geoLocation.GetCurrentPosition always fails in IE

The script below works fine in FireFox and Chrome, but in Internet Explorer 11, it always fails (with POSITION_UNAVAILABLE).

I have set the browser to allow requests for position, and I agree to the prompt the browser presents me when requesting permission.

I'm almost certain that this worked fine a few months ago when I was last experimenting with it. What could I be missing as far as IE's settings?

<script type="text/javascript">
    $(document).ready(function () {
        if (Modernizr.geolocation)
        {
            navigator.geolocation.getCurrentPosition(positionSuccess, positionError, { enableHighAccuracy: true, maximumAge: 60000, timeout: 10000 })
        }
        else
        {
            $("#GeoError").html("Unable to retrieve current position.")
        }
    });

    function positionSuccess(position)
    {
        $("#Latitude").val(position.coords.latitude);
        $("#Longitude").val(position.coords.longitude);
    }

    function positionError(error)
    {
        var message = "";

        // Check for known errors
        switch (error.code) {
            case error.PERMISSION_DENIED:
                message = "This website does not have your permission to use the Geolocation API";
                break;
            case error.POSITION_UNAVAILABLE:
                message = "Your current position could not be determined.";
                break;
            case error.PERMISSION_DENIED_TIMEOUT:
                message = "Your current position could not be determined within the specified timeout period.";
                break;
        }

        // If it's an unknown error, build a message that includes 
        // information that helps identify the situation, so that 
        // the error handler can be updated.
        if (message == "") {
            var strErrorCode = error.code.toString();
            message = "Your position could not be determined due to " +
                      "an unknown error (Code: " + strErrorCode + ").";
        }

        $("#GeoError").html(message)
    }
</script>

Also, I get the same failure in IE11 when I try http://html5demos.com/geo, where both FireFox and Chrome work fine.

回答1:

Does you enable the Location Service?

I have had the same issue, it worked after I enabled the Location Service in my windows 2016.

This page shows how to enable the Location Service in windows 10.

回答2:

I have had the same issue in IE11 only. I had to set enableHighAccuracy to false to get it to work. Once I did that IE worked as expected.

回答3:

In Internet Options, click on the Privacy tab. Uncheck the Never allow websites to request your physical location box, hit on OK.

After making these changes, the http://html5demos.com/geo now worked for me. Initially it didn't.

aha, just discovered something. Chrome apparently uses the WIFI access points to help finding the location.
