justgage refresh with ajax

Question

I might just be being a bit dim here, or it might be my relative weakness with javascript, but I'm kinda stuck.

I have a justgage dial, showing number of people checked in an office, out of a total number.

I have a setInterval call just after the gauge is initiallised. But I want to update BOTH the number present, AND the total number, because both might potentially change. I can get the numbers via an ajax call to my own api - but because the ajax call is asynchronous, if I use

setInterval (g.refresh(myfunc()), 1000)

how do I get multiple returns out of myfunc.

Alternatively, if I do

   setInterval( myfunc(g), 1000)
   function myfunc(g){
       var foo=g;
       $.ajax(blah)
           .done(function(json){
                // no g here
           })

I have no reference to g on successful ajax call. (Though it is visible at var foo=g)

How do I get around this (multiple returns, or visible object)

Answer 1

Maybe there is a better solution but try to create the foo var as global and then you can use this in all the places you want.
