任务二工单3:取餐信息界面研发

1.效果图
1、根据设计效果图,完成take-foods.vue的取餐信息页面布局,布局效果应与图2.3.2所示保持一致。特别注意,view的class样式应全部引用自/static/style/app.scss文件,该文件包含了前端团队小组整理的通用样式类。以下是布局代码:
<template>
<view class="container">
<view class="d-flex w-100 h-100 flex-column just-content-center align-items-center">
<image src="/static/images/loading.gif" class="drinks-img"></image>
<view class="tips d-flex flex-column align-items-center font-size-base text-color-assist">
<view>您还没有点单</view>
<view>快去犒劳一下自己吧~</view>
</view>
<button type="primary" class="drink-btn" size="default">去点餐</button>
<view class="font-size-sm text-color-primary">查看历史订单</view>
</view>
</view>
</template>
<script>
</script>
<style lang="scss" scoped>
.drinks-img {
width: 350rpx;
height: 350rpx;
}
.tips {
margin: 60rpx 0 80rpx;
line-height: 48rpx;
}
.drink-btn {
width: 320rpx;
border-radius: 50rem !important;
margin-bottom: 40rpx;
font-size: $font-size-base;
line-height: 3.0;
}
</style>

2、团队成员编写取餐页面逻辑,当用户点击“去点餐”按钮时,页面会切换至点餐配送界面(menu.vue)。以下是相关代码片段。用户可以通过点击来查看历史订单,并通过@tap指令实现交互,从而跳转至历史订单界面。
menu.vue
<template>
<view class="container">
<view class="d-flex w-100 h-100 flex-column just-content-center align-items-center">
<image src="/static/images/loading.gif" class="drinks-img"></image>
<view class="tips d-flex flex-column align-items-center font-size-base text-color-assist">
<view>您还没有点单</view>
<view>快去犒劳一下自己吧~</view>
</view>
<button type="primary" class="drink-btn" size="default" @tap="menu">去点餐</button>
<view class="font-size-sm text-color-primary" @tap="orders">查看历史订单</view>
</view>
</view>
</template>
<script>
export default {
data() {
return {
};
},
methods: {
menu() {
uni.switchTab({
url: '/pages/menu/menu'//切换点餐界面
})
}
}
}
</script>
<style lang="scss" scoped>
.drinks-img {
width: 350rpx;
height: 350rpx;
}
.tips {
margin: 60rpx 0 80rpx;
line-height: 48rpx;
}
.drink-btn {
width: 320rpx;
border-radius: 50rem !important;
margin-bottom: 40rpx;
font-size: $font-size-base;
line-height: 3.0;
}
</style>
在跳转至历史订单界面之前,系统需先判断用户是否已经登录。若检测到用户未登录状态,系统将引导用户至登录界面,并在登录成功后将用户状态标记为已登录。若用户已登录,则直接跳转至历史订单界面。
在“pages”目录下创建两个新文件:一个是登录界面(login.vue),另一个是历史订单界面(orders.vue)。随后,在pages.json文件中对这两个界面的样式进行相应的配置。
orders.vue
<template>
<view>
历史订单
</view>
</template>
<script>
export default {
data() {
return { };
}
}
</script>
<style lang="scss">
</style>
pages.json中样式设定
{
"path" : "pages/login/login",
"style" :
{
"navigationBarTitleText": "登录",
"navigationBarTextStyle": "black",
"navigationBarBackgroundColor": "#ffffff"
}
},
{
"path" : "pages/orders/orders",
"style" :
{
"navigationBarTitleText": "历史订单",
"navigationBarTextStyle": "black",
"navigationBarBackgroundColor": "#ffffff"
}
}
团队成员完成登录页面(login.vue)的布局设计,其效果展示请参见图2.3.4。

★3、为了有效管理本项目的状态数据,团队小组成员引入了/store/index.js文件,如图2.3.3所示。在index.js中,不仅存储了用户登录信息、商户详情、购物车内容、取餐方式、地址信息等数据,如图2.3.4所示,还集成了共享方法,例如清空购物车中的商品、配置订单信息、更新用户信息等。此外,在main.js文件中,定义了所有Vue实例共享的$store方法,具体代码如下:
import Vue from 'vue'
import App from './App'
import api from './api'
import store from './store'
Vue.config.productionTip = false
App.mpType = 'app'
Vue.prototype.$api = api
Vue.prototype.$store = store
const app = new Vue({
...App
})
app.$mount()

2.3.5 引入store下index.js状态文件.png

2.3.6 引入store中状态对象.png
在实现登录页面的交互时,点击事件会触发store/index.js文件中的SET_MEMBER动作,从而将用户信息存储到state.member状态中。当用户点击图2.3.2以查看历史订单时,可以利用this.$store.getters.isLogin方法来进行逻辑判断:未登录状态将引导用户至登录页面,而登录状态则会重定向至历史订单页面。以下是本工单登录页面的代码实现和点餐页面完整代码:
take-foods.vue

},
methods: {

uni.switchTab({

},
orders() {
//如果未登录,如何判断是否登录
if(!this.$store.getters.isLogin) {
uni.navigateTo({url: '/pages/login/login'})
return
}
//如果已登录
uni.navigateTo({

})
},
}
