用于实现多选。
|
|
|
|
## 基本用法
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "/api/mock2/form/saveForm",
|
|
"body": [
|
|
{
|
|
"name": "checkboxes",
|
|
"type": "checkboxes",
|
|
"label": "复选框",
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 显示全选
|
|
|
|
通过 `checkAll` 属性配置全选
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "/api/mock2/form/saveForm",
|
|
"body": [
|
|
{
|
|
"name": "checkboxes",
|
|
"type": "checkboxes",
|
|
"label": "复选框",
|
|
"checkAll": true,
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 按钮模式
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "/api/mock2/form/saveForm",
|
|
"body": [
|
|
{
|
|
"name": "checkboxes",
|
|
"type": "checkboxes",
|
|
"label": "复选框",
|
|
"optionType": "button",
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 按列显示
|
|
|
|
设置 `"inline": false`
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "/api/mock2/form/saveForm",
|
|
"body": [
|
|
{
|
|
"name": "checkboxes",
|
|
"type": "checkboxes",
|
|
"label": "复选框",
|
|
"inline": false,
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 展示多行
|
|
|
|
可以配置`columnsCount`属性调整展示列的个数
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "/api/mock2/form/saveForm",
|
|
"body": [
|
|
{
|
|
"name": "checkboxes1",
|
|
"type": "checkboxes",
|
|
"label": "默认的复选框",
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
}
|
|
]
|
|
},
|
|
{
|
|
"type": "divider"
|
|
},
|
|
{
|
|
"name": "checkboxes2",
|
|
"type": "checkboxes",
|
|
"label": "显示两列的复选框",
|
|
"columnsCount": 2,
|
|
"inline": false,
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
> 1.8.0 及以上版本
|
|
|
|
`columnsCount` 还有一种数组形式，可以手动控制每行显示的列数
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"api": "/api/mock2/form/saveForm",
|
|
"body": [
|
|
{
|
|
"name": "checkboxes1",
|
|
"type": "checkboxes",
|
|
"label": "默认的复选框",
|
|
"columnsCount": [1, 2, 3],
|
|
"options": [
|
|
{
|
|
"label": "OptionA",
|
|
"value": "a"
|
|
},
|
|
{
|
|
"label": "OptionB",
|
|
"value": "b"
|
|
},
|
|
{
|
|
"label": "OptionC",
|
|
"value": "c"
|
|
},
|
|
{
|
|
"label": "OptionD",
|
|
"value": "d"
|
|
},
|
|
{
|
|
"label": "OptionE",
|
|
"value": "e"
|
|
},
|
|
{
|
|
"label": "OptionF",
|
|
"value": "f"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## 分组显示
|
|
|
|
`"inline": false` 下，选项中配置 `children` 字段可以实现分组展示效果。
|
|
|
|
```schema: scope="body"
|
|
{
|
|
"type": "form",
|
|
"mode": "horizontal",
|
|
"debug": true,
|
|
"body": [
|
|
{
|
|
"type": "checkboxes",
|
|
"name": "checkboxes",
|
|
"label": "城市选择",
|
|
"inline": false,
|
|
"checkAll": true,
|
|
"options": [
|
|
{
|
|
"label": "A类型",
|
|
"children": [
|
|
{
|
|
"label": "选项 A-1",
|
|
"value": "a-1"
|
|
},
|
|
{
|
|
"label": "选项 A-2",
|
|
"value": "a-2"
|
|
}
|
|
]
|
|
},
|
|
{
|
|
"label": "B类型",
|
|
"children": [
|
|
{
|
|
"label": "选项 B-1",
|
|
"value": "b-1"
|
|
},
|
|
{
|
|
"label": "选项 B-2",
|
|
"value": "b-2"
|
|
},
|
|
{
|
|
"label": "选项 B-3",
|
|
"value": "b-3"
|
|
},
|
|
{
|
|
"label": "选项 B-4",
|
|
"value": "b-4"
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
]
|
|
}
|
|
```
|
