Formik Material UI React - 自动完成 - 从不受控制状态到受控状态
我正在尝试弄清楚如何按照 此处 中 Formik、Material UI、React 工具的 Autocomplete 字段文档中的说明进行操作。
文档中给出的示例是:
import { Autocomplete } from 'formik-material-ui-lab';
const options = [{ title: 'The Shawshank Redemption', year: 1994 }, ...]
<Field
name="name"
component={Autocomplete}
options={options}
getOptionLabel={(option: Movie) => option.title}
style={{ width: 300 }}
renderInput={(params: AutocompleteRenderInputParams) => (
<TextField
{...params}
error={touched['name'] && !!errors['name']}
helperText={errors['name']}
label="Autocomplete"
variant="outlined"
/>
)}
/>;
没有给出 Movie 在 getOptionLabel 中的含义的线索。当我尝试使用它时,Movie 会带有下划线,就像 renderInput 对象中的 AutocompleteRenderInputParams 一样。我不知道为什么。
我看过这个 帖子 ,它尝试了一种替代方法,但我也无法让它工作。
我有一个表单,带有两个自动完成字段。目前,它看起来像这样。
当我尝试使用表单时,提交按钮挂起,控制台日志显示:
Material-UI: The
getOptionLabel
method of Autocomplete returned undefined instead of a string for "".

有人能看到如何让自动完成功能与 formik、material ui 配合使用,与上面链接中发布的文档一致吗?
我也尝试使用常规的选择表单输入。这是表单字段:
<Box margin={1}>
<Field
component={TextField}
type="text"
name="category"
label="Category"
select
variant="outlined"
helperText="Select a category"
margin="normal"
style={{ width: "100%"}}
InputLabelProps={{
shrink: true,
}}
>
{allCategories.map(option => (
<MenuItem key={option.value} value={option.value}>
{option.label}
</MenuItem>
))}
</Field>
当我尝试此操作时,控制台中出现一条警告,内容为:
instrument.ts:129 Material-UI: You have provided an out-of-range value `undefined` for the select component.
Consider providing a value that matches one of the available options or ''
此警告毫无意义 - 表单会呈现正确填充的菜单。
我还收到一条错误消息,内容为:
index.js:1 Warning: A component is changing an uncontrolled input of type undefined to be controlled. Input elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled input element for the lifetime of the component. More info
关于该错误,我看过此 帖子 ,其中建议使用值(而不是输入 - 我就是这么做的)并将所有初始值定义为类型。对我来说,它们都是字符串,尽管我尝试用空数组替换选择字段。在这两种选择中,控制台中都会返回相同的错误消息。
此时 - 我不在乎使用自动完成还是选择,我只想让其中一个工作。
有趣的是,在这两种情况下(使用选择和自动完成),控制台都会记录警告,内容是:
Material-UI: You have provided an out-of-range value `undefined` for the select component.
Consider providing a value that matches one of the available options or ''.
The available values are `one`, `two`.
(anonymous) @ 0.chunk.js:141301
0.chunk.js:141301 Material-UI: You have provided an out-of-range value `undefined` for the select component.
Consider providing a value that matches one of the available options or ''.
The available values are `a`, `b`, `c`, `d`.
但是,只有一个错误实例显示:
A component is changing an uncontrolled input of type undefined to be controlled. Input elements should not switch from uncontrolled to controlled (or vice versa). Decide between using a controlled or uncontrolled input element for the lifetime of the component. More info: react-website -controlled-components

in ForwardRef(SelectInput) (created by ForwardRef(InputBase))
in div (created by ForwardRef(InputBase))
in ForwardRef(InputBase) (created by WithStyles(ForwardRef(InputBase)))
in Wi
此错误指向类别选择表单输入。
我还尝试将此 代码沙箱 中的性别选择表单字段添加到我的表单中,看看我是否可以让它工作。当我注释掉上面描述的类别和共享字段,并添加默认值为空字符串的性别字段时,表单会加载。
字段为:
<Field
name="gender"
label="Gender"
options={[
{ value: "Male", label: "Male" },
{ value: "Female", label: "Female" },
{ value: "Other", label: "Other" }
]}
component={Select}
/>
性别选择字段出现,但宽度约为 1 厘米,选项菜单没有填充选项,我无法选择任何内容。但表单确实加载到 firebase,性别字段中有一个空字符串。这是进步,但不足以继续前进。
同一代码沙箱显示了一个使用自动完成的字段。我尝试对其进行调整并在我的表单中使用它,如下所示:
<Field
name="gender"
label="Gender"
options={sharingOptions}
component={Autocomplete}
textFieldProps={{
label: sharingOptions.label
}}
/>
当我尝试这样做时,我收到一条错误消息:
TypeError: renderInput is not a function
此错误消息对我来说毫无意义,因为我在表单的任何地方都没有使用 renderInput。
当我尝试:
<Box margin={1}>
<Field
component={Select}
type="text"
name="category"
label="Impact Category"
select
variant="outlined"
helperText="Select a category"
margin="normal"
style={{ width: "100%"}}
InputLabelProps={{
shrink: true,
}}
>
{allCategories.map(option => (
<MenuItem key={option.value} value={option.value}>
{option.label}
</MenuItem>
))}
</Field>
</Box>
我没有收到任何错误,并且可以保存带有选项详细信息的表单。但是,这实际上并没有解决自动完成不起作用的问题。这也没有使用链接文档中所示的选择字段。所以我不清楚为什么这样做有效,或者为什么文档中显示的方法不起作用。
下次尝试
使用此 codesandbox 中的自动完成示例作为指南,我尝试:
<Field
name="autocomplete"
multiple
component={Autocomplete}
options={sharingOptions}
getOptionLabel={(option: any) => option.title}
style={{width: 300}}
renderInput={(params: AutocompleteRenderInputParams) => (
<MuiTextField
{...params}
error={touched['autocomplete'] && !!errors['autocomplete']}
helperText={touched['autocomplete'] && errors['autocomplete']}
label="Autocomplete"
variant="outlined"
/>
)}
/>
与前面的示例一样,我的代码编辑器在 getOptionLabel 中出现的值“any”下划线,并且还强调了 AutocompleteRenderInputParams。我找不到任何文档来解释表单字段的这些元素的含义或作用。无论如何,我已导入 AutocompleteRenderInputParams,如代码沙箱中所示。
我将表单中自动完成字段的初始值设为一个空数组 - 尽管我注意到代码沙箱在此示例中未设置初始值。当我尝试删除自动完成的初始值时,我得到的错误与初始值为空数组时生成的错误相同,但我还在控制台中收到一条警告,内容为:
Warning: value for autocomplete is not an array, this can caused unexpected behaviour
当我尝试此代码时,我的控制台记录了以下错误:
TypeError: Cannot read property 'toLowerCase' of undefined
Material-UI: The
getOptionLabel
method of Autocomplete returned undefined instead of a string for {"value":"open","label":"Open "}.
工作示例:
演示
import React from "react";
import ReactDOM from "react-dom";
import "./styles.css";
import { Formik, Field } from "formik";
import { Autocomplete } from "formik-material-ui-lab";
import { TextField } from "@material-ui/core";
const options = [
{ title: "The Shawshank Redemption", year: 1994 },
{ title: "Inglourious Basterds", year: 2009 },
{ title: "Snatch", year: 2000 },
{ title: "3 Idiots", year: 2009 },
{ title: "Monty Python and the Holy Grail", year: 1975 }
];
function App() {
return (
<Formik
initialValues={{
autocomplete: null
}}
>
{() => (
<Field
name="autocomplete"
component={Autocomplete}
options={options}
getOptionLabel={(option) => option.title}
style={{ width: 300 }}
renderInput={(params) => (
<TextField {...params} label="Autocomplete" variant="outlined" />
)}
/>
)}
</Formik>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
对于其他遇到困难的人来说,这种方法很管用 - 虽然我不明白为什么。上面帖子中指出的下划线错误仍然存​​在,我不知道如何解决它们。
分享此内容作为一种前进的方式 - 而不是一种好的解决方案。
