|
|
> 前端常量 枚举工具
|
|
|
|
## **一、安装及初始化方法**
|
|
|
|
```
|
|
1. npm install vue-enum --save
|
|
2. 按以下格式定义您的枚举对象
|
|
|
|
let enumInfo = {
|
|
SOURCE_IN_TYPE: {
|
|
PURCHASE_IN: {
|
|
value: 1,
|
|
desc: '采购入库'
|
|
},
|
|
REFUND_IN: {
|
|
value: 2,
|
|
desc: '退货入库'
|
|
},
|
|
CHECK_IN: {
|
|
value: 3,
|
|
desc: '盘点入库'
|
|
},
|
|
CONFIRM_IN: {
|
|
value: 4,
|
|
desc: '取消订单入库'
|
|
}
|
|
}
|
|
}
|
|
3. import Enum from 'vue-enum'
|
|
4. Vue.use(Enum,{enumInfo})
|
|
|
|
```
|
|
|
|
|
|
|
|
## **二、使用方法**
|
|
|
|
目前插件提供三个方法
|
|
|
|
可在全局使用this.$enum.getDescByValue() 、this.$enum.getValueDescList() 、getValueDesc() 调用
|
|
|
|
|
|
根据枚举值获取描述
|
|
示例：
|
|
|
|
>在表格渲染时经常遇到需要将状态转换成描述的情况,此时可以使用
|
|
|
|
```
|
|
params.row.sourceType=1
|
|
this.$enum.getDescByValue('SOURCE_IN_TYPE', params.row.sourceType)) //采购入库
|
|
```
|
|
|
|
|
|
>下拉菜单经常需要使用键值对来渲染select的option [{value:desc}]
|
|
|
|
```
|
|
let sourceTypeList =this.$enum.getValueDescList('SOURCE_IN_TYPE')
|
|
//[
|
|
{value: 1, desc: "采购入库"},
|
|
{value: 2, desc: "退货入库"},
|
|
{value: 3, desc: "盘点入库"},
|
|
{value: 4, desc: "取消订单入库"}
|
|
]
|
|
|
|
<Select>
|
|
<Option
|
|
v-for="(item,index) in sourceTypeList"
|
|
:value="item.value"
|
|
:key="index"
|
|
>{{item.desc}}</Option>
|
|
</Select>
|
|
|
|
```
|
|
>根据枚举名获取对应的value描述键值对{value:desc}
|
|
|
|
```
|
|
this.$enum.getValueDesc('SOURCE_IN_TYPE')
|
|
//
|
|
{
|
|
1:"采购入库",
|
|
2:"退货入库",
|
|
3:"盘点入库",
|
|
4:"取消订单入库"
|
|
}
