vue2.x使用百度地图

在12月份之前在vue项目中使用百度地图我都是在index.html直接应用如下代码

<script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=你的秘钥"></script>

然后直接在页面直接初始化地图即可，注意地图一定要设置宽和高。

现在我被同事硬性拧过来使用vue baidu map。中文文档地址https://dafrok.github.io/vue-baidu-map/#/zh/index。

此插件将需要使用的控件、覆盖物都封装成组件。要使用的话需要先引入并申明。如下

import { BaiduMap, BmLabel, BmGeolocation, BmOverlay, BmInfoWindow } from 'vue-baidu-map'

给一个使用较完整的例子

    <baidu-map @moveend="moveendMap"  @ready="readyMap" class="bm-view" v-bind:100%', height: winHeight + 'px' }" :center="center" ak="tRcad54fc5HjGw1mZ64lttoT" :zoom="zoom">
      <bm-info-window  :position="windowLabelPoint"  :show="infoWindow.show" @close="infoWindowClose" @open="infoWindowOpen" >
        <a class="header-label" :href="shopBaseinfo.url">
          <div class="shopname" v-text="shopBaseinfo.serviceProviderName"></div>
          <span>详情»</span>
        </a>
        <div class="base-info" >
          <span v-text="'案例个数: '+shopBaseinfo.caseNum+'个'"></span>
          <span v-text="'案例个数: '+shopBaseinfo.shopDesignerNum+'个'"></span>
        </div>
      </bm-info-window>
      <bm-label
        v-for="(item,index) in decShopPointerList"
        @click="getShopInfo(item.id,index,item.longitude,item.latitude)"
        :key="item.id"
        :content="item.serviceProviderName"
        :position="{lng: item.longitude, lat: item.latitude}"
        :label
        :title="item.serviceProviderName"/>
    </baidu-map>

在vue baidu map中依然遵守数据改变视图更新

使用vue baidu map时我想将地址解析出来并在地图上描点，在vue baidu map的官方文档上没看到。可以在百度地图官方文档中找，可使用Geocoder()构造函数，创建一个地址解析器的实例。用法如下：

    var myGeo = new BMap.Geocoder();
    // 将地址解析结果显示在地图上,并调整地图视野
    myGeo.getPoint("北京市海淀区上地10街", function(point){
        if (point) {
            map.centerAndZoom(point, 16);
            map.addOverlay(new BMap.Marker(point));
        }else{
            alert("您选择地址没有解析到结果!");
        }
    }, "北京市");

获取当前位置经纬度

let geolocation = new BMap.Geolocation();
geolocation.getCurrentPosition(function (r) {
    if (this.getStatus() == BMAP_STATUS_SUCCESS) {
        let point = r.point.lng + ',' + r.point.lat;
        
    }else {
        console.log('failed' + this.getStatus());
    }
}, { enableHighAccuracy: true })
