Adding a banner to chat messages

[phenomlab]

@DownPW let me know how you get on.

[DownPW]

Work now with empty chat room, Thank you
But they appear at the very bottom of the chat :

Just see that the banner is displayed even after a system event :

component="chat/system-message"

System events should be considered as a separate message for thebanner message to be displayed below.

@DownPW did the chat banner work in the way you expected here?

@DownPW I think this is what you want - let me know

in this case, the code has to be modified so it looks like the below

// Chat message banner
function chatBanner() {
    var roomName = $("h5[component='chat/header/title']").text().trim();
    var bannerContent;
    if (roomName === "Testing 3") {
        bannerContent = '<div id="chatbanner">This message will fire for chat rooms with the title of "Testing 3"</div>';
    } else {
        bannerContent = '<div id="chatbanner">This session is for <strong>private discussion only</strong> between the chosen participants. Please do <strong>not</strong> place support requests here and create a <a href="#" onclick="app.newTopic();">new topic</a> instead.</div>';
    }
    var chatMessagesContainer = $('[component="chat/system-message"]:last-of-type');
    var existingMessages = $('[component="chat/message"]');
 
    if (existingMessages.length === 0) {
        // If there are no messages, append the banner to the messages container
        chatMessagesContainer.first().after(bannerContent);
    } else {
        // If there are messages, add the banner after the last message
        existingMessages.last().after(bannerContent);
    }
}
 
$(window).on('action:chat.loaded', function(data) {
    $(document).ready(function() {
        chatBanner()
    });
});

This will place the banner after the last system message and before any of the messages themselves. If there are existing messages in the room, the banner will be placed at the footer of the last message so it is seen each time.

Thanks Mark, you are a champion

Test this code ASAP

[DownPW]

I have tested now this last code, It’s clearly better, Thnks you again.
Just one things mark @phenomlab, the banner don’t appear if there is empty (no message) :

[phenomlab]

@DownPW Does it appear if you reload the page?

[DownPW]

@phenomlab nope

[phenomlab]

@DownPW Very odd - I see this on your DEV server

[DownPW]

It’s because you have joined the public chat and so we have a system message. (Phenomlab as joined the room…)

If you are the creator of the room, no joined her and 0 message (user and system message), banner don’t appear but it’s not very serious

[phenomlab]

@DownPW Can you create another ? I should be able to get this to work…

[DownPW]

ok, I recreated the "“Support” lounge

[phenomlab]

@DownPW Can you create a new room? There are events in the old one which will trigger the message

[DownPW]

ok, no problem

[phenomlab]

@DownPW I can’t replicate this issue. Each time I access the room, it will add a system event which causes the JS to trigger

[DownPW]

hmm I think because you have not create the room like me but like I said, it’s not very serious

[phenomlab]

@DownPW Nope. I get the same if I create the room

[phenomlab]

Here’s a small modification to the chatBanner function that will place the message just above the composer/reply component meaning it is pinned at the bottom and always in view as a reminder. I’ve made this change to support the threadedChat I’m currently developing

// Chat message banner
function chatBanner() {
    var roomName = $("h5[component='chat/header/title']").text().trim();
    var bannerContent;
    if (roomName === "Testing 3") {
        bannerContent = '<div id="chatbanner">This message will fire for chat rooms with the title of "Testing 3"</div>';
    } else {
        bannerContent = '<div id="chatbanner">This session is for <strong>private discussion only</strong> between the chosen participants. Please do <strong>not</strong> place support requests here and create a <a href="#" onclick="app.newTopic();">new topic</a> instead.</div>';
    }
    var chatMessagesContainer = $('[component="chat/system-message"]:last-of-type');
    //var existingMessages = $('[component="chat/message"]');
    var existingMessages = $('[component="chat/composer"]');   
    if (existingMessages.length === 0) {
        // If there are no messages, append the banner to the messages container
        chatMessagesContainer.first().after(bannerContent);
    } else {
        // If there are messages, add the banner after the last message
       // existingMessages.last().after(bannerContent);
       existingMessages.before(bannerContent);
    }
}

There are only two changes here:

var existingMessages = $('[component="chat/message"]');

becomes

var existingMessages = $('[component="chat/composer"]');

and

existingMessages.last().after(bannerContent);

becomes

existingMessages.before(bannerContent);

hi @phenomlab

since v3.9, widget chat room is officialy available with nodebb-widget essential.

I use this code for now for different banenr message for different room

// ------------------------------------------
// Chat messages banner 
// ------------------------------------------
 
// Several banner for several chat
 
function chatBanner() {
    var roomName = $("h5[component='chat/header/title']").text().trim();
    var bannerContent;
    if (roomName === "General") {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i> Message 1. </div>';
    } else if (roomName === "Support") {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i>  Message 2.</div>';
    } else if (roomName === "Info") {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i>  Message 3</div>';
    } else if (roomName === "xxxxxxx") {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i>  Message 4.</div>';
    } else if (roomName === "xxxxxxxx") {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i>  Message 5.</div>';
    } else if (roomName === "xxxxxxxxx") {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i>  Message 6.</div>';
    } else {
        bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i> Ce canal est une discussion privée. </div>';
    }
    var chatMessagesContainer = $('[component="chat/system-message"]:last-of-type');
    //var existingMessages = $('[component="chat/message"]');
    var existingMessages = $('[component="chat/composer"]');
 
    if (existingMessages.length === 0) {
        // If there are no messages, append the banner to the messages container
        chatMessagesContainer.first().after(bannerContent);
    } else {
        // If there are messages, add the banner after the last message
        //existingMessages.last().after(bannerContent);
        existingMessages.before(bannerContent);
    }
}
 
$(window).on('action:chat.loaded', function(data) {
    $(document).ready(function() {
        chatBanner()
    });
});

On the new widget, only the last message appears :

} else {
      bannerContent = '<div id="chatbanner"><i class="fa fa-fw fa-circle-info link-primary" aria-hidden="true"></i> Ce canal est une discussion privée. </div>';
  }

When I Change room on the chat room widget, no change.

It’s possible to adapt the code for chatroom widget without bug if we don’t use the chatroom widget ?

many thanks
