查看百度地图api里头有说明获取实时经纬度的。
1、成为开发者，获取百度地区秘钥
2、引入百度地图js插件
3、获取经纬度
<script type="text/javascript">
// 初始化地图
var map = new BMap.Map("allmap")
var point = new BMap.Point(116.331398,39.897445)
map.centerAndZoom(point,12)
map.addEventListener("click", function(e){//鼠标点击事件
var pt = e.point
alert(pt.lng + "xxx" + pt.lat)//弹窗经纬度
})</script>
稍等上代码！！
<html><head>
<script type="text/javascript">
function show_coords(event){
var x = event.clientX
var y = event.clientY
var say = document.all("coords")
say.innerHTML = "X:"+x+" Y:"+y
say.style.position = "absolute"
say.style.left = x + 30
say.style.top = y
}
</script>
</head>
<body onmousemove="show_coords(event)">
<p id="coords"></p>
</body>
<html>
希望我的回答对你有用，有用就采纳！！！谢谢！

<!--随便加个图片进来，id为test即可测试-->
鼠标的位置相对窗口坐标是x:<span id="x"></span>--y:<span id="y"></span>
