## 基本使用
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "form",
"api": "/api/mock2/form/saveForm",
2021-06-03 22:09:30 +08:00
"body": [
2020-07-28 10:03:53 +08:00
{
"name": "text",
2021-06-03 22:09:30 +08:00
"type": "input-text",
2020-07-28 10:03:53 +08:00
"label": "text"
}
]
}
```
## 不同类型
配置`type`可以支持不同格式的文本输入框
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "form",
"api": "/api/mock2/form/saveForm",
2021-06-03 22:09:30 +08:00
"body": [
2020-07-28 10:03:53 +08:00
{
"name": "text",
2021-06-03 22:09:30 +08:00
"type": "input-text",
2020-07-28 10:03:53 +08:00
"label": "text"
},
{
"type": "divider"
},
{
2021-06-03 22:09:30 +08:00
"type": "input-url",
2020-07-28 10:03:53 +08:00
"name": "url",
"label": "链接"
},
{
"type": "divider"
},
{
2021-06-03 22:09:30 +08:00
"type": "input-email",
2020-07-28 10:03:53 +08:00
"name": "email",
"label": "邮箱"
},
{
"type": "divider"
},
{
2021-06-03 22:09:30 +08:00
"type": "input-password",
2020-07-28 10:03:53 +08:00
"name": "password",
"label": "密码"
}
]
}
```
## 附加组件
可以配置`addOn`,附带附加组件,比如 button还能设置 icon。
2020-07-28 10:03:53 +08:00
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "form",
"api": "/api/mock2/form/saveForm",
2021-06-03 22:09:30 +08:00
"body": [
2020-07-28 10:03:53 +08:00
{
"name": "text",
2021-06-03 22:09:30 +08:00
"type": "input-text",
2020-07-28 10:03:53 +08:00

"label": "搜索"
}
}
]
}
```

## 可清除
通过 `"clearable": true` 可以设置文本可清除
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
2021-06-03 22:09:30 +08:00
"body": [
2021-03-19 09:40:59 +08:00
{
"name": "text",
2021-06-03 22:09:30 +08:00
"type": "input-text",
2021-03-19 09:40:59 +08:00
"label": "text",
2021-03-26 16:11:09 +08:00
"clearable": true
2021-03-19 09:40:59 +08:00
}
]
}
```
2020-07-28 10:03:53 +08:00
## 选择器模式
配置`options`即可支持选择器模式。
```schema: scope="body"
2020-07-28 10:03:53 +08:00
{
"type": "form",
"api": "/api/mock2/form/saveForm",
2021-06-03 22:09:30 +08:00
"body": [
2020-07-28 10:03:53 +08:00
{
"name": "text",
2021-06-03 22:09:30 +08:00
"type": "input-text",
2020-07-28 10:03:53 +08:00
"label": "text",
"options": [
{
"label": "aa",
"value": "aa"
},
{
"label": "bb",
"value": "bb"
},
{
"label": "cc",
"value": "cc"
},
{
"label": "dd",
"value": "dd"
}
]
}
]
}
```
选择器模式下支持部分选择器组件支持的配置项具体请查看下面的属性表。如source 和 autoComplete 都支持
## 限制只能选择预设
配置 options 并且配置 creatable: false
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"body": [
{
"name": "text",
"type": "input-text",
"label": "text",
"creatable": false,
2020-07-28 10:03:53 +08:00
"options": [
{
"label": "OptionA",
"value": "a"
},
{
"label": "OptionB",
"value": "b"
},
{
"label": "OptionC",
"value": "c"
},
{
"label": "OptionD",
"value": "d"
}
]
}
]
}
```
## 多选模式
配置 multiple: true
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"debug": true,
"body": [
{
"name": "text",
"type": "input-text",
"label": "text",
"multiple": true,
"options": [
{
"label": "OptionA",
"value": "a"
},
{
"label": "OptionB",
"value": "b"
},
{
"label": "OptionC",
"value": "c"
},
{
"label": "OptionD",
"value": "d"
}
]
}
]
}
```
2020-07-28 10:03:53 +08:00
## 前缀和后缀
```schema: scope="body"
{
"type": "form",
"api": "/api/mock2/form/saveForm",
"data": {
"unit": "MB"
},
"body": [
{
"name": "text",
"type": "input-text",
"label": "text",
"prefix": "¥",
"suffix": "RMB"
},
{
"name": "prefix",
"type": "input-text",
"label": "text",
"prefix": "¥"
},
{
"name": "suffix",
"type": "input-text",
"label": "text",
"suffix": "${unit}"
}
]
}
```
支持数据映射
## 显示计数器
```schema: scope="body"
{
"type": "form",
"body": [
{
"name": "a",
"type": "input-text",
"label": "A",
"showCounter": true,
"placeholder": "请输入"
},
{
"name": "b",
"type": "input-text",
"label": "B",
"showCounter": true,
"maxLength": 100,
"placeholder": "请输入"
}
]
}
```
## 自动转换值
可以配置 transform来自动转换值支持转小写或大写。
> 注意下面第一个示例,只有输入的内容才会触发 transform下拉框选中的值是不会处理的。
```schema: scope="body"
{
"type": "form",
"debug": true,
"body": [
{
"name": "lower",
"type": "input-text",
"label": "转换小写",
"placeholder": "输入的英文自动转为小写",
"transform": {
"lowerCase": true
},
"multiple": true,
"options": ["APPLE", "ORANGE", "WATERMELON"],
},
{
"name": "upper",
"type": "input-text",
"label": "转换大写",
"placeholder": "输入的英文自动转为大写",
"transform": {
"upperCase": true
}
}
]
}
```

## 事件表
2022-05-31 15:05:54 +08:00
当前组件会对外派发以下事件,可以通过`onEvent`来监听这些事件,并通过`actions`来配置执行的动作,在`actions`中可以通过`event.data.xxx`事件参数变量来获取事件产生的数据,详细请查看[事件动作](../../docs/concepts/event-action)。
| 事件名称 | 事件参数 | 说明 |
| -------- | --------------------------------- | -------------------- |
| click | `event.data.value: string` 输入值 | 点击输入框时触发 |
| focus | `event.data.value: string` 输入值 | 输入框获取焦点时触发 |
| blur | `event.data.value: string` 输入值 | 输入框失去焦点时触发 |
| enter | `event.data.value: string` 输入值 | 回车时触发 |
| change | `event.data.value: string` 输入值 | 值变化时触发 |
## 动作表
2022-05-31 15:05:54 +08:00
当前组件对外暴露以下特性动作,其他组件可以通过指定`actionType: 动作名称`、`componentId: 该组件id`来触发这些动作,动作配置可以通过`args: {动作配置项名称: xxx}`来配置具体的参数,详细请查看[事件动作](../../docs/concepts/event-action#触发其他组件的动作)。
| 动作名称 | 动作配置 | 说明 |
| -------- | ------------------------ | -------------------------------------------------- |
