XF 2.0 Set a variable via js for use as template condition

[Idhae]

hello,
i would check a heigth of a div via js, then set this height to a variable to check this one in template condition.

Somebody an idea how i could realise this? Some Code examples how i could set the variable from js to <xf:set / <xf: page ?

JavaScript is executed on client side after the response has been passed off. Your server is long done executing template syntax and php by the time JavaScript even starts to run.

ok, then i have to figure out another way.

thanks

i found a way:

• content loaded standard css "visibility: hidden"
• JS check for heights
• JS make the DOM Element css "visibilty: visible" if height OK, otherwise remove DOM Element.
