我试图在web worker中移动navigator.geolocation的代码.

我尝试使用Chrome和Safari,但是"未定义"

var isGPSSupported = navigator.geolocation;

沮丧......他们在规范中说网络工作者应该支持'navigator'对象......

我的代码如下:

index.js

var gpsWorker = new Worker("app/gpsworker.js");

gpsWorker.onmessage = function (e) {
    alert(e.data);
};

gpsWorker.postMessage("Start GPS!");

gpsWorker.onerror = function (e) {
    alert("Error in file: " + e.filename + "\nline: " + e.lineno + "\nDescription: " + e.message);
};

gpsworker.js

self.onmessage = function (e) {
    initGeoLoc();
}

function initGeoLoc() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(function (position) {
            self.postMessage("Got position!");
        });
    } else {
        self.postMessage("GPS is not supported on this platform.");
    }
}

任何有关错误的提示都将不胜感激.
