On versions 0.42 and 0.43
If I have a page say No 2 title A then
a) page 2.t31.txt=t0.txt does not compile (Error: Invalid Page ID:page 2.t31.txt=t0.txt( Double click to jump to code)
b) page2.t31.txt=t0.txt does not compile though it used to on an older program
c) A.t31.txt=t0.txt works
If I have a page say 2 title A B then
d) A B .t31.txt=t0.txt does not compile
If I have a page say 2 title A_B then
e) A_B .t31.txt=t0.txt does compile
I would have thought that a) or e) are the correct formats and thus a) should compile? by the way there is no mention in the manual that page names should not have spaces
Page names shouldn't have spaces. Variable names shouldn't have spaces.
This concept is a carry over of programming.
When parsing occurs (in any parser) the space in the name will be interpreted as a delimiter.
The compile process checks and reports errors - never thought it needed to be mentioned explicitly.
(case a) not expected to work page 2 has a space
(case b) page0.t1.txt=t0.txt compiles and works in version v0.43
(case c) should and does work
(case d) shouldn't work as there are multiple spaces
(case e) shouldn't work as there is a space. Fails on version v0.43
Patrick... Taking out the spaces did not work.. Please see attached
to access variables on different pages, they also must be declared as global ...
and where is your page2?
and page names with a space ... read above from Patrick
1) yes, declared as variables
2) See RHS of screen shot Page 2 is named STA_MOD_SetUP
3) No spaces
I can make this code work if I use STA_MOD_SetUP instead of page2
I understood that the page reference was the nextion assigned page number, not its description
Is this incorrect? or is the manual ambiguous
wrong understanding ....
global variables are always referenzed by their pagename
and not by the page ID
a reason more to avoid spaces ...
it is also nowhere mentioned, that the id is used for variable referenzing ...
The preset examples show referencing to A and B, previous examples I have seen showed page1, page 2..
The 'refresh' function uses either the title or the page ID.
It seems to me using the page ID is much more sensible than the title which can be many characters long. This would have the advantage if you changed the title you don't have to go back through your code changing every reference
page2 is an example of a pagename. 2 is an example of a pageid
ref uses either the object name or the component id
only because page components always have component id of 0
does ref 0 cause a refresh of the current page.
In your picture, you have no pages name page2 - so it fails.
when you create a new page, the default set pagename is
but that's the pagename, not the pageid ...
