Scroll Down - Chat
Question
JavaScript

Reactive

Hi buddies,


I hope you're doing well.


I'm developing a chat.

So, when the user writes a new message I want to scroll down automatically to the last message.



I used this script - $actions.ScrollToElement($parameters.WidgetId);  - but this script does scroll to the first message. (Client action - AdjustScroll)


Can you help me please?


Thank you,

FC

Hello @Fábio Miguel Ferreira Coelho,

The the awser from @Harika Ramadalai is almost right. 

Just need to change the JS to this:

var objDiv = document.getElementById($parameters.elementId);

objDiv.scrollTo(0,objDiv.scrollHeight);

Also instead of refer to the container by a class is better by an ID. After and this JS, you need to add an input parameter and also link that input to the ID of the container. See this images:

I try to add the OML, but I don't know why, now it have 7Mb and OS have a limitation of 4Mb. You can download from here:

Hi @Fábio Miguel Ferreira Coelho ,

You need to change the order of this events:

On the "SendMessage_OnClick" action.

Hope it helps,

Hi Nuno,


Thank you for your fast answer.


I did what you told me.

Now when I write a new message the Scroll Down works, but it goes to the penultimate message instead of goes to the last message.

Do you know why?


Thank you so much for your help!!


Kind regards,

FC

Hi Fábio Miguel Ferreira Coelho ,

Use the below JS to scroll to bottom of the list. .wrapper is class name. 

//CSS styles Height of container
.wrapper {
    height: 500px;
    overflow-y: scroll;
}
// JS to scroll to the bottom of the list
var objDiv = document.querySelector('.wrapper');
objDiv.scrollTop = objDiv.scrollHeight;

Hope this helps you.

Regards,

Harika
