, also, and see if it's going down that path.
If the above code is only a stripped-down version of your actual code, check your actual code for typos (for example: style.display = "none;";)
Using the FireBug plugin for FireFox, inspect the target element after the operation completes, and make sure that the display: none appears in the style information. If not, use FireBug's debugger to walk through your javascript, and see if you can figure out why.
Use FireBug to break on all script errors, in case there is another error causing this behavior.
Try empty quotes instead of 'none' and see if that works?:
document.getElementById('element_id').style.display="";
Failing that, don't change the style, just add a class which hides the element.
