Multiple Polyline hatching color change on google v3 map

Question

I need to create several polylines, each with its own color, and their markers are connected to each other, I use google map v3.

For example, I have five markers, and they are all connected to each other through red color polylines. Now I want to show this red polyline in several color schemes, the first polyline in green, the second in blue, the third in black, etc.

Here is my code

<script type='text/javascript'>
var poly;
var map;
var path;
var i = parseInt(0, 10);
var marker;          

function initialize() {
  var chicago = new google.maps.LatLng(41.879535, -87.624333);
  var myOptions = {
    zoom: 7,
    center: chicago,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);
  var polyOptions = {
    strokeColor: '#000000',
    strokeOpacity: 1.0,
    strokeWeight: 3
  }
  poly = new google.maps.Polyline(polyOptions);
  poly.setMap(map);
  // Add a listener for the click event
  google.maps.event.addListener(map, 'click', addLatLng);
}

/**
* Handles click events on a map, and adds a new point to the Polyline.
* @param {MouseEvent} mouseEvent
*/
function addLatLng(event) {
  i++;
  //var path = poly.getPath();
  path = poly.getPath();
  var polyOptions2 = {
    strokeColor: '#FFFFFF',
    strokeOpacity: 1.0,
    strokeWeight: 3
  }
  if (i == 2) {
    poly.setOptions(polyOptions2);

  }
  else {
    polyOptions2.strokeColor = "#FF0000";
    poly.setOptions(polyOptions2);
  }
  path.push(event.latLng);
  // Add a new marker at the new plotted point on the polyline.
  marker = new google.maps.Marker({
    position: event.latLng,
    title: '#' + path.getLength(),
    map: map
  });
}
</script>

Answer 1

Load marker parameters and color for polylines into json array and skip them by creating markers and polylines.

Hope this helps you.

Answer 2

set this piece of code in a loop e.g.

       var colorVariable = ["red","green","blue","yellow","black"];

        for(var a =0;a<=5;a++){
              var polyOptions = {
                strokeColor: colorVariable[a],
                strokeOpacity: 1.0,
                strokeWeight: 2
              }
              poly = new google.maps.Polyline(polyOptions);
              poly.setMap(map);
        }

It works great
