enable disable dropdown list with radio button control

[KIrk Anderson 6]

I have included a simple javascript function that i am hoping someone may tell me why this would notwork in Spotfire 7.11 (as i have tried) and could also tell me how to implement thissimple js function.

Ultimately i want to disable/enable3 different dropdown controls based on the corresponding selection of a radio control which has 3 value options to select from.

thanks very much in advance.

Show / Hide Spotfire Controls from Dropdown

html:

 

 

 

 

js:

$("#c970da0f1b5549a88d27f368f6770f2f").on('change',function(){

$("option:selected",this).text()=="Show"

$("#showHidecontainer").fadeIn():

$("#showHidecontainer").fadeOut()

})
