Multiple Routes in RouteTask

WesleyAskew

I have a route task that is calculating multiple routes simultaneously.   When the user clicks on a map, a stop is added and draws different routes for up to seven different locations.  I have assigned every stop a route name and each route is drawing properly to the appropriate stops.  I need to return the total length of each individual route as a variable for input into a function and was wondering what would be the best way of going about this.  I can successfully alert box the lengths of each route by using: var routeInfo = solveResult.routeResults[0].directions.totalLength; alert(JSON.stringify(routeInfo)); However, the order that each alert message displays starts with the shortest distance routes first.  How do I need to go about identifying which distance is associated with each route?  Thanks in advance.

Thanks for your response.  Yes, I have tried to use this property, however, I cannot seem to get the properties associated with each individual route by name.  I only specify the routeName value for the stops, and am not really sure how this associates with each route segment.  Each route is solved using the following:

routeTask.solve(routeParams);
map.graphics.add(solveResult.routeResults[0].route.setSymbol(routeSymbol));

I can also display the route name and distance in the same alert box using:
var routeLength = solveResult.routeResults[0].directions.totalLength;
var routeName =  solveResult.routeResults[0].routeName;
var routeNameLength = routeName +" "+routeLength;

Do you have any suggestions on how to correspond the name of each route to the length as far as returning a variable is concerned?

You can use a Javascript object in a hastable-like manner. For exemple, inside a loop for your routeResults you could use:

routes[solveResult.routeResults[index].routeName] = solveResult.routeResults[0].directions.totalLength

In the previous sample, index is the for loop indexer and you need to previously declare de routes object (before the loop):

var routes = {};

After that, you can get the total length of a specific route by using its name as an indexer for the routes object:

var distance = routes["your_route_name"];
