【报Bug】app-nvu map include-points 无法显示所有标点

分类:uni-app

产品分类: uniapp/App

PC开发环境操作系统: Windows

PC开发环境操作系统版本号: window 10

HBuilderX类型: 正式

HBuilderX版本号: 2.6.16

手机系统: Android

手机系统版本号: Android 10

手机厂商: 华为

手机机型: huawei meta 20

页面类型: nvue

打包方式: 云端

项目创建方式: HBuilderX

操作步骤:

给定两个标记点的地址,格式化处理两个点的数据,添加颜色什么的其他的属性

预期结果:

标记点都在视野范围内,不需要手动缩放

实际结果:

视野范围内没有这两个点,需要手动调整缩放尺寸才能显示

bug描述:

ip 地址可以用这个例子
[{
latitude: 39.989631,
longitude: 116.481018,
},
{
latitude: 39.9086920000,
longitude: 116.3974770000,
}
];

解决了吗?能分享一下吗?

    没有,目前就把比例尺调到最小。

    回复 y***@163.com: 我是自己计算的scale值你有兴趣可以参考一下,显示不是很精确,但是也算是解决了这个问题https://blog.csdn.net/qq_40792558/article/details/107694048

遗落之章

我的解决方式是自己算出最大和最小的经纬度,再往外扩展一部分,获得一个包裹了所有需要显示的点的矩形,讲矩形的对角两个顶点也加入include-points里,就能很好地显示所有我需要的点了

this.mapCtx.includePoints({
points: this.covers,
padding:[80,80,80,80],
success: (res) => {
util.print('includePoints', res);
},
fail: (err) => {
util.print('includePoints', err);
}
})

nvue页面,同,组件使用includePoints属性没有缩放到点都展示,使用API includePoints提示Can not find map __ERROR
