Hi Community,
I saw a Mike Tarallo video Qlik Sense - Developer Hub - YouTube (about howto create an extension by javascritp - simple table)
and I have a question.
Is it possibile to calculate a distance from <city> to <city>
or
Is it possible to create a map from <city> to <city>?
Howto?
Hi Fabio,
If you are happy using the Google Maps Javascript api here is some code that will help you calculate the distance between 2 markers :
var start = markerArray[0].getPosition();
var end = markerArray[1].getPosition();
var diff = calculateDistances(start,end).miles;
//--------------------------------------
// Purpose: Calculate the distance between 2 markers
//
//--------------------------------------
function calculateDistances(start,end) {
var stuDistances = {};
//alert(start+' ' +end);
stuDistances.metres = google.maps.geometry.spherical.computeDistanceBetween(start,end); // distance in metres rounded to 1dp --computeDistanceBetween = shortest path
stuDistances.km = Math.round(stuDistances.metres / 1000 *10)/10; // distance in km rounded to 1dp
stuDistances.miles = Math.round(stuDistances.metres / 1000 * 0.6214 *10)/10; // distance in miles rounded to 1dp
return stuDistances;
}
Thanks
Mark
