Question

我在这里已多次阅读同样的问题并修复了最重复的解决方案，并添加了w3c规范中提到的错误处理程序，但它没有给我任何例外或错误，也没有结果。我不知道该怎么做？

这是我写的完整代码！

<!DOCTYPE HTML>

<head>
    <title> HTML5 Egypt User Group - Demos</title>
<script src="http://maps.google.com/maps/api/js?sensor=false">

<script type="text/javascript">

var lastLat; 
    var lastLong; 
function updateStatus(message) { 
        document.getElementById("status").innerHTML = message; 
    } 

function loadDemo() { 
    if(navigator.geolocation) { 
        updateStatus("W3C Geolocation is supported in your browser."); 
        navigator.geolocation.watchPosition(updateLocation, 
                                            handleLocationError, 
                                            {maximumAge:20000}); 
    } 
} 

window.addEventListener("load", loadDemo, true); 



function handleLocationError(error) { 
  switch (error.code) { 
case 0: 
updateStatus("There was an error while retrieving your location: " +  
                error.message); 
break; 

case 1: 
updateStatus("The user prevented this page from retrieving a location."); 
break; 

case 2: 
updateStatus("The browser was unable to determine your location: " +  
              error.message); 
break; 

case 3: 
updateStatus("The browser timed out before retrieving the location."); 
break; 
  } 
} 
function updateLocation(position) { 
    var latitude = position.coords.latitude; 
    var longitude = position.coords.longitude; 
    var accuracy = position.coords.accuracy; 
    var timestamp = position.timestamp; 

    document.getElementById("latitude").innerHTML = latitude; 
    document.getElementById("longitude").innerHTML = longitude; 
    document.getElementById("accuracy").innerHTML = accuracy; 
    document.getElementById("timestamp").innerHTML = timestamp; 
      // sanity test... don't calculate distance if accuracy 
    // value too large 
    if (accuracy >= 500) { 
        updateStatus("Need more accurate values to calculate distance."); 
        return; 
}
} 

     </script>

     <body> 
 <button onclick="loadDemo()"> loadDemo()</button>

您正在使用输入控件。尝试设置值而不是innerHTML。

function updateLocation(position) { 
    var latitude = position.coords.latitude; 
    var longitude = position.coords.longitude; 
    var accuracy = position.coords.accuracy; 
    var timestamp = position.timestamp; 

    document.getElementById("latitude").value = latitude;
    document.getElementById("longitude").value = longitude;
    document.getElementById("accuracy").value = accuracy;
    document.getElementById("timestamp").value = timestamp; 
      // sanity test... don't calculate distance if accuracy 
    // value too large 
    if (accuracy >= 500) { 
        updateStatus("Need more accurate values to calculate distance."); 
        return; 
    }
}

W3C地理定位API没有错误没有期望也没有结果
