Facing the same issue. Autoscroll doesnt work and everytime I have to scroll down manually to see the latest logs

@Bagunda @rakgenius which browser do you use?

[andrelung]

I am encountering the same issue with the latest chrome (76.0.3809.100). I might also add, that I am using frontail with openhabian

[ravening]

@mthenw Im using chrome browser Version 76.0.3809.100 (Official Build) (64-bit)

[Bagunda]

@Bagunda @rakgenius which browser do you use?
Chrome. It doesn't work about 1.5 years

[mthenw]

Can you paste me the exact command that you are running (or openhabian is running)?

[mthenw]

@Bagunda I cannot see that on your video but what happens when the window is scrolled to the bottom and you refresh the page? Does it go back to top?

[mthenw]

@Bagunda @andrelung @rakgenius can I ask you to validate the fix from #180?

[andrelung]

Openhabian is using the npm-based installation.
Line 30 you can see how it is installed: https://github.com/openhab/openhabian/blob/master/functions/nodejs-apps.bash
And here is the exact command (/service):
https://github.com/openhab/openhabian/blob/master/includes/frontail.service

I'll try uninstalling the npm version and installing your fix later today.

[Bagunda]

Can you paste me the exact command that you are running (or openhabian is running)?

frontail -d -n 100 --ui-highlight --ui-highlight-preset /usr/lib/node_modules/frontail/preset/default.json /var/log/openhab2/openhab.log /var/log/openhab2/events.log
or
frontail -d -n 1000 --ui-highlight --ui-highlight-preset /usr/lib/node_modules/frontail/preset/default.json /var/log/openhab2/openhab.log /var/log/openhab2/events.log

Today I try fix #180. At the end of the video https://www.youtube.com/watch?v=2Y6H5Qb7IGs
Autoscroll doesn't work.

I merged the PR and release new version (4.7.0) as it fixes @andrelung issue.

@Bagunda could you scroll your window to the bottom and run the following command in the dev tools?

console.log(window.innerHeight, window.scrollY, document.body.offsetHeight)

[Bagunda]

console.log(window.innerHeight, window.scrollY, document.body.offsetHeight)

[mthenw]

OK, looks like I know the culprit. Basically, your view is zoomed in. That's why the measurements are different than usual. Let me try to fix it.

[Bagunda]

Basically, your view is zoomed in.

In the settings of windows 10, I zoomed thescale.
Are you talking about this?

[mthenw]

@Bagunda yeah, that's probably it.

[riotm0de]

Openhabian 2.4 (stable)
Frontail 4.8.0
Raspb. 3 B
Chrome and Edge

no Auto-Scroll for me :(
Using "Simple-Autoscroll" Extension for Chrome in the meanwhile.

[radokristof]

Same problem on a zoomed scale. On normal scale it works as it should...

This is browser issue . works good in firefox or edge browser

[Wikibear]

This is not a browser issue. If you check scrollY you get a float. This float is to small and you be stay all the time under body height value.
What i recommand a math round in line 305 at app.js:

from

var wasScrolledBottom = window.innerHeight + window.scrollY >= document.body.offsetHeight;

to this:

var wasScrolledBottom = window.innerHeight + Math.round(window.scrollY) >= document.body.offsetHeight;

Maybe a button for auto scroll is a bit better.

I have this issue in all modern Browser like Edge, Chrom, Opera and Firefox.

NPM is version 4.9.1 with this bug.

No auto-scroll on Firefox (v94.0) on Linux...

Only change in Firefox is making fonts bigger - would that affect auto-scroll?
