Question

我正在使用VueJS和Leaflet来显示具有特殊本地化的地图。我已经按照文档中的说明在index.html上添加了css传单。

link rel =“ stylesheet” href =“ https://unpkg.com/leaflet@1.2.0/dist/leaflet.css”>

但是我只是地图的一部分。我必须更改屏幕的大小，以使所有地图都带有标记。

这是我实现地图（iMap.vue）的地点

<template>
  <div id="professionnel">
    <b-row>
     <b-tabs>
        <b-tab title="A" >
            <div>
                <b-col class="col-12">
                    <div>Où nous joindre</div>
                </b-col>
            </div>
        </b-tab>
       <b-tab title="B">
            <div class="tab-content-active" >
                <b-col class="col-6">
                    <div>heure</div>
                </b-col>
                <b-col class="col-6 data_map">
                    <iMap1></iMap>
                </b-col>
            </div>
        </b-tab>
      </tabs>
    </b-row>
  </div>
</template>

<script>
import iMap1 from './iMap1'

export default {
  name: 'professionnel',
  components: {
    iMap1
  },
  data() {
    return {}
  }
</script>

这是地图（iMap.vue）的目标

    <template>
        <div id="imap1" class="map" >
        </div>
    </template>

    <script>

    import leaflet from 'leaflet'

    export default {
      name: 'imap1',
      components: {
        leaflet
      },
      data() {
        return {
            professionnel: {},
            map1: null,
            tileLayer: null,
        }
      },
        methods: {
        initMap() {
            this.map1 = L.map('imap1').setView([47.413220, -1.219482], 12)
            this.tileLayer = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
                      //'https://cartodb-basemaps-{s}.global.ssl.fastly.net/rastertiles/voyager/{z}/{x}/{y}.png',
            {
                maxZoom: 18,
                center: [47.413220, -1.219482],
                attribution: '&copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a>, &copy; <a href="https://carto.com/attribution">CARTO</a>',
            }).addTo(this.map1)

 L.marker([47.413220, -1.219482]).addTo(this.map1).bindPopup('name')
                        .openPopup()

 this.map1.invalidateSize()

  })
 },
},
created () {
 this.initMap()
}

}
</script>

使用mounted生命周期挂钩而不是created。

created通常用于预订一些数据/启动某些异步过程，而mounted则是在组件的DOM准备就绪时（但不一定已插入IIRC页中）。

<b-tabs> >

然后，如Data-toggle tab does not download Leaflet map中所述，您必须使用invalidateSize 之后，然后打开包含“地图”容器的标签页，即，您必须监听一个表示您的用户已经打开了标签页。

对于Bootstrap-Vue，您有invalidateSize的{{3}}事件，但是仅在用户单击选项卡时才发出信号。但是后者仍然没有打开。因此，在调用Vue.use(bootstrapVue); Vue.component('imap', { template: '#imap', methods: { resizeMap() { if (this.map1) { this.map1.invalidateSize(); // Workaround to re-open popups at their correct position. this.map1.eachLayer((layer) => { if (layer instanceof L.Marker) { layer.openPopup(); } }); } }, initMap() { this.map1 = L.map('imap1').setView([47.413220, -1.219482], 12) this.tileLayer = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', { maxZoom: 18, center: [47.413220, -1.219482], attribution: '© <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a>', }).addTo(this.map1) L.marker([47.413220, -1.219482]).addTo(this.map1).bindPopup('name') .openPopup() // Opening the popup while the map is incorrectly sized seems to place it at an incorrect position. }, }, mounted() { this.initMap() }, }); new Vue({ el: '#app', methods: { checkMap(tab_index) { if (tab_index === 1) { // Unfortunately the "input" event occurs when user clicks // on the tab, but the latter is still not opened yet. // Therefore we have to wait a short delay to allow the // the tab to appear and the #imap1 element to have its final size. setTimeout(() => { this.$refs.mapComponent.resizeMap(); }, 0); // 0ms seems enough to execute resize after tab opens. } } }, });之前必须给它一个短暂的延迟（通常是"input"）：

var xmlDoc = new XmlDocument();
xmlDoc.Load(@"c:\contour.xml");

在调整屏幕大小之前，无法在带有VueJ和传单的DIV上显示所有地图
