uniapp H5 实现地图选址功能

这段时间因为项目中使用到地图选址，由于第一次在uniapp中使用地图选址功能，全部都是网上查找相关资料，遇到很多坑，后面自己从新利用map组件写了一个，下面方法列出来，uniapp腾讯地图key申请与部署就不写了，自行百度，仅供参考

方法一

腾讯地图官网地图官网地图选址组件 地图组件 | 腾讯位置服务

优点：使用简单，代码简洁

缺点：定位不准，如果通过uni.getLocation获取定位经纬度传入，组件自带一个箭头点击回到我的位置，我的位置会出现空白

<template><div class="map-warp"><!--#ifdef H5--><web-view :src="url"@message="onMessage"></web-view><!--#endif--></div>
</template><script>export default {data() {return {height: uni.getSystemInfoSync().screenHeight,url:''}},onLoad(option) {if(option){this.url=`=1&type=1&coord=${option.lat},${option.lon}&policy=1&key=HTLBZ-AFZC3-IC435-YTBCH-PJTQQ-RRF7V&referer=myapp`}},onReady() {const self = this//#ifdef H5if (window.isListen) {// 防止多次注册addEventListener事件return}window.addEventListener('message', function (event) {var loc = event.data;if (loc && loc.module == 'locationPicker') {console.log('location', loc);self.getPositon(loc, self)};window.isListen = truewindow.removeEventListener('message', function() {}, true)}, false)//#endif},methods: {onMessage(res) {console.log('app接收网页消息:', res.detail.data[0])this.getPositon(res.detail.data[0], this)},getPositon(res, self) {uni.$emit('onAddressChange', res)setTimeout(function() {uni.navigateBack({delta: 1});}, 500)}},
}
</script><style scoped lang="scss">
</style>

方法二

自己根据uniapp官网map标签实现 map | uni-app官网

这里因为项目时间比较敢，没有实现搜索，后面有时间了补上

因为H5涉及到跨域，所以qqmap-wx-jssdk.min,js需要修改,可直接复制

效果：
