reactjs - 在点击函数式组件时通过 onClick 设置 react 状态(TypeScript)
const NavBar = () => {
const [active, setActive] = useState<string>("tasks");
return {
<Container>
<MenuLink onClick=(() => setActive("settings")/>
<MenuLink onClick=(() => setActive("tasks")/>
<MenuLink onClick=(() => setActive("wallets")/>
</Container>
}
MenuLink.tsx:
interface MenuLinkProps {
$active: boolean;
to: string;
title: string;
}
function MenuLink({ $active, to, title, ...rest }: MenuLinkProps) {
return (
<Container $active={$active} to={to} {...rest}>
{title}
</Container>
);
}
interface ContainerProps {
$active: boolean;
to: string;
}
const Container = styled(Link)<ContainerProps>`
width: 70px;
height: 35px;
display: flex;
justify-content: center;
align-items: center;
border-radius: 3px;
font-style: normal;
font-weight: 500;
font-size: 14px;
line-height: 17px;
letter-spacing: 0.025em;
text-decoration: none;
color: ${({ $active }: ContainerProps) => ($active ? "#4C6C94" : "#908E87")};
background: ${({ $active }: ContainerProps) => ($active ? "#1D232B;" : "#100F0D")};
&:not(:first-child) {
margin-left: 24px;
}
`;
我想在每次点击 MenuLink 项时触发 setActive。然而,TypeScript 抱怨我在 MenuLinkProps 中没有 onClick 作为属性。我不确定这是否正确,因为当我把 onClick 作为属性时,我会得到这个错误:
Cannot update a component (`NavBar`) while rendering a different component (`MenuLink`). To locate the bad setState() call inside `MenuLink`, follow the stack trace as described in我不太确定应该如何在自定义组件中使用 onClick(以及其他标准“props”)。
答案#1
你可以更改你的导航栏界面为
interface MenuLinkProps {
$active: boolean;
to: string;
title: string;
[key : string] : any
}
接受静态的任何属性 这不会修复你的错误,请提供你在哪里以及如何使用 $active
答案#2
所以,你将必须将父组件的点击方法作为 props 传递给子组件
父组件:
const NavBar = () => {
const [active, setActive] = useState<string>("tasks");
var menuOnClick: (action:string) => {setActive(action)};
return {
<div>
<Container>
<MenuLink onClick=(this.menuOnClick} />
<MenuLink onClick=(this.menuOnClick} />
<MenuLink onClick=(this.menuOnClick} />
</Container>
</div>
}
}
子组件:
<Container $active={$active} to={to} {...rest} onClick ={() => this.props.onClick(title)} >
{title}
</Container>
