如果用户拒绝在 Firefox 中共享地理位置，则永远不会调用函数失败 [英] function fail never called if user declines to share geolocation in firefox

问题描述

所以我有这个 javascript 代码.在 safari 和 chrome 中，如果用户拒绝共享位置，它应该会失败；然而，在 Firefox 中，它没有.

So I have this javascript code. In safari and chrome, if user declines to share location, it goes to fail function as it should; however, in Firefox, it does not.

任何帮助表示赞赏.

function initGeolocation()
{
    if( navigator.geolocation )
    {          
          // Call getCurrentPosition with success and failure callbacks
          navigator.geolocation.getCurrentPosition( success, fail );
    }
    else
    {
          alert("Sorry, your browser does not support geolocation services.");
    }
}

 var map;
 function success(position)
 {

     var longIDText = document.getElementById('longID');
     var latIDText = document.getElementById('latID');
     longIDText.value = position.coords.longitude;
     latIDText.value = position.coords.latitude;
     document.getElementById('coordSubmitID').click();
  }

  function fail(error)
  {
          alert("FAAAAAAAAAAIIIIIIIIIL")
          var zip_code ;
          while (true){
              // Could not obtain location

              zip_code = prompt("Please enter your current address or zip code","");


              if ( zip_code == "" ) {
                  alert(zip_code +" is not a valid address. Please try again.");
              } 
              else{
                break;
              }
          }
          var zipIDText = document.getElementById('zipID');
          zipIDText.value = zip_code;
          document.getElementById('coordSubmitID').click();
  }

推荐答案

对于 Firefox it 似乎 PERMISSION_DENIED仅在选择从不共享"时引发；如果对话框被关闭或选择不是现在"，实际上什么也不会发生 - 即使在 mozillas geolocation demo 如果您关闭权限 UI，则什么也不会发生.

For Firefox it seems that PERMISSION_DENIED is raised only if "Never share" is selected; if the dialog is dismissed or "Not now" is selected, effectively nothing happens - even on mozillas geolocation demo if you dismiss the permissions UI nothing happens.

这意味着 getCurrentPosition 可以返回，因为用户关闭了确认 UI，或者因为它成功启动了异步请求 - 似乎没有办法区分两者.

This means that getCurrentPosition can return either because the user closed the confirmation UI, or because it successfully started it asynchronous request - there doesn't appear to be a way to discriminate between the two.
