I'm using Google Maps API to do this
function getDist() {
var service = new google.maps.DistanceMatrixService();
service.getDistanceMatrix(
  {
    origins: [origin1, origin2],
    destinations: [destinationA, destinationB],
    travelMode: google.maps.TravelMode.DRIVING,
    avoidHighways: false,
    avoidTolls: false
  }, callback);
}

function callback(response, status) {
  // See Parsing the Results for
  // the basics of a callback function.
}

Open in new window


However, I need to return a value from the function getDist(). Please let me know how I can do this. Thanks!

might you can use direct calculation

 Math.sqrt((desA-Origin1)*(desA-Origin1)+(desB-Origin2)*(desB-Origin2))

whatever the result is your direct distance.

the formula is use in this is the line equation.....

I have the code that calculates the distance. Its just that I want to return the value rather than just printing it or displaying it in an alert.

var distance=0
for (var i = 0; i < origins.length; i++) { 
        var results = response.rows[i].elements; 
        for (var j = 0; j < results.length; j++) { 
           distance=distance+parseInt(results[j].distance.text); 
        } 
      }
