基于已创建成功的电子地图，添加Control控件。
直接上源码：

<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<!-- 加载OpenLayers 类库 -->
<script type="text/javascript" src="http://www.openlayers.cn/olapi/OpenLayers.js">
</script>
<style>
html, body { width: 100%; height: 100%; margin: 0; padding: 0; }
</style>
<script type="text/javascript">
function init() {
//创建Control对象填充Controls数组
var navigation_control = new OpenLayers.Control.Navigation({});
var controls_array = [//控件数组
navigation_control,
new OpenLayers.Control.PanZoomBar({}),
new OpenLayers.Control.LayerSwitcher({}),
new OpenLayers.Control.Permalink(),
new OpenLayers.Control.MousePosition({})
];
var map=new OpenLayers.Map('test_map',{controls: controls_array});
var wms_layer = new OpenLayers.Layer.WMS(
'WMS Layer Title',
'http://vmap0.tiles.osgeo.org/wms/vmap0',
{layers: 'basic'},
{}
);
map.addLayer(wms_layer);
}
</script>
</head>
<body onload="init()">
<div id="test_map" style="width: 100%;
height: 100%;">
</div>
</body>
</html>
