vue+leaflet+element实现轨迹回放并且加可控制的进度条

对于您的问题，我可以回答。您可以通过Vue Leaflet Element库来实现轨迹回放，并添加可控制的进度条。该库是一个基于Vue.js和Leaflet的地图组件，提供了众多的地图功能和扩展性。您可以使用Leaflet的GeoJSON插件来加载轨迹数据，并使用Vue.js组件库实现进度条。希望这个答案能对您有所帮助。如果您有任何其他的问题，请随时问我。

vue+leaflet+element实现轨迹回放并且加可控制的进度条，用代码体现

可以使用Vue-leaflet和Vue2-leaflet-trackplayback库来实现轨迹回放，并使用Vue-slider-component来加入进度条控制。以下是代码示例：

<template>
<div id="map-container">
<l-map :zoom="zoom" :center="center">
<l-tile-layer :url="url"></l-tile-layer>
<l-track-playback :geojson="geojson" :options="options" ref="trackplayback"></l-track-playback>
<vue-slider :value="value" :min="0" :max="max" v-model="value" @change="handleSliderChange"></vue-slider>
</l-map>
</div>
</template>

<script>
import L from 'leaflet';
import 'leaflet/dist/leaflet.css';
import 'leaflet-trackplayback';
import 'vue-slider-component/theme/default.css';
import VueSlider from 'vue-slider-component';

export default {
name: 'map',
components: {
'l-map': L.Map,
'l-tile-layer': L.TileLayer,
'l-track-playback': L.TrackPlayback,
'vue-slider': VueSlider,
},
data() {
return {
zoom: 13,
center: [39.9, 116.4],
url: 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
geojson: {
type: 'Feature',
properties: {},
geometry: {
type: 'LineString',
coordinates: [[116.4, 39.9], [116.41, 39.91], [116.42, 39.92], [116.43, 39.93], [116.44, 39.94], [116.45, 39.95], [116.46, 39.96], [116.47, 39.97], [116.48, 39.98], [116.49, 39.99]]
}
},
options: {
markers: true,
autoplay: false,
playControl: true,
follow: true,
speed: 500,
markerOptions: {
icon: L.icon({iconUrl: 'marker.png', iconSize: [40, 40]})
},
},
value: 0,
max: 9,
};
},
methods: {
handleSliderChange(value) {
this.$refs.trackplayback.goTo(value);
}
},
};
</script>

vue+leaflet+element实现轨迹回放(加可控制的进度条)，写一个代码实例

好的，以下是代码示例，希望能对您有所帮助：

<template>
<div class="map-container">
<el-map ref="map" :zoom="zoom" :center="center" style="height: 100%">
<el-tile-layer :url="tileLayerUrl"></el-tile-layer>
<el-polyline :path="polylinePath" :editable="editable" :weight="weight" :color="color"></el-polyline>
</el-map>
<el-slider v-model="progress" :min="0" :max="totalSeconds" :show-input="true" :disabled="!playable"></el-slider>
<el-button @click="togglePlay" :icon="playable ? playing ? 'el-icon-pause' : 'el-icon-caret-right' : 'el-icon-video-play'" :disabled="!playable"></el-button>
</div>
</template>
