Blackberry.location API 无法正常工作 [英] Blackberry.location API not working correctly

问题描述

我正在尝试制作 Blackberry 小部件，但遇到了一些麻烦.

I am experimenting with making Blackberry widgets but having a little trouble.

我的第一个试验涉及显示一个按钮，当点击该按钮时，会调用一个 JavaScript 函数，该函数应该提醒手机的纬度和经度.

My first trial involves displaying a button which, when clicked, calls a JavaScript function that should alert the phones latitude and longitude.

函数看起来:

function whereAmI() {
var latitude = blackberry.location.latitude;
var longitude = blackberry.location.longitude;
alert("Lat: "+latitude+", Long: "+longitude);
}

但它只会提醒纬度:0，经度:0".我已经检查过了，我的 GPS 似乎工作正常.

But it only ever alerts "Lat: 0, Long: 0". I've checked and my GPS seems to be working ok.

我在 Curve 8900 上运行 OS 5.*.

I'm running OS 5.* on a Curve 8900.

任何帮助将不胜感激:)

Any help would be appreciated :)

推荐答案

我发现我没有正确签署文件 - 现在我签署了，一切正常.

I discovered that I wasn't signing my files properly - now that I have, everything works fine.

对于小包:

      // called when location object changes
  function locationCB()
  {
     alert("Latitude "  + blackberry.location.latitude);
     alert("Longitude " + blackberry.location.longitude);
     return true;
 }
 // test to see if the blackberry location API is supported
 if( window.blackberry && blackberry.location.GPSSupported)
 {
       document.write("GPS Supported");

       // Set our call back function
       blackberry.location.onLocationUpdate("locationCB()");

       // set to Autonomous mode
       blackberry.location.setAidMode(2);

       //refresh the location
       blackberry.location.refreshLocation();
 }
 else
 {
   document.write("This Device doesn't support the Blackberry Location API");
 }
