  • vue项目中使用百度地图的方法

    1.在百度地图申请密钥:

     http://lbsyun.baidu.com/  将

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

    中的 密钥替换成你申请的,在 vue项目的index.html引用。

    2. 在build 文件下下的 webpack.base.conf.js贴入代码

    externals: {
      "BMap": "BMap"
     },

    3. map.vue代码(demo可以直接使用,demo使用了vue-clipboard2插件,请自行安装)

    <template>
      <div>
        <el-row >
         <el-col :offset="2" :span="8">
           <el-input :id="suggestId" v-model="address_detail" :clearable='clearable' placeholder="请输入店铺地址,获取店铺坐标" >
          </el-input>
        </el-col>
        <el-col :span="2">
          <el-button id="position" @click="search" type="primary">定位</el-button>
        </el-col>
        <el-col :span="12" >
         <el-tag type="success" v-clipboard:copy="userlocation.lng" v-clipboard:success="onCopy" v-clipboard:error="onError" >经度 {{userlocation.lng}}</el-tag>
         <el-tag type="success" v-clipboard:copy="userlocation.lat" v-clipboard:success="onCopy" v-clipboard:error="onError">纬度 {{userlocation.lat}}</el-tag>
