cesium左侧列表定位目标

功能：根据左侧列表经纬度等信息的值，进行搜索定位。

列表:

1 点击清除按钮可以清空所有input的值

2 点击查找可以定位到位置，如果输入的值不在范围内，会有弹出框提示。

3 每个值，输入错误都有个弹出框，提示你。

下面上代码

75     // 定位数据清除
76     $(function () {

78             $("#location_lon").val("");
79             $("#location_lat").val("");
80             $("#location_height").val("");
81             $("#location_heading").val("");
82             $("#location_pitch").val("");
83             $("#location_range").val("");
84         });
85     });

记得在合适的位置调用这个locationClick()这个函数哦~~；页面就是普通的页面；自己写就行。如有疑问，请加群讨论
