Add a class attribute to certain links

I have pages on my site that go through a translation proxy. I need the displayed text in certain links to not be translated. I can add class="notranslate" to the link and the translator will skip over it no problem. However, I have hundreds of pages created before I implemented the translator and I'll have hundreds more as I keep going along—manually adding the class is not really an option.
The links I'm specifically concerned with are ones whose display text are literal URLs or email addresses. The translator doesn't touch the href attributes so the links still work as expected, but the displayed string gets mangled. For instance, in Vietnamese, "organization#domain.com" is displayed as "tổ chức#domain.com," and a link whose display text should be "domain.com/committees" is translated to "domain.com/commitaries."
So I'm looking for a solution that finds a elements whose display text contains "#" or "/" and adds class="notranslate". I don't think I need too robust a solution as I otherwise don't use the "#" or "/" in link display text often, if ever, except in these situations. I would guess this could be done with Javascript, but I'm a JS beginner at best. An option that filters content on the backend through Wordpress could also be a nice solution.

This is simple using jquery, ideally this will need to load before your translations plugin.
Note: If you have jquery already loaded as most wordpress themes already do, then you can remove the first line from this code, which includes the jquery library.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script type="text/javascript">
$( document ).ready(function() {
$("a").each(function() {
let text = $(this).text();
if(text.includes("#")) {
$(this).addClass('notranslate');
}
if(text.includes("/")) {
$(this).addClass('notranslate');
}
})
});
</script>

How to remove special characters and codes (using jquery) from sharepoint rendered html?

I am Working on a branding of share-point application. In some cases, rendered html contains codes like '​'. In my slider, these are generated 8 times and in modal and content pages, their count is different. These codes are generating undesired white space. How can I remove these using jQuery? I tried to play with this like
$(".wrapper").filter(function(){
return $.trim(this.innerHTML) === "​";
}).remove();
But its not working.

Check below code which is a bit DOM-intensive but it does work.
$('#s4-bodyContainer').html($('#s4-bodyContainer').html().replace(/\u200B/g,''));
Let me know if it doesn't work.

How to disable hyperlinks within a PDF rendered by PDF.js

I'm looking into PDF.js for use in a web app. So far, it's meeting all of our business requirements. However, management has requested that we have the ability to disable hyperlinks within the PDF. We don't necessarily have to get rid of the blue text and underline, but if the user clicks on the hyperlink, it shouldn't go anywhere.
I've looked carefully through what API there is and couldn't find anything for it. I also looked through the source code, but nothing jumped out at me as something I could comment out in order to disable hyperlinks. Is there any way to disable hyperlinks contained within a PDF?

After a great deal of experimentation, I found out how to do this by modifying the source. There is a block of code that begins with the following:
document.addEventListener('pagerendered', function (e) {
At the end of the function before the close bracket, add the following code:
var allowInternalLinks = true;
var page = document.getElementById('pageContainer' + pageNumber);
var hyperlinks = page.getElementsByTagName('a');
for (var i=0; i<hyperlinks.length; i++){
if (!allowInternalLinks || hyperlinks[i].className != 'internalLink'){
hyperlinks[i].onclick = function(e) {
e.preventDefault();
}
}
};
What this does is take the rendered page, iterate through all of the hyperlinks on that page, and disable them. I have also added a boolean variable that allows you to optionally allow or disallow internal links (i.e. links that take the user to another location within the document).

How can I make a "reverse preventDefault" in jQuery?

In Private Logistics: Privacy-Sensitive Calendar, Todo, and Personal Information Management, data that is entered can be edited with a click, and there is support for either entering a link as <a href="... or entering a URL, which will be linkified.
This works great but it presents a problem when someone clicks on a link. The desired behavior is for the link to open and not to put the snippet of text into edit mode, which is the reverse of the usual pattern implemented by event.preventDefault()' or '...return false;}. (Clicks outside the link on the element should put the containing element in edit mode, same as a container that doesn't happen to have a link.)
How can I reverse the more common pattern using jQuery? My best guess now is to attempt introspection on the event target and see if it is an anchor. But that's just a best guess; I have seen plenty of examples of the pattern that would cancel the link loading another page but performing the added Ajax functionality of putting the container into edit mode; I'm not sure I've seen the reverse of that pattern which would follow the link and not put the container into edit mode.
I also see a way to dodge the matter by having links load in the same page, but that's the sort of solution I'd prefer to only adopt if there are intractable issues with implementation or the like.

Generally, you don't want to clean up your broad strokes, instead, don't make such broad strokes. Use an if statement prior to running e.preventDefault().
Something like:
var preventedLinks = $('a.preventthislink');
$('a').click(function(e){
if ($(this).index(preventedLinks) != -1) {
e.preventDefault();
}
});

you could alternatively just change the class of whatever you are preventing default on:
$(document).ready(function(){
$('.blue').removeClass('blue').addClass('green');
});

Assign links and classes in JavaScript

I have a site that is in English and Spanish, and in each page of the site there is a link that leads to the Spanish version of that specific page, so if the user were on the "home.php" page, it would look like this:
<div id="language">
<ul class="language">
<li class="english"></li>
<li class="divider"></li>
<li class="spanish"></li>
</ul>
</div>
What I would like to do is leave the href and the class in the <a> tags in the HTML blank and assign a class and an href URL to the <a> depending on the page the user is on, that way I could, for example, just add that language div to an external file, and use an <include> to attach it to each page. To accomplish this I'm using the following code:
$('ul.menubar a').each(function(){
if(location.href.match('home.php')){
$('ul.language li.english a').addClass('active');
$('ul.language li.english a').append(function() {
$(this).attr('onclick', 'return false;');
});
$('ul.language li.spanish a').addClass('notactive');
$('ul.language a[href!="home.php"]').append(function() {
$(this).attr('href', 'inicio.php');
});
}
}
The problem is that the English version of the site has 4 links in the navigation bar (home.php, services.php, aboutus.php, contact.php), and the Spanish version likewise (with the corresponding translation of the URL names). I think that having to repeat that code 8 times (1 for each link, 4 links in each language) would be excessive and would actually add more code than simply adding the class and href url in the HTML. The point of using JS would be to simplify things.
So I basically would like to know if anyone can think of a better way to do this, that wouldn't require that much code. I'm trying to avoid having to, in the event that I'd need to change something, have to edit each different page. Also, I would like to know if this is the best way to achieve want I want to do using JavaScript.

HTML is best suited for managing content. CSS is best suited for presenting that content, and JavaScript is best suited for determining how that content behaves. Instead of trying to inject links and control the HTML from JavaScript; instead, leave the content where it belongs, inside the HTML, and use JavaScript to define one or two event-handlers to take action based on the class values on the hyperlinks themselves.
You already have a class on your English hyperlinks, and a separate class on your Spanish hyperlinks, so you can use this to your advantage.
Writing the Click Handlers:
Since toggling your "Language switch" most likely causes a boolean value to be set, you can use two click handlers to target all of your English links and all of your Spanish links, and then control the behavior based on the value of that switch at the time the links are clicked.
// handler for all English links
$('li.english a').click(function(event) {
event.preventDefault();
if(/* Switch is english */) {
window.location = $(this).attr("href");
}
});
// handler for all Spanish links
$('li.spanish a').click(function() {
event.preventDefault();
if(/* Switch is SPANISH */) {
window.location = $(this).attr("href");
}
});
Note that when a link is clicked, we first check the switch. Depending on it's value, we either redirect to that hyperlink, or simply prevent the default behavior -- going to a new page -- from completing.
Handling the Presentation:
Now, your other problem is going to be that, assuming your Spanish site and your English site are one in the same, you'll now see 8 hyperlinks in total. Again, this is where your switch can come in handy.
// single handedly hide or display the relevant content, based on the switch
function switchToEnglish() {
$('.english').show();
$('.spanish').hide();
}
function switchToSpanish() {
$('.spanish').show();
$('.english').hide();
}
Now, I don't know what else is contained in your switch function, but the general idea here is that we don't need to modify the content. We just need to show and hide the content. You'd need to integrate this concept into your existing switch function, if you don't already have something like this in place.
There are several advantages in this approach:
Your Web designers will still see href's in the HTML and can read and understand the HTML without needing your help or needing to go and look at JavaScript code. Not only will they see familiar patterns that they're used to seeing, but you'll likely have a better working relationship with them.
Search engines spidering your site will be able to read the links and follow them.
Browsers without JavaScript will be able to process the links. Some people seem to care about this. I don't. But it's worth mentioning anyway.
In summary, you're right about it being easier to manage in HTML. By using this technique, you can eliminate the repetition in the code that you're rightfully concerned about, and also move the content back to the HTML, as your gut is telling you is the correct thing to do. Not only will your code be more readable, but you'll get better SEO results as well.
