Javascript- Client API

Hi All,

I am trying to build a JS code which has to retrieve the attribute present on form and print the values to a multi line of text in comma separated form. The attribute datatype must be of Boolean type.

I started from here

function getboo(executionContext){
debugger;
var formContext = executionContext.getFormContext();
var coll = formContext.getAttribute(boolean);
}

Thanks in advance
