Google maps: Change colour of polyline when clicked, but change colour back to original colour when second polyline is clicked

I have a site which has numerous hiking paths displayed as polylines in Google maps. All polylines have Strokecolor green as default. I would like it that when a polyline is clicked, the polyline colour turns red. It should remain red until a second (different) polyline is clicked. The first polyline should then turn back to green and the second polyline turns red.



I have searched and search and tried numerous solutions, but none work.



The "test" code I have submitted is "clean" without any of my failed attempts.

          add a global var .. previous path and assign the object value when you click an object then change the color for th actual object and restore th color for the prev_path object



          var prev_path;


          flightPath.addListener('click', function(event)

          this.setOptions(
          zIndex: 10,
          strokeColor: your_strokeColor,
          strokeOpacity: your_strokeOpacity,
          strokeWeight: your__strokeWeight
          icons: [
          icon: pathSymbol,
          offset: '0',
          repeat: '40px',
          zIndex: 10
          ],
          );

          if (prevPath)
          prev_path.setOptions(
          zIndex: 10,
          strokeColor: your_color_for_not_select_strokeColor,
          strokeOpacity: your_color_for_not_select_strokeOpacity,
          strokeWeight: your_color_for_not_select_strokeWeight
          );


          prev_path = this;

          );

          • Perfect. I have updated your code with an if - else there is no prev_path. Only once prev_path is assigned a value should it run through that code

          One option would be to keep references to all the polylines, process through that list setting them back to the default value on a click, then set the current polyline to the "selected color.



          var polylines = ;
          function addPath(props)
          flightPath = new google.maps.Polyline(
          path: props.path,
          strokeColor: props.strokeColor,
          strokeOpacity: props.strokeOpacity,
          strokeWeight: props.strokeWeight,
          normalOptions:
          strokeColor: props.strokeColor,
          ,
          selectedOptions:
          strokeColor: "red",

          );
          flightPath.setMap(map);
          polylines.push(flightPath);

          flightPath.addListener('mouseover', function(event)
          this.setOptions(
          zIndex: 10,
          icons: [
          icon: pathSymbol,
          offset: '0',
          repeat: '40px',
          zIndex: 10
          ],
          );
          );

          flightPath.addListener('mouseout', function(event)
          this.setOptions(
          zIndex: 0,
          icons: [
          visible: false,
          zIndex: 0
          ],
          );
          );
          flightPath.addListener('click', function(event)
          for (var i=0; i<polylines.length; i++)
          polylines[i].setOptions(polylines[i].normalOptions)

          this.setOptions(this.selectedOptions);
          )

          add a global var .. previous path and assign the object value when you click an object then change the color for th actual object and restore th color for the prev_path object



          var prev_path;


          flightPath.addListener('click', function(event)

          this.setOptions(
          zIndex: 10,
          strokeColor: your_strokeColor,

          • Perfect. I have updated your code with an if - else there is no prev_path. Only once prev_path is assigned a value should it run through that code

          One option would be to keep references to all the polylines, process through that list setting them back to the default value on a click, then set the current polyline to the "selected color.



          var polylines = ;
          function addPath(props)
          flightPath = new google.maps.Polyline(
          path: props.path,
          strokeColor: props.strokeColor,
          strokeOpacity: props.strokeOpacity,
          strokeWeight: props.strokeWeight,
          normalOptions:
          strokeColor: props.strokeColor,
          ,
          selectedOptions:
          strokeColor: "red",

          );
          flightPath.setMap(map);
          polylines.push(flightPath);

          flightPath.addListener('mouseover', function(event)
          this.setOptions(
          zIndex: 10,
          icons: [
          icon: pathSymbol,
          offset: '0',
          repeat: '40px',
          zIndex: 10
          ],
          );
          );

          flightPath.addListener('mouseout', function(event)
          this.setOptions(
          zIndex: 0,
          icons: [
          visible: false,
          zIndex: 0
          ],
          );
          );
          flightPath.addListener('click', function(event)
          for (var i=0; i<polylines.length; i++)
          polylines[i].setOptions(polylines[i].normalOptions)

          • This is great and has helped me with another problem. But I'll use the solution from scaisEdge - it's a little simpler. Thank you.

          One option would be to keep references to all the polylines, process through that list setting them back to the default value on a click, then set the current polyline to the "selected color.



          var polylines = ;
          function addPath(props)
          flightPath = new google.maps.Polyline(
          path: props.path,
          strokeColor: props.strokeColor,

          strokeWeight: props.strokeWeight,
          normalOptions:
          strokeColor: props.strokeColor,
          ,
          selectedOptions:
          strokeColor: "red",

          );
          flightPath.setMap(map);
          polylines.push(flightPath);

          flightPath.addListener('mouseover', function(event)
          this.setOptions(
          zIndex: 10,
          icons: [

          zIndex: 10
          ],
          );
          );

          flightPath.addListener('mouseout', function(event)
