javascript - How to access the value parameter of a new object created using JustGage? -

i didn't go digging, because don't think matters methods , forth justgage has, have new object g.

var g = new justgage({     id: "gauge",      value: 34,      min: 0,     max: 100, }); 

my question how retrieve value parameter later in script.

i thought var value = g.value work, doesn't.

here bit of justgage.js file:

 justgage = function(config) {    if (!config.id) {alert("missing id parameter gauge!"); return false;}   if (!document.getelementbyid(config.id)) {alert("no element id: \""+config.id+"\" found!"); return false;}    var obj = this;    // configurable parameters   obj.config =   {     // id : string     // container element id     id : config.id,      // title : string     // gauge title     title : (config.title) ? config.title : "",      // titlefontcolor : string     // color of gauge title     titlefontcolor : (config.titlefontcolor) ? config.titlefontcolor : "#999999",      // value : int     // value gauge showing     value : (config.value) ? config.value : 0, 

try g.config.value - looking @ justgage source code think it'll there.
