mapbox样式修改

1.

mapbox直接用class名无法修改样式, 可以添加 :deep 来修改样式

2.

 map.value.getStyle().layers

这行代码可以获取页面中所有图层,可以判断图层id来做相应操作

3.

map.value.setLayoutProperty(layer.id, 'visibility', 'visible')//图层显示

map.value.setLayoutProperty(layer.id, 'visibility', 'none');//图层隐藏

layer.id为map.value.addlayer里的id

4.

报错总结: v-for 循环会影响到dom的生成, for循环了 会出现多个dom,你ref参数 由原来的 一个 变成了多个
方法一: 在for循环里生成echarts 使用ref绑定, 获取时需要[0]
方法二: 在for循环里生成echarts 使用动态ref绑定, 在pushBtnList里面赋值给 echarts绑定的值,并且不需要下标取值

持续更新…
