Offers methods
ApplicationProgrammingInterface
Uses methods without
knowing the code

4. What's an API?
Application Programming Interface
Pros:
● Easy to use, if API is well documented
● Not everybody has to programm eyerything
(reinvent the wheel)
● Mashups are easier to create
Cons:
● You don´t know exactly how it works
● It´s Google!

13. Google Custom Search APIs
google.setOnLoadCallback(function() {
var customSearchControl =
new google.search.SearchControl(ID)
customSearchControl.setResultSetSize(switchTo);
var options = new google.search.DrawOptions();
options.setSearchFormRoot('cse-search-form');
customSearchControl.draw('cse', options);
}, true);
<div id="cse" style="width:100%;"></div>

26. Connection and adding Map
<script type="text/JavaScript">
var map;
function initialize() {
var latlng =
new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById
("map_canvas"), myOptions);
}
</script>
<body onload="initialize()">
<div id="map_canvas" style="width:1000px;
height:500px"></div>
</body>

27. Adding Mouse Event Listeners
var map;
var marker;
function initialize() {
var latlng =
new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById
("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click',
function(event) {
placeMarker(event.latLng);
});
}
27 Web Technologies

28. Adding Mouse Event Listener
function placeMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map
});
map.setCenter(location);
}
28 Web Technologies

29. Adding Information of tours
function attachMessage(marker) {
var message = document.getElementById("description").value;
var infowindow = new google.maps.InfoWindow(
{ content: message,
size: new google.maps.Size(50,50)
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
}
<body onload="initialize()">
<div id="map_canvas" style="width:1000px; height:500px"></div>
<input type="text" name="description" value=""
id="description" size="20">
</body>
