<script type='text/javascript'>//<![CDATA[ 
$(document).ready(function(){

              options:{
                zoom: 13
              }

            directionsrenderer:{
              //container: $(document.createElement("div")).addClass("googlemap").insertAfter($("#test")),
              options:{ directions:results }
            }
          });
        }
      }
    });


});//]]>  

</script>

So this the code, using gmap3 (gmap3.net)
So, problem is, it is showing the quickest way in minute.
If i want to go from A to B, may be it have 3 different route where 50 minutes 30 miles, 55 minutes 17 miles, 57 minutes 19 miles and it will first select 50 minutes/30miles route. But i need the route with minimum miles (55min/17miles).
is there any way i can do that?

Answer 1

results will contain an array with the 3 routes .

Find the desired route within this array(should be the 2nd in this case) and pass the index of the route via the routeIndex-property options(default is 0):

options:{ directions:results, routeIndex: 1 }
