本文通过一个实际例子,来讲解如何进行微信小程序的页面搭建。首先看一下本文要实现的页面效果:

开发工具下载
微信官方有开发者工具,集成了开发调试、代码编辑及程序发布等功能。
微信小程序架构

这个就是程序的基本架构。最关键也是必不可少的,是 app.js、app.json、app.wxss 这三个。其中,.js后缀的是脚本文件,.json后缀的文件是配置文件,.wxss后缀的是样式表文件。
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
| 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | | 11 | | 12 | | 13 | | 14 | | 15 | | 16 | | 17 | | 18 | | 19 | | 20 | | 21 | | 22 | | 23 | | 24 | | 25 | | 26 | | 27 | | 28 | | 29 | | 30 | | 31 | | 32 | | 33 | | 34 | | 35 | | 36 | | 37 |
| | {
| | "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
这个标题如何实现? 我们翻看一下官方文档。
看到这里,你应该就知道了,需要在指定页面的json文件中进行页面配置。继续查看官方的文档

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
| 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | | 11 | | 12 | | 13 | | 14 | | 15 | | 16 | | 17 | | 18 | | 19 | | 20 | | 21 | | 22 |
| | <swiper indicator-dots="{{indicatorDots}}"
| | autoplay="{{autoplay}}" interval="{{interval}}" duration="{{duration}}">
| | <block wx:for="{{imgUrls}}">
| | <swiper-item>
| | <image src="{{item}}" class="slide-image" />
| | </swiper-item>
| | </block></swiper>function.js
| |
| | //function.js
| | Page({
| | 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,兔子哥经过测试,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
| 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | | 11 | | 12 | | 13 | | 14 | | 15 | | 16 | | 17 | | 18 | | 19 | | 20 | | 21 | | 22 | | 23 | | 24 | | 25 | | 26 | | 27 | | 28 | | 29 | | 30 | | 31 | | 32 | | 33 | | 34 | | 35 | | 36 | | 37 | | 38 | | 39 | | 40 | | 41 | | 42 | | 43 | | 44 | | 45 | | 46 | | 47 | | 48 | | 49 | | 50 | | 51 | | 52 | | 53 | | 54 | | 55 | | 56 | | 57 | | 58 | | 59 | | 60 | | 61 | | 62 | | 63 | | 64 | | 65 | | 66 | | 67 | | 68 | | 69 | | 70 | | 71 | | 72 | | 73 | | 74 | | 75 |
| | <view class='function_container'>
| | <view class='function_item' wx:for="{{functions}}" wx:for-index="idx" wx:for-item="function">
| | <image class='function_img' src='{{function.pic_url}}'/>
| | <view class='function_name'>{{function.name}}</view>
| | </view>
| | </view>function.js
| |
| | functions: [
| | {
| | "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
| | } |
|
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
| 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | | 11 | | 12 | | 13 | | 14 | | 15 | | 16 | | 17 | | 18 | | 19 | | 20 | | 21 | | 22 | | 23 | | 24 | | 25 | | 26 | | 27 | | 28 | | 29 | | 30 | | 31 | | 32 | | 33 | | 34 | | 35 | | 36 | | 37 | | 38 | | 39 | | 40 | | 41 | | 42 | | 43 | | 44 | | 45 | | 46 | | 47 | | 48 | | 49 | | 50 | | 51 | | 52 | | 53 | | 54 | | 55 | | 56 | | 57 | | 58 | | 59 | | 60 | | 61 | | 62 | | 63 | | 64 | | 65 | | 66 | | 67 | | 68 | | 69 | | 70 | | 71 | | 72 | | 73 | | 74 | | 75 | | 76 | | 77 | | 78 | | 79 | | 80 | | 81 | | 82 | | 83 | | 84 | | 85 | | 86 | | 87 | | 88 | | 89 | | 90 | | 91 | | 92 | | 93 | | 94 | | 95 | | 96 | | 97 | | 98 | | 99 | | 100 | | 101 | | 102 | | 103 | | 104 | | 105 | | 106 | | 107 | | 108 | | 109 | | 110 | | 111 | | 112 | | 113 | | 114 | | 115 | | 116 | | 117 | | 118 | | 119 | | 120 | | 121 | | 122 | | 123 | | 124 | | 125 | | 126 | | 127 | | 128 | | 129 | | 130 | | 131 | | 132 | | 133 | | 134 | | 135 | | 136 | | 137 | | 138 | | 139 | | 140 | | 141 | | 142 | | 143 | | 144 | | 145 | | 146 | | 147 | | 148 | | 149 | | 150 | | 151 | | 152 | | 153 | | 154 | | 155 | | 156 | | 157 | | 158 | | 159 | | 160 | | 161 | | 162 | | 163 | | 164 | | 165 | | 166 | | 167 | | 168 |
