问题描述
我正在尝试html5的地理定位功能。这是我的代码：
Hi,
I am trying out the geolocation feature of html5. Here is my code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
var lat = document.getElementById("latitude");
var lon = document.getElementById("latitude");
function getLocation()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition(showPosition);
}
else
{
x.innerHTML = "Geolocation is not supported by this browser.";
}
}
function showPosition(position)
{
lat.value = position.coords.latitude;
lon.value = position.coords.longitude;
}
</script>
</head>
<body>
<form>
<button id="GetGeoLocation" onclick="getLocation()">Get Geo Location</button><br/>
Latitude: <label id="latitude" /> <br/>
Longitude: <label id="longitude" />
</form>
</body>
</html>
点击按钮，代码无法到达javascript。
谢谢

推荐答案
我刚做了一个测试你的代码和java
脚本文件被调用
I just did a test on your code and the java
script files is getting called
function getLocation() {
alert("GetLocaiton Function called");
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(showPosition);
}
else {
x.innerHTML = "Geolocation is not supported by this browser.";
}
}
如果你的其他部分，你有x.innerHTML但没有名为'的元素'代码中的x'？
if your else part, you have x.innerHTML but there is no element called 'x' in your code ?
