有針對使用谷歌的地圖API和自定義控制設置一個選項,這裏是我發現的代碼片段:
var map;
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
/**
* The ZoomControl adds +/- button for the map
*
*/
function ZoomControl(controlDiv, map) {
// Creating divs & styles for custom zoom control
controlDiv.style.padding = '5px';
// Set CSS for the control wrapper
var controlWrapper = document.createElement('div');
controlWrapper.style.backgroundColor = 'white';
controlWrapper.style.borderStyle = 'solid';
controlWrapper.style.borderColor = 'gray';
controlWrapper.style.borderWidth = '1px';
controlWrapper.style.cursor = 'pointer';
controlWrapper.style.textAlign = 'center';
controlWrapper.style.width = '32px';
controlWrapper.style.height = '64px';
controlDiv.appendChild(controlWrapper);
// Set CSS for the zoomIn
var zoomInButton = document.createElement('div');
zoomInButton.style.width = '32px';
zoomInButton.style.height = '32px';
/* Change this to be the .png image you want to use */
zoomInButton.style.backgroundImage = 'url("http://placehold.it/32/00ff00")';
controlWrapper.appendChild(zoomInButton);
// Set CSS for the zoomOut
var zoomOutButton = document.createElement('div');
zoomOutButton.style.width = '32px';
zoomOutButton.style.height = '32px';
/* Change this to be the .png image you want to use */
zoomOutButton.style.backgroundImage = 'url("http://placehold.it/32/0000ff")';
controlWrapper.appendChild(zoomOutButton);
// Setup the click event listener - zoomIn
google.maps.event.addDomListener(zoomInButton, 'click', function() {
map.setZoom(map.getZoom() + 1);
});
// Setup the click event listener - zoomOut
google.maps.event.addDomListener(zoomOutButton, 'click', function() {
map.setZoom(map.getZoom() - 1);
});
}
function initialize() {
var mapDiv = document.getElementById('map-canvas');
var mapOptions = {
zoom: 12,
center: chicago,
/* Disabling default UI widgets */
disableDefaultUI: true
}
map = new google.maps.Map(mapDiv, mapOptions);
// Create the DIV to hold the control and call the ZoomControl() constructor
// passing in this DIV.
var zoomControlDiv = document.createElement('div');
var zoomControl = new ZoomControl(zoomControlDiv, map);
zoomControlDiv.index = 1;
map.controls[google.maps.ControlPosition.TOP_LEFT].push(zoomControlDiv);
}
initialize();
