**表单项** 是组成一个表单的基本单位,它具有的一些特性会帮助我们更好地实现表单操作。
|
|
|
|
|
|
|
|
|
|
> 所有派生自`FormItem`的组件,都具有`FormItem`的特性。
|
|
|
|
|
|
|
|
|
|
## 基本用法
|
|
|
|
|
|
|
|
|

|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-06-04 10:27:19 +08:00
|
|
|

|
|
"label": "极小",
|
|
|
|
|
"name": "text-xs",
|
|
|
|
|
"size": "xs"
|
|
|

|
|
|
|
> 不同组件的`size`效果可能会有所不同,具体请参考对应的组件文档。
|
|
|
|
|
|
|
|
|
|
### 表单项标签
|
|
|
|
|
|
|
|
|
|
设置`label`属性来配置表单项标签。
|
|
|
|
|
|
|
|
|
|
当表单为水平布局时,左边即便是不设置`label`为了保持对齐也会留空,如果想要去掉空白,请设置成`false`。

|
|
|
|
|
|
|
|
|
|
通过配置`"disabled": true`来禁用表单项
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|

|
|
|
|
|

```
|

|
## 表单项值
|
|
|
|
|
|
|
|
|
|
表单项值,即表单项通过用户交互发生变化后,更新表单数据域中同`name`变量值.
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"debug": true,
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "姓名",
|
|
|
|
|
"name": "name"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如上例,更改姓名表单项值,可以改变表单数据域中`name`变量的值。
|
|
|
|
|
|
2020-08-03 16:06:22 +08:00
|
|
|
|
也支持链式配置 `name`属性,例如:`aaa.bbb`
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-08-03 16:06:22 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"debug": true,
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-08-03 16:06:22 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-08-03 16:06:22 +08:00
|
|
|
|
"label": "姓名",
|
|
|
|
|
"name": "person.name"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
观察上例,这样更改表单项值,会改变数据域中`person.name`的值
|
|
|
|
|
|
|
|
|
|
```json
|
|
|
|
|
{
|
|
|
|
|
"person": {
|
|
|
|
|
"name": "xxx"
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
2020-07-28 10:03:53 +08:00
|
|
|
|
## 配置默认值
|
|
|
|
|
|
|
|
|
|
通过配置`value`属性,可以设置表单项的默认值。
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "text",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"value": "hello world!",
|
|
|
|
|
"description": "拥有默认值的 text"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
`value`不支持数据映射,也就是说不可以直接配置类似于这样的语法:`${xxx}`,如果想要映射当前数据域中的某个变量,那么设置该表单项`name`为该变量名就行,如下:
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"data":{
|
|
|
|
|
"text": "hello world!"
|
|
|
|
|
},
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "text",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"description": "拥有默认值的 text"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
上例中我们表单数据域中有变量`"text": "hello world!"`,然后我们设置表达项`"name": "text"`,这样就可以自动映射值了。
|
|
|
|
|
|
2021-01-28 14:44:16 +08:00
|
|
|
|
## 隐藏时删除表单项值
|
|
|
|
|
|
|
|
|
|
默认情况下,在通过 `hiddenOn` 或 `visibleOn` 配置显隐交互时,被隐藏的表单项值,不会在当前表单数据域中删除,例如:
|
|
|
|
|
|
|
|
|
|
```schema: scope="body"
|
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"debug":"true",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2021-01-28 14:44:16 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-number",
|
2021-01-28 14:44:16 +08:00
|
|
|
|
"label": "数量",
|
|
|
|
|
"name": "number",
|
|
|
|
|
"value": 0,
|
|
|
|
|
"description": "调整数量大小查看效果吧!"
|
|
|
|
|
},
|
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2021-01-28 14:44:16 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"value":"这是一段文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"hiddenOn": "this.number > 1",
|
|
|
|
|
"description": "当数量大于1的时候,该文本框会隐藏"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
观察上例,在调整 `number` 数量大于 1 时,`文本` 表单项会隐藏,但是对应的表单数据域中的 `text` 变量值仍存在。
|
|
|
|
|
|
|
|
|
|
如果想要实现隐藏表单项后,在当前表单数据域中删除该表单项对应的值,那么可以在当前表单项上配置 `"clearValueOnHidden": true`。
|
|
|
|
|
|
|
|
|
|
```schema: scope="body"
|
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"debug":"true",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2021-01-28 14:44:16 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-number",
|
2021-01-28 14:44:16 +08:00
|
|
|
|
"label": "数量",
|
|
|
|
|
"name": "number",
|
|
|
|
|
"value": 0,
|
|
|
|
|
"description": "调整数量大小查看效果吧!"
|
|
|
|
|
},
|
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2021-01-28 14:44:16 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"value":"这是一段文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"hiddenOn": "this.number > 1",
|
|
|
|
|
"description": "当数量大于1的时候,该文本框会隐藏",
|
|
|
|
|
"clearValueOnHidden": true
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
再次观察上例,当 `文本` 表单项隐藏时,对应的 `text` 变量也会被删除掉。
|
|
|
|
|
|
|
|
|
|
> 注意: 如果有其他同 name 的表达项的存在,即使其他表单项值没有隐藏,也会在数据域中删掉该值。
|
|
|

|
|
|
|
|
|
|
|
|
### 静态配置
|
|
|
|
|
|
|
|
|
|
通过配置`"required": true`来标识该表单项为必填。
|
|

|
|
2021-01-07 23:35:03 +08:00
|
|
|

### 满足条件校验必填
|
|
|
|
|
|
2021-02-01 20:44:49 +08:00
|
|
|
|
你也通过[表达式](../../../docs/concepts/expression)配置`requiredOn`,来实现在某个条件下使当前表单项必填。

## 格式校验
|
|
|
|
|
|
|
|
|
|
可以配置`validations`属性,指定校验当前表单项值的格式
|
|
|
|
|
|
|
|
|

2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"validations": {
|
|
|

|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
同样也可以配置多个格式校验
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
|
"api": "/api/mock2/form/saveForm",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"validations": {
|
|
|
|
|
"isNumeric": true,
|
|
|
|
|
"minimum": 10
|
|
|
|
|
},
|
|
|
|
|
"description": "请输入数字类型文本"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 字符串形式(不推荐)
|
|
|
|
|
|
|
|
|
|
也可以配置字符串形式来指定,如下例,输入不合法的值,点击提交会报错并显示报错信息
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
|
"api": "/api/mock2/form/saveForm",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"validations": "isNumeric",
|
|
|
|
|
"description": "请输入数字类型文本"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
也可以指定多个格式校验,中间用`逗号`分隔。
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
|
"api": "/api/mock2/form/saveForm",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"validations": "isNumeric,minimum:10",
|
|
|
|
|
"description": "请输入数字类型文本"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如果需要配置参数,例如显示最大值或最小值,则在格式标识符后`:`和参数
|
|
|
|
|
|
|
|
|
|
### 自定义校验信息
|
|
|
|
|
|
|
|
|
|
amis 会有默认的报错信息,如果你想自定义校验信息,配置`validationErrors`属性
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
|
"api": "/api/mock2/form/saveForm",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "文本",
|
|
|
|
|
"name": "text",
|
|
|
|
|
"validations": {
|
|
|
|
|
"isNumeric": true
|
|
|
|
|
},
|
|
|
|
|
"validationErrors": {
|
|
|
|
|
"isNumeric": "同学,请输入数字哈"
|
|
|
|
|
},
|
|
|
|
|
"description": "请输入数字类型文本"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
如果需要获取当前格式校验配置的参数,可以使用`$1`
|
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|

### 表单项值发生变化即校验
|
|
|
|
|
|
2021-07-19 20:37:32 +08:00
|
|
|
|
默认校验是当进行行为操作时,对表单项进行校验,如果你想每次表单项的值发生变化的时候就校验,请配置`"validateOnChange": true`
|
2020-07-28 10:03:53 +08:00
|

### 自定义校验函数
|
|
|
|
|
|
2021-03-06 11:15:55 +08:00
|
|
|
|
可以自己写代码扩展表单验证,请参考 [这里](../../docs/extend/addon#扩展表单验证)
|
2021-01-11 12:00:41 +08:00

## 服务端校验
|
|
|
|
|
|
2021-06-24 17:31:44 +08:00
|
|
|
|
### 通过表单提交接口
|
|
|
|
|
|
|
|
|
|
也可以通过表单提交接口返回错误信息,实现服务端校验
|
2020-07-28 10:03:53 +08:00
|
|
|
|
|
2021-01-07 23:35:03 +08:00
|
|
|
|
```schema: scope="body"
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
2021-08-09 18:05:01 +08:00
|
|
|
|
"api": "/api/mock2/form/saveFormFailed?waitSeconds=1",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"body": [
|
2020-07-28 10:03:53 +08:00
|
|
|
|
{
|
|
|
|
|
"name": "test2",
|
2021-06-04 10:27:19 +08:00
|
|
|
|
"type": "input-text",
|
2020-07-28 10:03:53 +08:00
|
|
|
|
"label": "服务端验证"
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
2020-07-29 16:20:21 +08:00
|
|
|
|
点击提交,api 接口返回中,需要在 errors 变量中,返回某个表单项的报错信息,`key`值为该表单项的`name`值。
|
2020-07-28 10:03:53 +08:00
|
|
|
|
|
|
|
|
|
如上,接口返回的格式如下,提交后,`test2`表达项会显示报错信息
|
|
|
|
|
|
|
|
|
|
```json
|
|
|
|
|
{
|
|
|
|
|
"status": 422, // 返回非0状态码
|
|
|
|
|
"msg": "",
|
|
|
|
|
"errors": {
|
|
|
|
|
"test2": "服务器端说,这个有错误。"
|
|
|
|
|
},
|
|
|
|
|
"data": null
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
2021-06-24 17:31:44 +08:00
|
|
|
|
#### Combo 校验
|
2021-01-07 23:32:07 +08:00
|
|
|
|
|
|
|
|
|
Combo 类型的表单项,要实现服务端校验,可以使用 `路径key` 来定位要显示报错信息的表单项,例如 `a[0].b` 定位到 a combo 的第一项中 b 表单项。
|
|
|
|
|
|
|
|
|
|
例如有如下表单,点击提交,查看效果:
|
|
|
|
|
|
|
|
|
|
```schema:scope="body"
|
|
|
|

#### Table 校验
|
2021-01-26 18:12:02 +08:00
|
|
|
|
|
|
|
|
|
Table 类型的表单项,要实现服务端校验,可以使用 `路径key` 来定位要显示报错信息的表单项,例如 `a[0].b` 定位到 a table 的第一项中 b 表单项。
|
|
|
|
|
|
|
|
|
|
例如有如下表单,点击提交,查看效果:
|
|

### 通过表单项校验接口
|
|
|
|
|
|
|
|
|
|
可以在表单项上,配置校验接口 `validateApi`,实现单个表单项后端校验。
|
|
|
|
|
|
|
|
|
|
```schema:scope="body"
|
|
|
|
|
{
|
|
|
|
|
"type": "form",
|
|
|
|
|
"mode": "horizontal",
|
|
|
|
|
"api": "/api/mock2/form/saveForm",
|
|
|
|
|
"body": [
|
|
|
|
|
{
|
|
|
|
|
"label": "name",
|
|
|
|
|
"type": "input-text",
|
|
|
|
|
"name": "name",
|
|
|
|
|
"required": true,
|
|
|
|
|
"validateApi": "/api/mock2/form/formitemFailed"
|
|
|
|
|
},
|
|
|
|
|
{
|
|
|
|
|
"label": "email",
|
|
|
|
|
"type": "input-text",
|
|
|
|
|
"name": "email",
|
|
|
|
|
"validateApi": "/api/mock2/form/formitemSuccess",
|
|
|
|
|
"required": true
|
|
|
|
|
}
|
|
|
|
|
]
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
校验接口显示校验信息返回格式如下:
|
|
|
|
|
|
|
|
|
|
```json
|
|
|
|
|
{
|
|
|
|
|
"status": 422,
|
|
|
|
|
"errors": "当前用户已存在"
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
- `status`: 返回 `0` 表示校验成功,`422` 表示校验失败;
|
|
|
|
|
- `errors`: 返回 `status` 为 `422` 时,显示的校验失败信息;
|
