2.登录功能前端实现
2.1在HBuilderX中创建uni-app类型的项目，选择默认模板即可然后建目录结构，如图所示：
- commons目录放置一些全局配置函数
- components目录放置封装的组件
- pages目录放置页面文件
- static目录放置图片资源
-
style目录放置全局样式文件

2.2 pages目录的各个子目录里分别放相应的vue文件

2.3 tab图片
default.png
nav1.png
nav1-a.png
nav2.png
nav2-a.png
nav3.png
nav3-a.png
2.4配置pages.json文件如下：
{
"pages": [
//pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages
{
"path": "pages/index/index",
"style": {
"navigationBarTitleText": "文章",
//允许下拉刷新
"enablePullDownRefresh": true
}
},
{
"path": "pages/message/message",
"style": {
"navigationBarTitleText": "消息"
}
},
{
"path": "pages/my/my",
"style": {
"navigationBarTitleText": "我的"
}
},
{
"path": "pages/signin/signin",
"style": {}
},
{
"path": "pages/write/write",
"style": {}
},
{
"path": "pages/info/info",
"style": {}
},
{
"path": "pages/setting/setting",
"style": {}
}
],
"globalStyle": {
"navigationBarTextStyle": "black",
// "navigationBarTitleText" : "简阅",
"navigationBarBackgroundColor": "#F8F8F8",
"backgroundColor": "#F8F8F8"
},
"tabBar": {
"color": "#707070",
"selectedColor": "#DE533A",
"list": [{
"pagePath": "pages/index/index",
"text": "文章",
"iconPath": "static/nav1.png",
"selectedIconPath": "static/nav1-a.png"
},
{
"pagePath": "pages/message/message",
"text": "消息",
"iconPath": "static/nav2.png",
"selectedIconPath": "static/nav2-a.png"
},
{
"pagePath": "pages/my/my",
"text": "我的",
"iconPath": "static/nav3.png",
"selectedIconPath": "static/nav3-a.png"
}
]
}
}
2.5style目录新建style.css全局样式表
* {
font-size: 14pt;
}
.container {
width: 95%;
margin: 0 auto;
}
.avatar {
width: 60px;
height: 60px;
border-radius: 50%;
}
.list {
display: flex;
flex-direction: column;
}
.list-item {
width: 100%;
height: 50px;
background-color: #fff;
border-bottom: 1px solid #eee;
display: flex;
align-items: center;
}
.green-btn {
background-color: rgb(26, 173, 25);
color: #fff;
}
2.6App.vue文件中引入全局样式表
<style>
@import 'style/style.css';
</style>
2.7 my.vue
