setting label visible = False with javascript

[Andre Hoefs]

Hi,

a label is filled as a result from my rest-service

i'd like to set the visible-property of a label to false if the label text is"undefinded".
I tried the following:

if ($('#zitat').text=="undefined") {$('#zitat').attr('visible',false);}

But it doesn't work....

Hello Andre,

Could you please clarify, for what event of what component do you add your js code? Maybe this link could be useful for you http://devcenter.appery.io/documentat...
