OpenLayers3学习(二)–鼠标移动事件
在Web地图应用开发过程中，最常见的事件之一就是使用鼠标在地图上移动，这里我们利用(一)中的地图服务，在此基础上创建一个鼠标移动的事件，代码如下：
<!DOCTYPE html>
<html>
<head>
<title>Tiled ArcGIS MapServer</title>
<link rel="stylesheet" href="http://openlayers.org/en/v3.17.1/css/ol.css" type="text/css">
<script src="http://openlayers.org/en/v3.17.1/build/ol.js"></script>
</head>
<style>
.map
{
width: 1000px;
height: 700px;
}
</style>
<body>
<div id="map" class="map"></div>
<div id="mouse-position"></div>
<script>
var url = 'http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/' +
'Specialty/ESRI_StateCityHighway_USA/MapServer';
var layers = [
new ol.layer.Tile({
source: new ol.source.OSM()
}),
new ol.layer.Tile({
extent: [-13884991, 2870341, -7455066, 6338219],
source: new ol.source.TileArcGISRest({
url: url
})
})
];
//mousePositionControl一定要放在map对象创建之前创建
var mousePositionControl = new ol.control.MousePosition({
coordinateFormat: ol.coordinate.createStringXY(4),
className: 'custom-mouse-position',
target: document.getElementById('mouse-position'),
undefinedHTML: ' '
});
var map = new ol.Map({
layers: layers,
target: 'map',
view: new ol.View({
center: [-10997148, 4569099],
zoom: 4
}),
controls:ol.control.defaults().extend([mousePositionControl])
});
</script>
</body>
