未捕获的TypeError：JavaScript中的非法调用（地理位置） [英] Uncaught TypeError: Illegal invocation in Javascript (geolocation)

问题描述

在运行代码时，我收到Javascript错误未捕获的TypeError：非法调用

I am getting the Javascript error "Uncaught TypeError: Illegal invocation" when running the code

var nativeGeoloation = window.navigator.geolocation.getCurrentPosition;
nativeGeoloation(function (){ alert("ok")});

我尝试在窗口的上下文中调用代码，但是得到相同的错误：

I have tried calling the code in the context of the window, but get the same error:

nativeGeoloation.call(window,function (){ alert("ok")})

这个问题的背景是我试图访问由另一个JavaScript库（cordova）覆盖的地理定位功能的本机版本

The background of this question is that I am trying to access the native version of the geolocation function that has been overwritten by another javascript library (cordova)

推荐答案

我在Firefox中遇到的错误是：

The error I'm getting in Firefox is:

TypeError：'getCurrentPosition'在未实现接口地理定位的对象上调用。

TypeError: 'getCurrentPosition' called on an object that does not implement interface Geolocation.

将代码更改为：

var nativeGeoloation = window.navigator.geolocation;
nativeGeoloation.getCurrentPosition(function (){ alert("ok")});

（请注意，您还拼写了 nativeGeoloation 不正确，如果您开始正确拼写，可能会在以后造成问题）。

(Note, you've also spelled nativeGeoloation incorrectly which might cause you problems down the road if you start to spell it correctly).
