我正在開發Phone Gap應用程序。在那個應用程序中,我想顯示當前用戶的位置。爲此,我使用了HTML5地理定位。當我點擊獲取位置按鈕時,它不顯示位置。它也不會顯示錯誤。按下獲取位置按鈕後,它只顯示處於選定狀態的按鈕。在HTML5中使用地理位置時不顯示位置

<body>
<button onclick="getLocation()">Get Location</button>
<script>
var x = document.getElementById("demo");
function getLocation() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition, showError);
}
else { x.innerHTML = "Geolocation is not supported by this browser."; }
}
function showPosition(position) {
x.innerHTML = "Latitude: " + position.coords.latitude + "<br>Longitude: " + position.coords.longitude;
}
function showError(error) {
switch (error.code) {
case error.PERMISSION_DENIED:
x.innerHTML = "User denied the request for Geolocation."
break;
case error.POSITION_UNAVAILABLE:
x.innerHTML = "Location information is unavailable."
break;
case error.TIMEOUT:
x.innerHTML = "The request to get user location timed out."
break;
case error.UNKNOWN_ERROR:
x.innerHTML = "An unknown error occurred."
break;
}
}
