Vue学习笔记-高德地图组件

2019-03-07  本文已影响237人  赵客缦胡缨v吴钩霜雪明

公司之前一直使用的是百度地图组件,最近运营人员一直反映一个问题:有一些地区在百度地图上搜不到,地址搜索没有响应。我以为是地图API版本不对,更新了版本,这个问题还是存在。于是我就考虑换一个地图组件也解决这个问题,于是高德就成了我的第一选择。

准备工作:

高德开放平台,注册成为开发者。

申请Key,我申请的是Web端(JS API),不同的API效果可能不一样。

实现方式:

一:引入 高德,web-sdk (两种方式)

1:在index.html 中引入

<script type="text/javascript" src="http://webapi.amap.com/maps?v=1.4.6&key=你申请的高德appKey&plugin=AMap.Walking"></script>

2:安装vue-amap

Vue-amap基于Vue2.0的高德地图的地图组件。

 cnpm install vue-amap --save
二.在webpack.base.conf.js加入
externals: {
    'AMap': 'AMap',
}
三.实例

1.方式一

<template>
    <div class="hello">
    <el-input id="keyword" name="input" placeholder="请输入您要定位的位置" v-model="input"></el-input>
    <div style="height:500px" id="container" tabindex="0"></div>
    </div>
</template>

<script>
    import AMap from 'AMap'

    export default {
        name: 'HelloWorld',
        data() {
            return {
                msg: 'hello',
                input: '',
            }
        },
        mounted() {
            this.init();
        },
        methods: {
            init: function () {
                let that = this;
                let map = new AMap.Map('container', {
                    center: [116.397428, 39.90923],
                    resizeEnable: true,
                    zoom: 10,
                    lang: 'ch',
                    keyboardEnable: true
                });
                AMap.plugin('AMap.Geolocation', function () {
                    var geolocation = new AMap.Geolocation({
                        // 是否使用高精度定位,默认:true
                        enableHighAccuracy: true,
                        // 设置定位超时时间,默认:无穷大
                        timeout: 10000,
                        // 定位按钮的停靠位置的偏移量,默认:Pixel(10, 20)
                        buttonOffset: new AMap.Pixel(10, 20),
                        // 定位成功后调整地图视野范围使定位位置及精度范围视野内可见,默认:false
                        zoomToAccuracy: true,
                        // 定位按钮的排放位置, RB表示右下
                        buttonPosition: 'RB'
                    })
                    geolocation.getCurrentPosition()

                    AMap.event.addListener(geolocation, 'complete', (e) => {
                        console.log(e) // 定位成功之后做的事
                        // 定位成功之后再定位处添加一个marker
                        var marker = new AMap.Marker({
                            position: e.position, // (e.position)--->定位点的点坐标, position ---> marker的定位点坐标,也就是marker最终显示在那个点上,
                            icon: '', // marker的图标,可以自定义,不写默认使用高德自带的
                            map: map,  // map ---> 要显示该marker的地图对象
                        });
                    });
                    AMap.event.addListener(geolocation, 'error', (e) => {
                        console.log(e) // 定位失败做的事
                    })
                })
                AMap.plugin(['AMap.Autocomplete', 'AMap.PlaceSearch'], function () {
                    var autoOptions = {
                        city: "北京", //城市,默认全国
                        input: 'keyword',//使用联想输入的input的id
                    };
                    var autocomplete = new AMap.Autocomplete(autoOptions);
                    var placeSearch = new AMap.PlaceSearch({
                        city: '北京',
                        map: map
                    })
                    AMap.event.addListener(autocomplete, "select", function (e) {
                        //TODO 针对选中的poi实现自己的功能
                        placeSearch.setCity(e.poi.adcode);
                        placeSearch.search(e.poi.name)
                    });
                });
                AMap.plugin(['AMap.ToolBar', 'AMap.Scale'], function () {
                    map.addControl(new AMap.ToolBar())
                    map.addControl(new AMap.Scale())
                })
            },
        }
    }
</script>

2.方式二

封装一个mapDrag的组件

                </el-input>
            </div>
            <div id="js-result" v-show="searchKey" class="result"></div>

        margin-bottom: 10px;
        color: #333;
    }

    .m-part .mapbox {
        width: 600px;
        height: 400px;
        margin-bottom: 20px;
        float: left;
    }
</style>

效果如图:
