Get milepost from road segment

JohnPreston

Hi, I'm trying to get the milepost on a road segment returned from Identity Task (or some other way) in JavaScript. The road segment has Beginning MP and Ending MP as attributes. is there a tool that can calculate (or return) where I clicked on the road? Do you I need to change how road layer is published (using routing)?

John,

something like this:

IdentifyTask.execute (paramters, function (idResults) {
     if (idResults.length > 0) {
          var polyl;
          for(var r=idResults.length-1; r >= 0; r--){
              polyl = idResults.feature.geometry;
              for(var l=polyl.paths.length-1; l >= 0; l--){
                  var pathArray = [];
                  for (j = 0; j < polyl.paths.length; j++){
                      mp = polyl.getPoint(l,j);
                     //mp is a point object so you can use x and y properties on it.
                  }
              }
          }
          
     }
});
