根据腾讯地图API，以图文的方式一步一步的来说明如何获取详细的位置信息数据。具体参考腾讯地图Webservice API的简介。腾讯地图WebService API
第一步：申请开发者密钥（key）申请密钥
我选择的应用类型为浏览器类型（调用Javascript API、JSONP调用WebService API、静态图API等）。
填写完成提交好既可以获取属于自己的Key。
第二步：Key获取到了，下面就要通过ajax请求获取位置信息了
首先跟大家说一下此接口都可以获取那些信息，以及需要传哪些参数。简单来说就是输入坐标返回地理位置信息和附近poi列表（POI是“Point of Interest”的缩写，可以翻译成“信息点”，每个POI包含四方面信息，名称、类别、经度纬度、附近的酒店饭店商铺等信息）。

以上就是返回的参数信息，具体的参数介绍：http://lbs.qq.com/webservice_v1/guide-gcoder.html
下面呢，就写一下如何发送ajxa请求，当然这个请求是jsonp的跨域请求。
1 var data={
2 location:"39.984154,116.307490",
3 /*换成自己申请的key*/
4 key:"OB4BZ-D4W3U-B7VVO-4PJWW-6TKDJ-WPB77",
5 get_poi:0
6 }
7 var url="http://apis.map.qq.com/ws/geocoder/v1/?";
8 data.output="jsonp";
9 $.ajax({
10 type:"get",
11 dataType:'jsonp',
12 data:data,
13 jsonp:"callback",
14 jsonpCallback:"QQmap",
15 url:url,
16 success:function(json){
17 /*json对象转为文本 var aToStr=JSON.stringify(a);*/
18 var toStr = JSON.stringify(json);
19 toStr=getFormatJsonStrFromString(toStr);
20 /*调用业务处理程序*/
21 suggestion_example&&suggestion_example($show,url_list,toStr);
22 },
23 error : function(err){alert("服务端错误，请刷新浏览器后重试")}
24
25 }
这样在跨域得到的数据就可以在ajax请求的【json】中获取了。
