尝试使用地理位置打印当前位置地址

我正在尝试使用地理位置打印当前位置地址，但没有任何内容正在打印在屏幕上。你能帮我吗我在这里错了吗？尝试使用地理位置打印当前位置地址

或者有没有其他方法可以将当前地址存储在变量中？

<!DOCTYPE html> 
<html> 
<body> 

<button onclick="getLocation()">Try It</button> 

<p id="demo"></p> 

<script> 

var x = document.getElementById("demo"); 

function getLocation() { 
    if (navigator.geolocation) { 
     navigator.geolocation.getCurrentPosition(showPosition); 
    } else { 
     x.innerHTML = "Geolocation is not supported by this browser."; 
    } 
} 

function showPosition(position) { 

var request = new XMLHttpRequest(); 
var method = 'GET'; 
var url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='+position.coords.latitude+','+position.coords.longitude; 
var async = true; 

request.open(method, url, async); 

request.onreadystatechange = function(){ 

var data = JSON.parse(request.responseText); 
var address = data.results[0]; 
x.innerHTML = address.formatted_address;   
     }; 
} 
</script> 

</body> 
</html>

这应该工作：JSFIDDLE

你失踪request.send();，也没有检查request.readyState

<!DOCTYPE html> 
<html> 

    <body> 

    <button onclick="getLocation()">Try It</button> 

    <p id="demo"></p> 

    <script> 
     var x = document.getElementById("demo"); 

     function getLocation() { 
     if (navigator.geolocation) { 
      navigator.geolocation.getCurrentPosition(showPosition); 
     } else { 
      x.innerHTML = "Geolocation is not supported by this browser."; 
     } 
     } 

     function showPosition(position) { 

     var request = new XMLHttpRequest(); 
     var method = 'GET'; 
     var url = '//maps.googleapis.com/maps/api/geocode/json?latlng=' + position.coords.latitude + ',' + position.coords.longitude; 
     var async = true; 

     request.open(method, url, async); 
     request.setRequestHeader('Accept', 'application/json'); 
     request.onreadystatechange = function() { 
      if (request.readyState == XMLHttpRequest.DONE) { 
      var data = JSON.parse(request.responseText); 
      var address = data.results[0]; 
      x.innerHTML = address.formatted_address; 
      } 
     }; 
     request.send(); 
     } 

    </script> 

    </body> 

</html>
