Lovelace: Button card

[jchh ((not John))]

I’m not sure how to return anything in javascript (at least in button card, anyway) without it being in quotes based on all the examples provided in the repo.

Either way, I read that return false means ‘do not return anything’.

Definitely not. Do you have a source for that? Maybe you’re confusing the truthy and falsy values in YAML with this.

Regarding you original problem: Did you try changing'false' to false and 'true' to true?

@jchh

show_name: "[[[ if (Number(window.innerWidth) <= 1179) return 'false'; else return 'true'; ]]]"

Just this should do:

"[[[ return Number(window.innerWidth) > 1179); ]]]"

EDIT: show_name and show_state doesn’t support templating (see the docs).

Hi Pieter,

thanks for your reply - appreciated.

No, not confusing with YAML - I definitely read it whilst researching Javascript on stackoverflow or w3schools, but cannot find it now - maybe I misinterpreted the text. Thanks for correcting me.

"[[[ return Number(window.innerWidth) > 1179); ]]]"

thanks!

Well, that’s embarrassing, but I can see how I missed it. It doesn’t actually state that it doesn’t support templating, but all the options that do support tempting, explicitly state it. Thanks for pointing that out!
