　　现在的年轻人在陌生的地方更多的使用就是一些地图来帮助自己找到想要去的地方，那么微信小程序地图定位功能要是能够做得更好的话，就更加符合年轻人的要求了，那么接下来就来为大家解答微信小程序地图定位功能如何制作?

　　要求要完成的功能：

　　1)要完成的要点是城市定位。

　　2)就是切换城市。

　　下面就是相关的制作步骤，大家想学习的都可以过来瞧一瞧。

　　1、首页我们先参照微信小程序开放的官方文档找到：

　　2、在这里我们可以找到“当前位置经纬度”。

　　3、//将经纬度转换成城市名和街道地址，参见百度地图接口文档：

developer.baidu/map/index.php?title=webapi/guide/webservice-geocoding

　　4、这里用到微信小程序的文档里面有发起的是s请求。

　　5)这里面有案例我就不多讲解，上面的代码打印出来的数据是：

　　renderReverse&&renderReverse(

　　{"status":0,

　　"result":

　　{"location":{"lng":114.05786799999997,"lat":22.543098999645019},

　　"formatted_address":"广东省深圳市福田区福华一路138-5",

　　"business":"购物公园,新洲,香蜜湖",

　　"addressComponent":{"country":"中国","country_code":0,"province":"广东省","city":"深圳市","district":"福田区","adcode":"440304","street":"福华一路","street_number":"138-5","direction":"附近","distance":"18"},"pois":[{"addr":"深圳市福田区福华一路138号","cp":" ","direction":"北","distance":"51","name":"深圳国际商会大厦","poiType":"房地产","point":{"x":114.05776971981998,"y":22.54267931627966},"tag":"房地产;写字楼","tel":"","uid":"9ed8fd9034cebefaeb12e42c","zip":""},{"addr":"福华一路98号","cp":" ","direction":"南","distance":"60","name":"卓越大厦","poiType":"房地产","point":{"x":114.05777870287507,"y":22.543597255274773},"tag":"房地产;写字楼","tel":"","uid":"c7fb04bd8fb44d68fb0cad85","zip":""},{"addr":"深圳市福田区","cp":" ","direction":"西北","distance":"236","name":"购物公园","poiType":"购物","point":{"x":114.05972802583108,"y":22.54214523984097},"tag":"购物;购物中心","tel":"","uid":"0e082dd9db526730aecb66f9","zip":""},{"addr":"福华一路南侧","cp":" ","direction":"西北","distance":"123","name":"投行大厦","poiType":"房地产","point":{"x":114.05829972007068,"y":22.54214523984097},"tag":"房地产;写字楼","tel":"","uid":"b3a40a67bedbe7782fb17ea0","zip":""},{"addr":"深圳福田区国际商会大厦A座","cp":" ","direction":"东北","distance":"77","name":"深圳国际商会大厦A座","poiType":"房地产","point":{"x":114.05750022816707,"y":22.54255414230188},"tag":"房地产;写字楼","tel":"","uid":"108ed554a3f5358229fc4892","zip":""},{"addr":"福华一路88号","cp":" ","direction":"西","distance":"131","name":"中心商务大厦","poiType":"房地产","point":{"x":114.05899141531315,"y":22.54275442061121},"tag":"房地产;写字楼","tel":"","uid":"cac5fc76d0304d8e2db96d8b","zip":""},{"addr":"深圳市福田区福华一路88号中心商务大厦首层","cp":" ","direction":"西","distance":"134","name":"招商银行(中央商务支行)","poiType":"金融","point":{"x":114.05900039836824,"y":22.542704351061439},"tag":"金融;银行","tel":"","uid":"c7fb04bd3d531f6bfa0cadef","zip":""},{"addr":"深圳福田中心区福华一路28号(投资大厦旁)","cp":" ","direction":"西","distance":"229","name":"深圳马哥孛罗好日子酒店","poiType":"酒店","point":{"x":114.05991666998811,"y":22.54288793932078},"tag":"酒店;星级酒店","tel":"","uid":"0523a14106ceb804b23c8142","zip":""},{"addr":"福华一路208号购物公园B1层","cp":" ","direction":"西北","distance":"234","name":"永旺超市(购物公园店)","poiType":"购物","point":{"x":114.05971904277598,"y":22.542170274720726},"tag":"购物;超市","tel":"","uid":"9884a864bb2c032af8dc85d1","zip":""},{"addr":"深圳市福田区深南大道4103号兴业银行大厦17-18层","cp":" ","direction":"西南","distance":"158","name":"深圳市公证处(一号路)","poiType":"政府机构","point":{"x":114.05857819477869,"y":22.54424815372944},"tag":"政府机构;公检法机构","tel":"","uid":"765bf8daf4efd08cb45f1ec0","zip":""}],"poiRegions":[],"sematic_description":"深圳国际商会大厦北51米","cityCode":340}})

　　你找到city传进去就可以了，

　　第二步切换城市：

　　在次找到我们的微信小程序的开发文档里面有

　　picker

　　滚动选择器，现支持三种选择器，通过mode来区分，分别是普通选择器，时间选择器，日期选择器，默认是普通选择器。

　　普通选择器：mode = selector

　　6、时间选择器：mode = time

　　7、日期选择器：mode = date

8、注意：开发工具暂时只支持mode = selector。

　　示例代码：
