Block Domain

DownPW

I search a javascript code for nodebb to block and replace with a specific/customize message domain an URL Wirth a blacklist on topic, quick reply and composer like plugin-beep do it.

I’m working on it but I don’t have anything that works, hence the request for help from your expertise.

here an exemple who doesn’t work

// Add this script in a custom JavaScript file or inline in your HTML

document.addEventListener('DOMContentLoaded', function () {
  // List of blocked domains or URLs
  var blockedDomains = [
    'example.com',
    'blockeddomain.com',
    // Add more domains as needed
  ];

  // Custom message to be displayed for blocked content
  var blockedMessage = 'This content is blocked.';

  // Function to check if a URL contains a blocked domain
  function isBlocked(url) {
    for (var i = 0; i < blockedDomains.length; i++) {
      if (url.includes(blockedDomains[i])) {
        return true;
      }
    }
    return false;
  }

  // Function to replace blocked content
  function replaceBlockedContent(content) {
    // Check if the content contains a blocked domain
    if (isBlocked(content)) {
      // Replace the content with the blocked message
      return blockedMessage;
    }
    return content;
  }

  // Get all the elements containing topic content (adjust the selector as needed)
  var topicContentElements = document.querySelectorAll('.topic-content');

  // Iterate through each element and replace blocked content
  topicContentElements.forEach(function (element) {
    element.innerHTML = replaceBlockedContent(element.innerHTML);
  });
});

Thanks

I have a great code here. I managed to modify the HTTP URL link as well as the link text (description) by modifying them both with a warning message and the URL of my choice for each domain. I am currently redirecting to my checkout page.

The code also differentiates with text before and after the link and does not take it into account.

It works :

In the topics
In the carousel
In the previews of the last post in the recent page, unread etc…
In Chat

There are certainly things to improve but I’ll share the code with you here.

@DownPW What should the desired effect be from the composer - for example, prevent submission etc? If you can provide a bit more info in relation to what should happen, this would be beneficial.

DownPW

I would prefer the same behavior as the nodebb-plugin-beep plugin :

The URL is replaced in the quick reply component, the composer and in topics but does not prevent the submission of the message or post, just replace URL

I changed my approach and I have code that works but only on topics using [component="post"] but after posting the message, URL is not replaced I must refresh the page.

$(document).ready(function () {
  $(window).on('action:ajaxify.end', function () {
    // Target the post content within the post component
    $('[component="post"]').each(function () {
      var $postContent = $(this).find('.content');

      // Replace the old domain URLs with the new domain URL
      $postContent.html(function (index, oldHtml) {
        // Match the old domain URLs
        oldHtml = oldHtml.replace(/https?:\/\/(www\.)?francesoir\.fr[^\s]*/g, 'https://new-domain.com');
        oldHtml = oldHtml.replace(/https?:\/\/(www\.)?francais\.rt.com[^\s]*/g, 'https://new-domain.com');
        return oldHtml;
      });
    });
  });
});

DownPW

working code only on topics :

$(document).ready(function () {
  // Function to replace URLs in a given HTML content
  function replaceUrls(html) {
    // Replace the old domain URLs with the new domain URL
    html = html.replace(/https?:\/\/(www\.)?francesoir\.fr[^\s]*/g, 'https://new-domain.com');
    html = html.replace(/https?:\/\/(www\.)?francais\.rt.com[^\s]*/g, 'https://new-domain.com');
    // Add more lines for additional domains if needed
    return html;
  }

  // Replace URLs when a new post is added
  $(window).on('action:posts.loaded', function () {
    $('[component="post"]').each(function () {
      var $postContent = $(this).find('.content');
      // Replace URLs in the post content
      $postContent.html(replaceUrls($postContent.html()));
    });
  });

  // Replace URLs when a post is edited
  $(window).on('action:topic.loaded', function () {
    $('[component="post"]').each(function () {
      var $postContent = $(this).find('.content');
      // Replace URLs in the post content
      $postContent.html(replaceUrls($postContent.html()));
    });
  });
});

It’s already not bad, just adapt it for the quick reply and composer

phenomlab

@DownPW what you have is already what I would have suggested - particularly the hooks - as you indicate, it just needs expansion to cover other aspects.

However, it’s worth noting that none of the code you have will prevent someone from viewing the source, and seeing the true URLs as you are not modifying any of the database entries.

DownPW

yes you are right but it is not very serious. Most of my users won’t look at the source code but if you have better why not.

If you have any ideas for adapting it to quick reply and composing. I’m interested. I’m taking a little break for now

Let me have a look at this in more detail in DEV.

DownPW

In previous code, i want to add html link to rules page like this :

html = html.replace(/https?:\/\/(www\.)?francesoir\.fr[^\s]*/g, '<a href="https://XXXXX.XXXXX.XXX/rules">Test</a>');

But i have this on result :

an idea ?

phenomlab

@DownPW Yes, direct HTML rendering is disabled (as is JS) in the composer so it will be stripped. For this to work, you’d need to enable HTML support in the composer which isn’t recommended for security reasons.

DownPW

too bad I would have liked to be redirected to the necessary page

ChatGPT doesn’t help on this

@DownPW that code looks great. I seem to have trained you well!

I’ll investigate the single line of code issue. I think that’s probably because of a modified version of highlight. js I use.

DownPW

@phenomlab

My code work great but a little more
My code conflicts with your OGPROXY code.

Do you have an idea so that the two can live together?

phenomlab

@DownPW Potentially, yes, but what is the conflict exactly?

DownPW

I don’t know, I just see that OG proxy does not format the links when my code to block domains is active.

If I disable it, OG proxy works fine.

I would have to make sure that OG proxy does not activate when a blacklist link is detected or that it works one after the other

Actually I don’t really know at the moment.

EDIT:

Maybe add an ignore list to OG PROXY

phenomlab

@DownPW said in Block Domain:

I don’t know, I just see that OG proxy does not format the links when my code to block domains is active.

This just means that the callback / hook isn’t monitored by OGProxy and can probably be quite easily rectified.

@DownPW said in Block Domain:

There is one already in function.js - see below

https://github.com/phenomlab/ogproxy/blob/03d5ff125611361700d785bd82a6ab16fcd68bfc/function.js#L9

DownPW

In any case, it doesn’t change anything in fact I think to add exclusions in OG Proxy, because links which are not to be ignored are not formatted by OG proxy

@phenomlab said in Block Domain:

I’ll look and try to figure it out but can you help me with this ?
