今天我們將把html5的geolocation結合google maps開發一個小的應用。google maps的api地址：https://developers.google.com/maps/documentation/javascript/?hl=zh-CN。復制代碼
代碼如下:
<body>
<div>
</div>
</body>
復制代碼
代碼如下:
<script type="text/javascript">
var map;
var browserSupport = false;
var attempts = 0;
$(document).ready(function () {
//初始化地圖
InitMap();
//定位
getLocation();
//定位跟蹤
watchLocation();
});
function InitMap() {
/* Set all of the options for the map */
var options = {
};
/* Create a new Map for the application */
map = new google.maps.Map($('#map')[0], options);
}
/*
* If the W3C Geolocation object is available then get the current
* location, otherwise report the problem
*/
function getLocation() {
}
function watchLocation() {
}
/* Plot the location on the map and zoom to it */
function plotLocation(position) {
}
/* Report any errors using this function */
function reportProblem(e) {
}
</script>
復制代碼
代碼如下:
function InitMap() {
/* Set all of the options for the map */
var options = {
zoom: 4,
center: new google.maps.LatLng(38.6201, -90.2003),
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: true,
mapTypeControlOptions: {
style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR,
position: google.maps.ControlPosition.BOTTOM_CENTER
},
panControl: true,
panControlOptions: {
position: google.maps.ControlPosition.TOP_RIGHT
},
zoomControl: true,
zoomControlOptions: {
style: google.maps.ZoomControlStyle.LARGE,
position: google.maps.ControlPosition.LEFT_CENTER
},
scaleControl: true,
scaleControlOptions: {
position: google.maps.ControlPosition.BOTTOM_LEFT
},
streetViewControl: true,
streetViewControlOptions: {
position: google.maps.ControlPosition.LEFT_TOP
}
};
/* Create a new Map for the application */
map = new google.maps.Map($('#map')[0], options);
}
復制代碼
代碼如下:
function getLocation() {
/* Check if the browser supports the W3C Geolocation API */
if (navigator.geolocation) {
browserSupport = true;
navigator.geolocation.getCurrentPosition(plotLocation, reportProblem, { timeout: 45000 });
} else {
reportProblem();
}
}
function watchLocation() {
/* Check if the browser supports the W3C Geolocation API */
if (navigator.geolocation) {
browserSupport = true;
navigator.geolocation.watchPosition(plotLocation, reportProblem, { timeout: 45000 });
} else {
reportProblem();
}
}
復制代碼
代碼如下:
function plotLocation(position) {
attempts = 0;
var point = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var marker = new google.maps.Marker({
position: point
});
marker.setMap(map);
map.setCenter(point);
map.setZoom(15);
}
