# 三期复盘总结
## el-checkbox
遇到好几次不同需求,处理的方式都不同. 如果采用 v-for 循环的话 可以直接免对数据项做处理,否则就要自己处理 checkbox 的数据.
```js
// 1. 自己操作
网游 sdk
单机 sdk
clickItem(e) {
// 获取到 e ,如果有 arr 里面有 e 则去掉
let arr = this.checkList;
const arr2 = ['supportNetGame', 'supportSingleGame'];
if (arr.includes(e)) {
arr = arr2.filter(i => i !== e);
this.checkList = [...arr]
} else {
// 不存在
this.checkList.push(e)
}
// 2. 无需操作
{{item.label}}
handleCheckedCitiesChange(e) {
console.log('e: ', e);
},
```
## 时间戳处理
默认情况下得到的是时间戳, 我们可以将其 xxxx-xx-xx,在统一进行比较.
```js
formatTime(val) {
const date = new Date(val * 1000);
const Y = date.getFullYear();
const M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1);
const D = date.getDate() + ' ';
return Y + M + D
}
```
## 表单验证
针对层级嵌套比较深 Form 表单采用单个 input 框处理,在提交的时候可以在进行一次验证
```js
@keyup.native="validateEventHandle(dynamicProportion)"
validateEventHandle(val) {
console.log('val: ', val);
if (val.proportion > 50) {
this.$message.error('返回比例不能大于 50');
val.proportion = '';
}
if (val.proportion < 0) {
this.$message.error('返回比例不能小于 0');
val.proportion = '';
}
},
if (data[i].payMax < data[i].payMin) {
this.$message.error('最大和最小充值金额设置比例错误');
return
}
```
## el-radio-group
label 放入的数字 对应为 string 类型, :label 则为 number 类型.在做校验的时候可能会报错.所以我们要转换一下
```js
按接入方式
自定义
```
## form 表单 时间戳,做空判断
```js
const startTime = Number(createTime[0]) / 1000 || '';
const endTime = Number(createTime[1]) / 1000 || '';
```
