MapboxTooltip
悬浮提示,鼠标移到目标图层要素时跟随显示,slot 暴露命中要素。
简介
MapboxTooltip 是 Popup 的 hover 模式:鼠标悬浮到 layerId 指定图层的要素上时跟随显示、移出即消失。默认插槽暴露命中要素(feature),可渲染其属性;按 layerId 委托到地图级监听,因此目标图层晚于本组件挂载也能命中。
用法
悬浮圆点图层显示要素信息,slot 取 feature.properties:
<script setup lang="ts">
import type { FeatureCollection } from 'geojson'
const data: FeatureCollection = {
type: 'FeatureCollection',
features: [
{
type: 'Feature',
properties: { name: '天安门', type: '地标' },
geometry: { type: 'Point', coordinates: [116.397, 39.908] }
},
{
type: 'Feature',
properties: { name: '国贸', type: '商圈' },
geometry: { type: 'Point', coordinates: [116.461, 39.909] }
},
{
type: 'Feature',
properties: { name: '中关村', type: '科技园' },
geometry: { type: 'Point', coordinates: [116.316, 39.983] }
}
]
}
</script>
<template>
<div class="h-115 w-full overflow-hidden rounded-(--ui-radius) border border-default">
<MapboxMap
:options="{ style: 'mapbox://styles/mapbox/light-v11', center: [116.39, 39.93], zoom: 11 }"
>
<MapboxLayer
layer-id="poi"

:source="{ type: 'geojson', data }"
:paint="{
'circle-radius': 9,
'circle-color': '#f43f5e',
'circle-stroke-width': 2,
'circle-stroke-color': '#fff'
}"
/>
<!-- 悬浮 poi 图层要素时跟随显示,slot 暴露命中要素 -->
