vue 中使用高德地图, 地图选点

标签：mic   1.5   name   pes   tar   inner   elf   marker   near   

功能简述: 网页版高德地图开发,主要支持地图选点(没做导航),搜索选点.(功能类似微信与好友聊天中的选择位置,发送位置,如下图)

第一步:先成为高德地图的开发者(获取高德地图的key);获取key

第二步:引入高德地图js文件

  <!-- 高德地图 -->
    <script src="https://webapi.amap.com/maps?v=1.4.14&key=你申请到高德地图开发者key&plugin=AMap.Driving"></script>
    <!-- UI组件库 -->(这个看情况引入,不要则不引入)
    <script src="//webapi.amap.com/ui/1.0/main.js?v=1.0.11"></script>

第三部:po代码

(1) html部分的:

<div class="map-container" v-if="showMapContainer">
            <div class="map-nav">
                <div class="cancel-btn" @click="cancelChooseAdress"> 取消 </div>
                <div class="map-title"> 位置 </div>
                <div class="confirm-btn" @click="confirmAdress"> 确定 </div>
                <div id="pickerBox">
                    <input id="pickerInput" placeholder="输入关键字选取地点" />
                    <div id="poiInfo"></div>
                </div>
            </div>
            <div id="container" style="width:100%;height:8rem;" class="map" tabindex="0"></div>

            <div class="adress">
                <div style="display:none">
                    <div>
                        <div class='title'>选择模式</div>
                        <input type='radio' name='mode' value='dragMap' checked>拖拽地图模式</input>
                        </br>
                        <input type='radio' name='mode' value='dragMarker'>拖拽Marker模式</input>
                    </div>
                    <div>
                        <button id='start'>开始选点</button>
                        <button id='stop'>关闭选点</button>
                    </div>
                </div>
                <div class="adress-info">
                    <div class='title'>选址结果</div>
                    <div class='c'>
                        <span class="adress-info-label">经纬度:</span>
                        <span id='lnglat' v-model="addressInfo.position"></span>
                    </div>
                    <div class='c'>
                        <span class="adress-info-label">地址:</span>
                        <span id='address'></span>
                    </div>
                    <div class='c'>
                        <span class="adress-info-label">最近的路口:</span>
                        <span id='nearestJunction'></span>
                    </div>
                    <div class='c'>
                        <span class="adress-info-label">最近的路:</span>
                        <span id='nearestRoad'></span>
                    </div>
                    <div class='c'>
                        <span class="adress-info-label">最近的POI:</span>
                        <span id='nearestPOI'></span>
                    </div>
                </div>
            </div>
        </div>

(2) ts部分的(有一些变量没有放,大家自己补充哈.注意:::::declare const AMapUI: any;
declare const AMap: any;这两句在typescript中必须写,不写功能虽然正常,但是会报语法错误 ):

declare const AMapUI: any;
declare const AMap: any;

getLocation() {
            var self = this
            AMapUI.loadUI(['misc/PositionPicker', 'misc/PoiPicker'], function (PositionPicker: any, PoiPicker: any) {

                var poiPicker = new PoiPicker({
                    input: 'pickerInput' //输入框的id
                });

                var map = new AMap.Map('container', {
                    zoom: 15,  //缩放层级
                    center: self.postionArray //[121.596739, 31.194049],//当前地图中心点
                })

                var positionPicker = new PositionPicker({
                    mode: 'dragMap',
                    map: map,
                });

                positionPicker.on('success', function (positionResult: any) {
                    document.getElementById('lnglat')!.innerHTML = positionResult.position;
                    document.getElementById('address')!.innerHTML = positionResult.address;
                    document.getElementById('nearestJunction')!.innerHTML = positionResult.nearestJunction;
                    document.getElementById('nearestRoad')!.innerHTML = positionResult.nearestRoad;
                    document.getElementById('nearestPOI')!.innerHTML = positionResult.nearestPOI;
                    
                    self.addressInfo.address = positionResult.address;
                    self.addressInfo.position = positionResult.position;
                });
                positionPicker.on('fail', function (positionResult: any) {
                    document.getElementById('lnglat')!.innerHTML = ' ';
                    document.getElementById('address')!.innerHTML = ' ';
                    document.getElementById('nearestJunction')!.innerHTML = ' ';
                    document.getElementById('nearestRoad')!.innerHTML = ' ';
                    document.getElementById('nearestPOI')!.innerHTML = ' ';
                    
                    self.addressInfo.address = positionResult.address;
                    self.addressInfo.position = positionResult.position;
                });
                positionPicker.start();
                map.panBy(0, 1);
                
                
                //初始化poiPicker
                poiPickerReady(poiPicker);
                // 搜索框
                function poiPickerReady(poiPicker: any) {
                    (window as any).poiPicker = poiPicker;
                    var marker = new AMap.Marker();
                    var infoWindow = new AMap.InfoWindow({
                        offset: new AMap.Pixel(0, -20)
                    });
                    //选取了某个POI
                    poiPicker.on('poiPicked', function (poiResult: any) {
                        var source = poiResult.source,
                            poi = poiResult.item,
                            info = {
                                source: source,
                                id: poi.id,
                                name: poi.name,
                                location: poi.location.toString(),
                                address: poi.address
                            };
                        infoWindow.setMap(map);
                        marker.setPosition(poi.location);
                        infoWindow.setPosition(poi.location);
                        infoWindow.open(map, marker.getPosition());
                        map.setCenter(marker.getPosition());
                    });
                }
            });
        }

(3)css部分:

.map-container {
        width: 100%;
        overflow: scroll;
        height: 100%;
        position: absolute;
        top: 0;
        left: 0;
        background-color: #fff;
        z-index: 10;
        overflow: hidden;

        .map-nav {
            display: flex;
            justify-content: space-between;
            align-items: center;
            flex-wrap: wrap;
            padding: 0.2rem;
            padding-bottom: 0;
            background-color: #EDEDED;
            height: 2.5rem;

            .map-title {
                font-size: 0.4rem;
                height: 0.7rem;
                font-weight: bold;
            }

            .confirm-btn {
                background-color: #57BE69;
                color: #fff;
                padding: 0.1rem 0.2rem;
                border-radius: 4px;
                font-size: 0.377rem;
            }

            .cancel-btn {
                font-size: 0.377rem;
                padding: 0.1rem 0.2rem;
                border-radius: 4px;
            }
        }
    }

最后在po一张搜索的图

整个复制我也不知道能不能跑起来,有什么问题也随时可以交流.你若是喷我,不好意思,你是小狗.
