uniapp+vant weapp实现课程表小程序_课程表功能的实现
2021/6/1 12:21:55
本文主要是介绍uniapp+vant weapp实现课程表小程序_课程表功能的实现，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
课程表功能的实现
- 思路
- 1.节数与天数和grid内单选框索引的转换
- 2.单选框样式的魔改
- 温馨提示:尽量用原生
- 源码
思路
课程表的实现,我想了很久,在没有现成组件库的情况下实现,我主要是用了vant weapp的宫格和单选框来实现,主要的难点有以下两个方面:
1.节数与天数和grid内单选框索引的转换
返回值给我一个包含课程节数和天数的对象数组,我把它转换成一个包含unit(5节课*7天的对应的数字来定位)的对象数组
2.单选框样式的魔改
单选框直接使用radio的插槽来贴图来适应样式需求
<van-radio-group :value="unit" @change="addClass">
<van-grid :border="false" :column-num="7" :clickable="true">
<van-grid-item v-for="value in 35" :key="value" use-slot custom-class="editCourse">
<van-button type="primary" color="#006600" v-show="map[value]!==-1?true:false"
@click="editCourse(value)"
custom-style="padding-left:5rpx;line-height:35rpx;padding-right:5rpx;padding-top:5rpx;height:203rpx;margin: 0 auto;width:90rpx;border-radius: 10rpx;font-size:25rpx!important;font-weight:bold">
<div>{{InfoMap[value].courseName}}</div>
</van-button>
<van-radio use-icon-slot :value="unit" :name="value" v-show="map[value]!==-1?false:true">
<image style="margin-top:10rpx;height:190rpx;width:90rpx;" slot="icon"
:src="unit===value?icon.choosed:icon.unChoosed" />
</van-radio>
</van-grid-item>
</van-grid>
</van-radio-group>
这样就看不出来是单选框了
温馨提示:尽量用原生
其他主要是布局和样式,没啥好说的.吐槽一句,vant组件库的插槽不是真的放在组件里面,而是悬浮在它上面,有时候会出现错位的情况.
所以能用原生尽量用原生,组件样式带原生样式,样式穿透和!important都不起作用,不太好把握(主要是我太菜了,css好难)
