Google maps markers , polyline and window info from array - php

Question

I want to show a polyline with markers and window-info from array point (from a ajax page)
This is index Page codes:
var gmarkers = [];
var map = null;
function initialize() {
var myOptions = {
zoom: 15,
center: new google.maps.LatLng(27.332702, 53.177137),
// mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
}
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50)
});
function myclick(i) {
google.maps.event.trigger(gmarkers[i], "click");
}
function createMarker(latlng, name, html) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
// save the info we need to use later for the side_bar
gmarkers.push(marker);
}
My Ajax Page:
var polylines = [];
var beaches = [
['Bondi Beach',10,15, 4],
['Coogee Beach',11,16, 5],
['Cronulla Beach',13,15, 3],
['Manly Beach',13,17, 2],
['Maroubra Beach',12,10, 1]
];
for (var i = 0; i < beaches.length; i++) {
var beach = beaches[i];
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
var polylines = new google.maps.LatLng(beach[1], beach[2]);
var marker = createMarker(myLatLng,"This place",beach[0])
}
var routes = new google.maps.Polyline({
path: polylines,
strokeColor: "#FF0000",
strokeOpacity: 0.6,
strokeWeight: 4
});
routes.setMap(map);
After I call the Ajax Page , markers add with window-info , but route polyline don't show , where is the problem ?

Yes. polylines is an array here:
var polylines = [];
Here you overwrite it with a single google.maps.LatLng:
var polylines = new google.maps.LatLng(beach[1], beach[2]);
You probably want to do this instead:
polylines.push(new google.maps.LatLng(beach[1], beach[2]));
