项目搭建
参考上一节内容
开发试题分类页面
pages 目录下新建 home 目录,并添加 4 个文件,如图所示:
其中:
home.js
// pages/home/home.js
Page({data: {},
onLoad: function (options) { },
toTestPage: function(e){let testId = e.currentTarget.dataset['testid'];
wx.navigateTo({url: '../test/test?testId='+testId})
}
})
home.wxml
<!--pages/home/home.wxml-->
<view class="page">
<view class="page-title"> 请选择试题:</view>
<view class="flex-box">
<view class="flex-item"><view class="item bc_green" bindtap="toTestPage" data-testId="18">IT 知识 </view></view>
<view class="flex-item"><view class="item bc_red" bindtap="toTestPage" data-testId="15"> 游戏知识 </view></view>
<view class="flex-item"><view class="item bc_yellow" bindtap="toTestPage" data-testId="21"> 体育知识 </view></view>
<view class="flex-item"><view class="item bc_blue" bindtap="toTestPage" data-testId="27"> 动物知识 </view></view>
<view class="flex-item item-last"><view class="item bc_green" bindtap="toTestPage" data-testId="0"> 综合知识 </view></view>
</view>
</view>
home.json
{
"navigationBarTitleText": "试题分类",
"usingComponents": {}}
home.wxss
/* pages/home/home.wxss */
.page-title {
padding-top: 20rpx;
padding-left: 40rpx;
font-size: 16px;
}
.flex-box {
display: flex;
align-items:center;
flex-wrap: wrap;
justify-content: space-between;
padding: 20rpx;
box-sizing:border-box;
}
.flex-item {
width: 50%;
height: 200rpx;
padding: 20rpx;
box-sizing:border-box;
}
.item {
width:100%;
height:100%;
border-radius:8rpx;
display: flex;
align-items:center;
justify-content: center;
color: #fff;
}
.item-last {flex: 1;}
修改 app.json,注意:pages/home/home 一定要放到 pages 数组的最前,以成为首页。
{
"pages": [
"pages/home/home",
"pages/index/index",
"pages/logs/logs",
],
"window": {
"backgroundTextStyle": "light",
"navigationBarBackgroundColor": "#fff",
"navigationBarTitleText": "WeChat",
"navigationBarTextStyle": "black"
},
"style": "v2",
"sitemapLocation": "sitemap.json"
}
修改 app.wxss,定义全局样式
/**app.wxss**/
.container {
height: 100%;
display: flex;
flex-direction: column;
align-items: center;
justify-content: space-between;
padding: 200rpx 0;
box-sizing: border-box;
}
.bc_green{background-color: #09BB07;}
.bc_red{background-color: #F76260;}
.bc_blue{background-color: #10AEFF;}
.bc_yellow{background-color: #FFBE00;}
.bc_gray{background-color: #C9C9C9;}
运行结果
添加试题页
pages 目录下新建 test 目录,并添加 4 个文件,如图所示:
修改 test.js
// pages/test/test.js
Page({
/**
* 页面的初始数据
*/
data: {test_id:0},
/**
* 生命周期函数 -- 监听页面加载
*/
onLoad: function (options) {this.setData({test_id:options.testId})
},
修改 test.wxml
<!--pages/test/test.wxml-->
<text> 我是 {{test_id}}</text>
运行结果
在试题分类页点击某一分类,跳转到试题页,试题页显示分类 id
