微信小程序开发地图定位。
微信小程序 刚刚公布没多久,自己学习一下内容,以便以后的开发,想落后别人,这里做了一个简单的小程序示例,大家可以参考下
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。
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,参见百度地图接口文档:http://developer.baidu.com/map/index.PHP?title=webapi/guide/webservice-geocoding
这里用到微信小程序的文档里面有发起的是https请求
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","direction":"南","distance":"60","name":"卓越大厦","point":{"x":114.05777870287507,"y":22.543597255274773},"uid":"c7fb04bd8fb44d68fb0cad85",{"addr":"深圳市福田区","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","uid":"0e082dd9db526730aecb66f9",{"addr":"福华一路南侧","distance":"123","name":"投行大厦","point":{"x":114.05829972007068,"uid":"b3a40a67bedbe7782fb17ea0",{"addr":"深圳福田区国际商会大厦A座","direction":"东北","distance":"77","name":"深圳国际商会大厦A座","point":{"x":114.05750022816707,"y":22.54255414230188},"uid":"108ed554a3f5358229fc4892",{"addr":"福华一路88号","direction":"西","distance":"131","name":"中心商务大厦","point":{"x":114.05899141531315,"y":22.54275442061121},"uid":"cac5fc76d0304d8e2db96d8b",{"addr":"深圳市福田区福华一路88号中心商务大厦首层","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","uid":"c7fb04bd3d531f6bfa0cadef",{"addr":"深圳福田中心区福华一路28号(投资大厦旁)","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","uid":"0523a14106ceb804b23c8142",{"addr":"福华一路208号购物公园B1层","distance":"234","name":"永旺超市(购物公园店)","point":{"x":114.05971904277598,"y":22.542170274720726},"tag":"购物;超市","uid":"9884a864bb2c032af8dc85d1",{"addr":"深圳市福田区深南大道4103号兴业银行大厦17-18层","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","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
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
类型 | 默认值 | 说明 |
---|---|---|
时间选择器:mode = time
类型 | 默认值 | 说明 |
---|---|---|
日期选择器:mode = date
类型 | 默认值 | 说明 |
---|---|---|
注意:开发工具暂时只支持mode = selector。
示例代码:
<view class="section">
<view class="section__title">日期选择器
<picker mode="date" value="{{date}}" start="2015-09-01" end="2017-09-01" bindchange="bindDateChange">
<view class="picker">
当前选择: {{date}}
