struggle with text in textdevice

[BartSr]

I'm struggling with a textdevice which I want to show information on two (2) lines.

command in dzVents

Code: Select all

dz.devices(1642).updateText('line 1'..'\n line 2')

this results in:

Code: Select all

line1 line2

but I expected

Code: Select all

line1
line2

what's wrong?

[HvdW]

Change it to:

Code: Select all

dz.devices(1642).updateText('line 1\n line 2')

or

Code: Select all

local textSensor = dz.devices(1642)
            if textSensor then
                local text = 'line1'..
                '\n\n line2'  
                textSensor.updateText(text)
             end

According Dummy wiki for text sensors: you get multiple lines when adding \r\n to the string

The problem is weird.
It apprears that the text-device itself had no problem but it occurs once the same textdevice is placed on floorplan.

Don't use floorplan (not yet..) but try maybe:

Code: Select all

dz.devices(1642).updateText('line 1<br>line 2')

@Ronka
thanks for suggestion.
your solution works fine for textdevice but if it's on a floorplan it shows up as:

feels like being a bug

Bug or perhaps intended to not have too much data on the floorplan.

[BartSr]

Walter, I expect 1st: bug. I will report abot it.

Looking at this part of code in the floorplan it looks like it should work with line breaks.
https://github.com/domoticz/domoticz/bl ... s.js#L1891

Code: Select all

        this.data = item.Data.replace(/([^>\r\n]?)(\r\n|\n\r|\r|\n)/g, '$1<br />$2');
        if (this.data.indexOf("<br />") != -1) {
            this.hasNewLine = true;

Perhaps look with source code option in a browser if you see the <br /> in html

I asked AI what this should do and it came up with the following description:
This JavaScript line uses a regular expression to replace newline characters in a string with HTML line break tags (<br />).
Here’s a breakdown of how it works:

Regular Expression: /([^>\r\n]?)(\r\n|\n\r|\r|\n)/g
- ([^>\r\n]?): This captures any character that is not > or a newline character, zero or one time.
- (\r\n|\n\r|\r|\n): This captures any of the newline sequences (\r\n, \n\r, \r, or \n).
The g flag at the end indicates a global search, meaning it will replace all occurrences in the string.

Replacement String: '$1<br />$2'
- $1: Refers to the first captured group (any character not > or a newline).
- <br />: Inserts an HTML line break.
- $2: Refers to the second captured group (the newline sequence).

In essence, this line of code ensures that every newline in the string is replaced with an HTML line break, preserving the newline characters themselves. This is useful for displaying text with line breaks in HTML.

Man.. this is quickly turning in to a rabbit hole..

In HTML (up to HTML 4): use <br>

In HTML 5: <br> is preferred, but <br/> and <br /> is also acceptable

In XHTML: <br /> is preferred. Can also use <br/> or <br></br>

Notes:

<br></br> is not valid in HTML 5, it will be thought of as two line breaks.
XHTML is case sensitive, HTML is not case sensitive.
For backward compatibility, some old browsers would parse XHTML as HTML and fail on <br/> but not <br />

So.. <br /> is the way?!?

sorry, no same result as on yr previous proposel....
