cesium左側列表定位目標
功能：根據左側列表經緯度等信息的值，進行搜索定位。
列表:
1 點擊清除按鈕可以清空所有input的值
2 點擊查找可以定位到位置，如果輸入的值不在范圍內，會有彈出框提示。
3 每個值，輸入錯誤都有個彈出框，提示你。
記得在合適的位置調用這個locationClick()這個函數哦~~；頁面就是普通的頁面；自己寫就行。如有疑問，請加群討論
下面上代碼
// 左側定位查找
function locationClick() {
locationLon = $("#location_lon").val();
locationLat = $("#location_lat").val();
locationHeight = $("#location_height").val();
locationCenter = Cesium.Cartesian3.fromDegrees(Number(locationLon), Number(locationLat), Number(locationHeight));
locationHeading = Cesium.Math.toRadians($("#location_heading").val());
locationPitch = Cesium.Math.toRadians($("#location_pitch").val());
locationRange = $("#location_range").val();
if (locationLon) {
locationLon = Number(locationLon);
}
if (locationLat) {
locationLat = Number(locationLat);
}
if (locationHeight) {
locationHeight = Number(locationHeight);
} else {

}
// 控制輸入值的范圍

}
viewer.camera.lookAt(locationCenter, new Cesium.HeadingPitchRange(Number(locationHeading), Number(locationPitch), Number(locationRange)));
}
// 定位數據清除
