MAP to pass the latitude & longitude and moving marker

Here ,I set the time interval for this script but its not working.Find my mistake & help to trieve 

Thanks by advance 

 ---------------------------------------------------------------------------------------------

var src_city1 = document.getElementById("src_city1").value;

var src_city2 = document.getElementById("src_city").value;

var map, marker;

var startPos = [src_city1,src_city2];

var speed = 50; // km/h

var delay = 100;

function animateMarker(marker, coords, km_h)

{

var target = 0;

var km_h = km_h || 50;

coords.push([startPos[0], startPos[1]]);

var spherical;

var computeDistanceBetween;

function goToPoint()

{

var lat = marker.position.lat();

var lng = marker.position.lng();

var step = (km_h * 1000 * delay) / 3600000;

var dest = new google.maps.LatLng(

coords[target][0], coords[target][1]);

var distance = google.maps.geometry.spherical.computeDistanceBetween(dest, marker.position);

var numStep = distance / step;

var i = 0;

var deltaLat = (coords[target][0] - lat) / numStep;

var deltaLng = (coords[target][1] - lng) / numStep;

function moveMarker()

{

lat += deltaLat;

lng += deltaLng;

i += step;

if (i < distance)

{

marker.setPosition(new google.maps.LatLng(lat, lng));

setTimeout(moveMarker, delay);

}

else

{ marker.setPosition(dest);

target++;

if (target == coords.length){ target = 0; }

setTimeout(goToPoint, delay);

}

}

moveMarker();

}

goToPoint();

}

function initialize()

{

var myOptions = {

zoom: 16,

center: new google.maps.LatLng(src_city1,src_city2),

mapTypeId: google.maps.MapTypeId.ROADMAP

};

map = new google.maps.Map(document.getElementById("dvMap"), myOptions);

var icon = "Markers/letter_m.png";

marker = new google.maps.Marker({

position: new google.maps.LatLng(startPos[0], startPos[1]),

map: map,

icon:icon

});

google.maps.event.addListenerOnce(map, 'idle', function()

{

setInterval(marker, [

[startPos]

], 5000);

});

}

initialize();

Hi Karthika,

 

There are differant ways to achieve it, one way is update your maker postion on map with an ajax and pass updated lat/long to the map and create animation on your marker which create a feel of moving.
