之前有朋友问，如何在Skyline里面实现FlyTo定位到目标点之后触发的事件函数呢？
下面的这段代码，就可以帮你解决这个问题。

function CreateSGObj() {
var obj = $("sgworld");
if (obj == null) {
obj = document.createElement('object');
document.body.appendChild(obj);
obj.name = "sgworld";
obj.id = "sgworld";
obj.classid = "CLSID:3a4f9197-65a8-11d5-85c1-0001023952c1";
}
return obj;
}
function $(id) {
return window.document.getElementById(id);
} var tkey = null;
function SetStart() {
var SGWorld = CreateSGObj();
tkey = window.setInterval(OnFrame, 100);
}
function SetEnd() {
var SGWorld = CreateSGObj();
window.clearInterval(tkey);
} var x = 0, y = 0;
function OnFrame() {
var SGWorld = CreateSGObj();
var npos = SGWorld.Navigate.GetPosition(3);
var res = window.document.getElementById("result");
res.innerHTML = "";
if (x == npos.X && y == npos.Y) {
res.innerHTML ="飞行结束:)"+ "X:" + npos.X + "______Y:" + npos.Y;
}
else {
x = npos.X;
y = npos.Y;
res.innerHTML = ":(正在飞行中....";
}
}
</script>
</head>
<body>
<table>
<tr>
<td colspan="4">
<input id="Button3" type="button" value="开始监测" onclick="SetStart()" />
<input id="Button1" type="button" value="结束监测" onclick="SetEnd()" />
</td>
</tr>
<tr>
<td colspan="4">
相机观察点坐标
</td>
<td>
<div id="result">
</div>
</td>
</tr>
</table>
</body>
</html>
希望上面的方法能够解决你遇到的问题，或者带来一些启发。
如果使用的是SkylineGlobe 6.5.1的版本，实现上面的功能就更简单了，可以直接调用OnObjectAction方法来实现；
