使用 Css 模块将条件转换样式添加到我的侧边导航
Use Css modules add conditional transition styling to my side navigation
我想在我的应用程序的侧面导航中添加一些过渡样式。我可以使用普通 类 来做到这一点,但是在本教程中他们使用 css 模块,我不确定如何使用 css 模块来做到这一点。
我希望我的导航能够滑入和滑出,在 onClick 函数触发时它会静态跳跃 - toggleSideDrawer
。
我已经使用了这个逻辑,但我不确定它是否在做任何事情:
className={props.toggleSideDrawer ? classes.SideDrawerOpen : classes.SideDrawer
基本上我希望当用户单击切换时,transform
属性 从 translateX(-100%)
切换到 translateX(0)
但这并没有发生。
侧面导航代码:
import React from "react";
import Logo from "../../Logo/Logo";
import NavigationItems from "../NavigationItems/NavigationItems";
import Backdrop from "../../UI/Backdrop/Backdrop";
import Aux from "../../../hoc/Aux";
import classes from "./SideDrawer.css";
const SideDrawer = props => {
return (
<Aux classname={classes.SideDrawer}>
<Backdrop
showBackdrop={props.showSideDrawer}
clicked={props.toggleSideDrawer}
/>
{props.showSideDrawer && (
<div
onClick={props.toggleSideDrawer}
className={
props.toggleSideDrawer ? classes.SideDrawerOpen : classes.SideDrawer
}
>
<div className={classes.Logo}>
<Logo />
</div>
<nav>
<NavigationItems />
</nav>
</div>
)}
</Aux>
);
};
export default SideDrawer;
代码在我的布局组件中使用的地方:
import React, { useState } from "react";
import Aux from "../Aux";
import classes from "./Layout.css";
import Toolbar from "../../components/Navigation/Toolbar/Toolbar";
import SideDrawer from "../../components/Navigation/SideDrawer/SideDrawer";
const layout = props => {
const [showSideDrawer, setShowSideDrawer] = useState(false);
return (
<Aux>
<SideDrawer
showSideDrawer={showSideDrawer}
toggleSideDrawer={() => {
setShowSideDrawer(!showSideDrawer);
}}
/>
<Toolbar
onMenuClick={() => {
setShowSideDrawer(!showSideDrawer);
}}
/>
<main className={classes.mainContent}> {props.children} </main>
</Aux>
);
};
export default layout;
CSS:
.SideDrawer {
position: fixed;
width: 280px;
max-width: 70%;
height: 100%;
left: 0;
top: 0;
z-index: 200;
background-color: white;
padding: 32px 16px;
box-sizing: border-box;
transform: translateX(-100%);
}
@media (min-width: 500px) {
.SideDrawer {
display: none;
}
}
.Logo {
height: 11%;
text-align: center;
}
.SideDrawerOpen {
position: fixed;
width: 280px;
max-width: 70%;
height: 100%;
left: 0;
top: 0;
z-index: 200;
padding: 32px 16px;
box-sizing: border-box;
background-color: red;
transform: translateX(0);
transition: transform 0.3s ease-out;
}
问题是您需要元素始终transition
规则。
我的建议是设置一个静态 class 来保存所有样式,并添加 另一个 仅用于覆盖 transform
以使其移动.
类似的东西(它使用 scss 但使用 css 很容易做到)
.SideDrawer {
position: fixed;
width: 280px;
max-width: 70%;
height: 100%;
left: 0;
top: 0;
z-index: 200;
background-color: white;
padding: 32px 16px;
box-sizing: border-box;
transition: transform .3s ease;
transform: translateX(-100%);
&.show {
transform: translateX(0);
}
}
export const App = () => {
const [showSideDrawer, setShowSideDrawer] = useState(false);
const sidebarClasses = classname([
styles.SideDrawer,
{
[styles.show]: showSideDrawer
}
]);
const ToggleSidebar = () => {
return (
<button onClick={() => setShowSideDrawer(!showSideDrawer)}>
Toggle Sidebar
</button>
);
};
return (
<Fragment>
<h1>App</h1>
<div className={sidebarClasses}>
<div>Sidebar content</div>
<ToggleSidebar />
</div>
<ToggleSidebar />
</Fragment>
);
};

@MoshFeu 帮我解决了这个问题。
问题是您仅在 showSideDrawer 时渲染抽屉,因此在它变为 true 之前,边栏不在 DOM 中,因此过渡不会影响它。
解决方案是一直将其保留在 DOM 中,但切换 。打开class更改样式。
有些库知道即使对于不在 DOM 中的元素也可以进行转换,但它有点复杂。
SideDrawer.js 的代码修复 return
中没有条件
class SideDrawer extends Component {
render() {
let sideDrawerClass = [classes.SideDrawer];
// SideDrawer will now be an array with the side drawer classes and the open class
if (this.props.showSideDrawer) {
sideDrawerClass.push(classes.Open);
}
return (
<Aux classname={classes.SideDrawer}>
<Backdrop
showBackdrop={this.props.showSideDrawer}
clicked={this.props.toggleSideDrawer}
/>
<div
className={sideDrawerClass.join(" ")}
onClick={this.props.toggleSideDrawer}
>
<div className={classes.Logo}>
<Logo />
</div>
<nav>
<NavigationItems />
</nav>
</div>
</Aux>
);
