　　随着微信小程序的热潮来袭，各种小应用层出不穷，而人们在外总是需要地图查询定位的，那有人问微信小程序开发地图定位是怎样操作的？下面是小编整理的相关内容。

　　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。

　　首页我们先参照微信小程序开放的官方文档找到：

　　在这里我们可以找到"当前位置经纬度"

　　将经纬度转换成城市名和街道地址

　　这里用到微信小程序的文档里面有发起的是s请求

　　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

　　时间选择器：mode = time

　　日期选择器：mode = date

　　注意：开发工具暂时只支持mode = selector。

　　示例代码：
