Introduction
The following tutorial guides you through the process of
showing path on Google Map using Html and JavaScript
Use <div> tag with “id” attribute in <body> tag.
<div id="dvMap" >
Use following function in <script> tag.
<script type="text/javascript">
function myMap() {
var mapCanvas =
document.getElementById("dvMap");
var mapOptions = {
center: new
google.maps.LatLng(51.508742,-0.120850),
zoom: 5
};
var map = new google.maps.Map(mapCanvas, mapOptions);
}
</script>
And call it in <body> Like: <body onLoad="myMap()">. This
give you google map after page load.
Use three <input> tag with “id” attribute to enter
source and destination values and one to use as a button
<input id="start"
type="textbox/>
<input id="end"
type="textbox" />
<input type="button"
value="Direction" >
And add one more function in <script> to calculate
route and to show you the path.
function calcRoute() {var latlng = new google.maps.LatLng(23.219104, 72.657137);
var myOptions = {
zoom: 15,
center: latlng,
mapTypeId: google.maps.MapTypeId.SATELLITE
};
var directionsDisplay = new google.maps.DirectionsRenderer();
directionsDisplay.setPanel(document.getElementById("directionsPanel"));
var map = new google.maps.Map(document.getElementById("dvMap"), myOptions);
directionsDisplay.setMap(map);
var directionsService = new google.maps.DirectionsService();
var start = document.getElementById("start").value;
var end = document.getElementById("end").value;
var request = {
origin: start,
destination: end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (result, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(result);
}
});
}
Call this function in onClick attribute in <intput type=”
button”>..
