Inline IF ELSE doesnt work?

[Neo Andersson 230]

@jgab Jan, i used to use inline IF ELSE abbreviations like

 

variable1 = variable2 == false and false or true

 

and it worked for me but thise line doesnt work. I want to get the useHTML quickapp variable, that is always a string value, and convert it to a bolean while assigning it to variable USEHTML

 

USEHTML = self:getVariable("useHTML") == "false" and false or true

 

Where is the trick?

Hi,

 

First is self:getVariable("useHTML") value "true"  /"false" or "0" / "1"

Use print(self:getVariable("useHTML")) to check what value is stored there ...

I know what value is storeed there. This is not the question..There is either "false" or "true" stored (in string type, as QA variables are stored always as string).

USEHTML = (self:getVariable("useHTML") == "false") and false or true

No, it doesn't work this way. Replacing "inline ifthenelse" with "and or" has pitfalls if you return boolean values.

In your case it won't return false if there is a "or true" the end. In this case the "or true" will return.

You can code around it by switching the test

Wow, thanks..the last one is pretty neat

@jgab Jan, these days its pretty hard to catch you online...I hope you are doing well...

May i ask one more question...I am struggling hardly with multiselect.. (i am not using the new view at all it is even worse) but in the old view, i just cant do some action

 

1. I cant select all the devices by code

 

2. and most importantly i cant delete the dropdown options..it just doesnt work... self:updateView("dd","options", {}), neither  self:updateView("dd","options", nil) nothing works..

 

3. How to unselect an item by code

 

Are these things even posssible
