【中文标题】使用 phonegap eclipse 的 Android 的 HTML5 地理定位应用程序【英文标题】：HTML5 geolocation app for Android using phonegap eclipse 【发布时间】：2013-06-26 17:02:26 【问题描述】：

我无法运行这个适用于 android 的 html5 地理定位应用程序。该应用程序在我的桌面上的 Firefox 浏览器中运行良好，但是一旦我使用 Eclipse - PhoneGap 编译它，地理定位按钮不会执行命令 document.write，我尝试使用 alert() 以及 console.log()，但没有阳性结果。

代码如下，如果我错过了设置任何用于地理定位的电话传感器，请指点我吗？

Below is the code:

【问题讨论】：

【参考方案1】：

document.write 似乎是您的问题的原因，而不是地理定位失败，当然假设您在 AndroidManifest.xml 中有足够的权限：

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />

顺便说一句，您的源代码中有一个错字</headd> 应该是</head>。

您还应该真正使用$(document).on("deviceready") 而不是$(document).ready() 和Phonegap，因为'ready' 事件仅表示DOM 已准备好，而'deviceready' 表示Phonegap 已完全加载。

【讨论】：

非常感谢，现在可以使用了！至于你关于使用 $(document).on("deviceready") 而不是 $(document).ready() 的建议，调用的第一行应该是这样的吗？当我将其更改为 $(document).on("deviceready", function () 按钮不再起作用... 很高兴我能提供帮助 :-) 请接受我的回答，以便其他人知道它已得到回答。对于 deviceready 事件，您的语法看起来是正确的，所以我不确定为什么它不起作用 - 也许尝试使用 bind：$(document).bind("deviceready",function()...); deviceready 事件的Phonegap 文档是here，如果它有帮助...
