如何获取地理位置并在单击按钮时将其返回到表单中。
因此，当单击“地理位置”时，会获取我的位置，然后返回输出，以便我稍后可以使用它。 http://jsfiddle.net/Mikki10/as3mg177/1/
地理位置
<html>
<body>
<p>Click the button to get your coordinates.</p>
<button onclick="getLocation()">Get geolocation and put into from</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) {
x.innerHTML = "Latitude: " + position.coords.latitude +
"<br>Longitude: " + position.coords.longitude;
}
</script>
<form action="geo/ruteplanlag.php" method="get">
<input style="width: 98%; margin: 20px auto; text-align: center;" name="startadr" type="text" value="(Custom value like Orlando or geolocation) " />
<input style="width: 98%; margin: 20px auto; text-align: center;" name="slutadr" type="text" value="Miami" />
<div class="buttonHolder">
<input type="submit" value="Start ruteplanlægning">

</form>
</body>
</html>
最佳答案
我现在得到了工作代码。 http://jsfiddle.net/Mikki10/gs5ed5sc/1/
<script type="text/javascript">
function getLocationConstant() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(onGeoSuccess, onGeoError);
} else {
alert("Your browser or device doesn't support Geolocation");
}
}
// If we have a successful location update
function onGeoSuccess(event) {
document.getElementById("Latitude").value = event.coords.latitude;
document.getElementById("Longitude").value = event.coords.longitude;
document.getElementById("Position1").value = event.coords.latitude + ", " + event.coords.longitude;
}
// If something has gone wrong with the geolocation request
function onGeoError(event) {
alert("Error code " + event.code + ". " + event.message);
}
</script>
<form action="geo/ruteplanlag.php" method="get">
<div id="divSample" class="hideClass">Latitude:
<input type="text" id="Latitude" name="Latitude" value="">
<br>
<br>Longitude:
<input type="text" id="Longitude" name="Longitude" value="">
<br>
</div>
<br>Position
<input type="text" id="Position1" name="Position1" value="Miami">
<br>
<br>
<input type="button" value="Get Location" onclick="getLocationConstant()" />
<br>
<br>
<input type="submit" value="Add GPS Location" class=small>
</form>
