## 基本用法
```schema:height="200"
{
"type": "page",
"body": {
"type": "mapping",
"value": "1",
"map": {
"1": "第一",
"2": "第二",
"3": "第三",
"*": "其他"
}
}
}
```
## 渲染 HTML
```schema:height="200"
{
"type": "page",
"body": {
"type": "mapping",
"value": "2",
"map": {
"1": "<span class='label label-info'>漂亮</span>",
"2": "<span class='label label-success'>开心</span>",
"3": "<span class='label label-danger'>惊吓</span>",
"4": "<span class='label label-warning'>紧张</span>",
"*": "其他:${type}"
}
}
}
```
## 用作 Field 时
当用在 Table 的列配置 Column、List 的内容、Card 卡片的内容和表单的Static-XXX 中时,可以设置`name`属性,映射同名变量
### Table 中的列类型
```schema:height="300" scope="body"
{
"type": "table",
"data": {
"items": [
{
"id": "1",
"type": "1"
},
{
"id": "2",
"type": "2"
},
{
"id": "3",
"type": "3"
}
]
},
"columns": [
{
"name": "id",
"label": "Id"
},
{
"name": "type",
"label": "映射",
"type": "mapping",
"map": {
"1": "<span class='label label-info'>漂亮</span>",
"2": "<span class='label label-success'>开心</span>",
"3": "<span class='label label-danger'>惊吓</span>",
"4": "<span class='label label-warning'>紧张</span>",
"*": "其他:${type}"
}
}
]
}
```
List 的内容、Card 卡片的内容配置同上
### Form 中静态展示
```schema:height="300" scope="body"
{
"type": "form",
"data": {
"type": "2"
},
"controls": [
{
"type": "static-mapping",
"name": "type",
"label": "映射",
"map": {
"1": "<span class='label label-info'>漂亮</span>",
"2": "<span class='label label-success'>开心</span>",
"3": "<span class='label label-danger'>惊吓</span>",
"4": "<span class='label label-warning'>紧张</span>",
"*": "其他:${type}"
}
}
]
}
```
