[英]MUI v5 - Extending Typography variant in TypeScript creates error "No overload matches this call"
[英]How to type MUI Typography props? v5
我明白我需要做什么,獲得Typography.variant
的類型定義但是我不確定如何真正獲得這些。
interface TextProps {
variant?: string
component?: string
onClick?: (event: React.MouseEvent<HTMLAnchorElement>) => void
}
export const Text = ({ children, variant = 'body1', component = 'body1', onClick }: PropsWithChildren<TextProps>) => {
return (
<Typography variant={variant} component={component} onClick={onClick}>
{children}
</Typography>
)
}
No overload matches this call.
Overload 2 of 2, '(props: DefaultComponentProps<TypographyTypeMap<{}, "span">>): Element', gave the following error.
Type 'string' is not assignable to type '"button" | "caption" | "h1" | "h2" | "h3" | "h4" | "h5" | "h6" | "inherit" | "overline" | "body1" | "subtitle1" | "subtitle2" | "body2" | undefined'. TS2769
我相信這是您可以修復類型錯誤的方法, variant
和component
都不是字符串,您可以在此處查看Typography
類型定義文件以供參考。
import Typography, { TypographyTypeMap } from "@mui/material/Typography";
interface TextProps {
variant?: TypographyTypeMap["props"]["variant"];
component?: React.ElementType;
onClick?: (event: React.MouseEvent<HTMLAnchorElement>) => void;
}
我遇到了同樣的問題,我可以通過這種方式解決。 根據您的代碼:
import React from 'react';
import { Variant } from '@mui/material/styles/createTypography';
interface TextProps {
variant?: Variant
component?: React.ElementType
onClick?: (event: React.MouseEvent<HTMLAnchorElement>) => void
}
export const Text = ({ children, variant = 'body1', component = 'body1', onClick }: PropsWithChildren<TextProps>) => {
return (
<Typography variant={variant} component={component} onClick={onClick}>
{children}
</Typography>
)
}
使用“as”對相關元素進行另一種轉換。 例如:
<Typography variant={variant as Variant } component={component as React.ElementType } onClick={onClick}>
{children}
</Typography>
這種方式在使用平面對象時最常用,但在您使用接口的情況下,最佳實踐是將它們的屬性類型定義到接口中。
豎起大拇指!
