How can I set iframe to automatically scroll to bottom? 1

[casabella]

I am working on a chat room. I am using an iframe to display messages. So far, it all looks good. The problem I am having is that at the current time, text is shown top to bottom where the last message shows on top and older messages scroll down.

I would like to reverse the scrolling or at least have the frame set so that it shows the bottom most content.

Aside from jumping to bottom of frame, I hope to find a solution that does not make the frame flash too much or make it too distracting.

Can this be done?

Regards,

Jose

Hi

A brutal way :

setInterval('frames[0].scrollTo(0,9999999)',1000)

Of course, not everybody will be happy if you force the scrolling.

feherke,

This is nice but where would I put it?

Thanks,

Hi

Oops, I forgot that part. Into the parent document which contains the [tt]iframe[/tt]. Of course, it requires the chat's [tt]iframe[/tt] to be the first [tt]iframe[/tt] on the page. But that requirement is easy to change. That code is just to give an idea. For better approach we will have to know more about that chat.

That did it!

I now have to deal with the PHP side of things so that I can retrieve last 50 or so records from MySQL table.

Thanks!

Hi

Oops. That is jpadie's script plus an [tt]iframe[/tt].

Then you could add the code to scroll to the displayUpdatedChats() function. Personally would add a checkbox to enable/disable the auto-scrolling feature.

Yes it is!

Good idea about the check box.

Hi

In thread434-1406514 you talked about changing the [tt]iframe[/tt] to [tt]div[/tt]. Please note that [tt]scrollTo()[/tt] and [tt]scrollBy()[/tt] are methods of the [tt]Window[/tt] object.
