急求。。asp.net开发wap网页获取当前手机所在的坐标
急求。。asp.net开发wap网页获取当前手机所在的坐标位置或者区域商圈位置 --------------------编程问答-------------------- GPS信息吗?如果是的话 用JavaScript就可以获取了..地址
代码如下
--------------------编程问答-------------------- 必须是html5 --------------------编程问答-------------------- 你的这个获取的地址不够精准啊 --------------------编程问答-------------------- 那你给点例子我看看 --------------------编程问答-------------------- 不够精准?你是用电脑测试还是手机测试?

<p id="demo">点击这个按钮，获得您的位置：</p>

我手机测试 误差不过十米左右.. --------------------编程问答-------------------- 手机测试 误差已经到了几百米 --------------------编程问答-------------------- 我估计你手机一定是小米之类的的渣渣
补充：.NET技术 , ASP.NET
