底部标签底部标签是一个tabBar。实现比较简单，只需要简单配置一下即可。 app.json
{ "pages":[ "pages/function/function", "pages/pay/pay", "pages/account/account", "pages/index/index", "pages/logs/logs" ], "tabBar":{ "color": "#464a56", "selectedColor": "#6595e9", "backgroundColor": "#FFFFFF", "borderStyle": "white", "list": [{ "pagePath": "pages/function/function", "text": "功能", "iconPath": "images/tab_function_default.png", "selectedIconPath": "images/tab_function_sel.png" },{ "pagePath": "pages/pay/pay", "text": "收款", "iconPath": "images/tab_consume_default.png", "selectedIconPath": "images/tab_consume_sel.png" },{ "pagePath": "pages/account/account", "text": "账户", "iconPath": "images/tab_account_default.png", "selectedIconPath": "images/tab_account_sel.png" }] }, "window":{ "navigationBarBackgroundColor": "#6595e9", "navigationBarTextStyle":"white", "navigationBarTitleText": "V50", "backgroundColor": "#eeeeee", "backgroundTextStyle":"light" }}值得注意的地方，就是 pages 接受一个数组，每一项都是字符串，来指定小程序由哪些页面组成。每一项代表对应页面的【路径+文件名】信息，数组的第一项代表小程序的初始页面。
小程序中新增/减少页面，都需要对 pages 数组进行修改。
文件名不需要写文件后缀，因为框架会自动去寻找路径.json, .js , .wxml, .wxss的四个文件进行整合。
页面标题：
页面标题这个标题如何实现？ 我们翻看一下官方文档。
原来如此！我们只需要把所有页面通用的配置放在 page.json，然后在各个page的 .json文件里面配置每个页面特有的属性即可。因为在上面的 app.json 中已经配置了通用页面的 window属性了，我们只需要在function.json中配置页面标题即可：
{ "navigationBarTitleText": "功能" }轮播图
接下来实现顶部的轮播图。微信提供了一个swiper组件来实现轮播图。
代码也就出来了：function.wxml
function.js//function.jsPage({ data: { indicatorDots: true, autoplay: true, interval: 5000, duration: 1000, imgUrls: [ 'http://img02.tooopen.com/images/20150928/tooopen_sy_143912755726.jpg', 'http://img06.tooopen.com/images/20160818/tooopen_sy_175866434296.jpg', 'http://img06.tooopen.com/images/20160818/tooopen_sy_175833047715.jpg' ], },})
没错，微信小程序的轮播图就是这么简单！在这里可能有的同学要问了：“轮播图的图片用的是url地址，如果我想用本地的图片呢？能不能实现？ ”
这个官方文档没有介绍，但是我们经过测试，是可以实现的。代码如下
imgUrls: [ '../../images/adv_50.png', '../../images/adv_60.png', '../../images/adv_80.png' ],
中间功能模块
中间的8个功能模块，类似Android的GridView效果。本文采取循环的方式来实现：function.wxml
function.jsfunctions: [ { "name": "刷卡消费", "pic_url": '../../images/icon_consume.png' }, { "name": "提现", "pic_url": '../../images/icon_withdrawals.png' }, { "name": "交易记录", "pic_url": '../../images/icon_records.png' }, { "name": "实名认证", "pic_url": '../../images/icon_auth.png' }, { "name": "飞机票", "pic_url": '../../images/icon_airplane.png' }, { "name": "火车票", "pic_url": '../../images/icon_train.png' }, { "name": "手机充值", "pic_url": '../../images/icon_phone_recharge.png' }, { "name": "水电煤", "pic_url": '../../images/icon_water.png' } ]function.wxss/**function.wxss**/.container { height: 650px;}.slide-image{ display: block; height: 280rpx; width:100%}.function_container{ display:flex; flex-wrap: wrap; width:100%;}.function_item{ width:25%; display:flex; flex-direction:column; justify-content:center; align-items:center; font-size:12px; box-sizing:border-box; padding-bottom:10px; padding-top:10px}.function_img{ width:60px; height:60px;}.function_name{ padding-top:10px} {{function.name}}
这里通过width:25% 来实现每行排列四个功能按钮的效果。

下面的布局就比较简单了，直接上完整的代码了：function.wxml
