如何使用 Tailwind CSS 实用程序类使部分粘性

在我的 Next.js Web 应用程序中，我有一个页面，如下所示：我想让该部分（用标签包裹）以蓝色粘性突出显示，这样当我滚动时，它会保持在原来的位置，并且只有 m... 在我的 Next.js Web 应用程序中，我有一个页面，如下所示：我想使该部分（包含在 <aside> 标签中）以蓝色粘性突出显示，这样当我滚动时，它会保持在原来的位置，并且只有主要部分（包含图表的部分）会滚动。这是 layout.tsx 文件： import { dashboardConfig } from "@/config/dashboard"; import { MainNav } from "@/components/nav/main-nav"; import { DashboardNav } from "@/components/nav/dashboard-nav"; interface DashboardLayoutProps { children?: React.ReactNode; } export default async function DashboardLayout({ children, }: DashboardLayoutProps) { return ( <div className="flex min-h-dvh flex-col relative"> <header className="container z-40 bg-background"> <MainNav /> </header> <div className="container grid flex-1 gap-12 md:grid-cols-[200px_1fr] mt-32 mb-12 relative"> <aside className="hidden w-[200px] flex-col md:flex sticky top-0"> <DashboardNav items={dashboardConfig.sidebarNav} /> </aside> <main className="flex w-full flex-1 flex-col overflow-hidden"> {children} </main> </div> </div> ); } 请注意，我已将类 sticky 和 top-0 应用于我想要粘贴位置的部分。但它不起作用。我做错了什么？考虑通过 align-self: start 将 self-start 应用到粘性元素。默认情况下，它将具有 align-self: stretch，这将使其成为其父网格元素的完整高度，因此不会观察到粘性效果。通过应用 align-self: start，它的高度将仅与其内容一样高，如果存在垂直自由空间，则可以观察到粘性效果。 const dashboardConfig = { sidebarNav: '' }; const MainNav = () => 'MainNav'; const DashboardNav = () => 'DashboardNav'; function DashboardLayout({ children, }) { return ( <div className="flex min-h-dvh flex-col relative"> <header className="container z-40 bg-background"> <MainNav /> </header> <div className="container grid flex-1 gap-12 md:grid-cols-[200px_1fr] mt-32 mb-12 relative"> <aside className="hidden w-[200px] flex-col md:flex sticky top-0 self-start"> <DashboardNav items={dashboardConfig.sidebarNav} /> </aside> <main className="flex w-full flex-1 flex-col overflow-hidden"> {children} </main> </div> </div> ); } function App() { return ( <DashboardLayout> <div class="h-[200vh]"></div> </DashboardLayout> ); } ReactDOM.createRoot(document.getElementById('app')).render(<App/>); <script src="https://cdnjs.cloudflare.com/ajax/libs/react/18.2.0/umd/react.production.min.js" integrity="sha512-8Q6Y9XnTbOE+JNvjBQwJ2H8S+UV4uA6hiRykhdtIyDYZ2TprdNmWOUaKdGzOhyr4dCyk287OejbPvwl7lrfqrQ==" crossorigin="anonymous" referrerpolicy="no-referrer"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/18.2.0/umd/react-dom.production.min.js" integrity="sha512-MOCpqoRoisCTwJ8vQQiciZv0qcpROCidek3GTFS6KTk2+y7munJIlKCVkFCYY+p3ErYFXCjmFjnfTTRSC1OHWQ==" crossorigin="anonymous" referrerpolicy="no-referrer"></script> <script src="https://cdn.tailwindcss.com/3.4.1"></script> <div id="app"></div>

具有多个值的JS var

有件事我无法理解：我有一个打开同一页面的功能，但具有不同的内容，具体取决于菜单中单击的按钮：有件事我无法理解：我有一个打开同一页面的功能<div id="page">但具有不同的内容，具体取决于菜单中单击的按钮： <nav> <button onclick="openPage(1)">PAGE 1</button> <button onclick="openPage(2)">PAGE 2</button> <button onclick="openPage(3)">PAGE 3</button> </nav> 然后是函数： function openPage(p){ var move=0; // define a var for USER action if(p==1){ document.getElementById('page').innerHTML = text_1; // content preloaded } else if(p==2){ document.getElementById('page').innerHTML = text_2; } else if(p==3){ document.getElementById('page').innerHTML = text_3; } // then on the top of the page (absolute + z-index) I add a HTML object: document.getElementById('page').innerHTML += '<aside id="pictures">content</aside>'; // what I'm now trying to do is to remove this object once USER move its mouse on it document.getElementById('pictures').addEventListener("mousemove",function(event) { setTimeout(function(){ move+=1; // increase the val each second },1e3) console.log('move'+p+' = '+move) // control value if(move>100){ document.getElementById('pictures').style.display = "none"; // OK, it works move=0; // reinit the var } }); } 现在惊喜：第 1 页的控制台 move1 = 0 move1 = 1 ... move1 = 99 move1 = 100 // 'pictures' disappears 第 2 页的控制台 move1 = 41 move2 = 0 ... move1 = 58 move1 = 17 ... move1 = 100 // 'pictures' disappears move2 = 59 第 3 页的控制台 move1 = 15 move2 = 88 move3 = 0 ... move1 = 37 move2 = 100 // 'pictures' disappears move3 = 12 ... 我的 var 'move' 同时获得 3 个值...这怎么可能？您的问题的原因是您每次调用 openPage 函数时都会添加一个事件侦听器。这意味着，如果您单击多个按钮，每个按钮都会有自己的事件侦听器附加到 #pictures 元素。现在，当触发 mousemove 事件时，所有这些侦听器将同时执行，导致 move 变量每秒递增多次。解决此问题的方法是在添加新事件侦听器之前先删除现有的事件侦听器。 let handler; // to hold the event listener function const pictureEl = document.getElementById('pictures'); function openPage(p){ // Remove existing event listener if (handler) { // <-- Check here pictureEl.removeEventListener("mousemove", handler); } handler = function(event) { // ...Rest } }; // Add new event listener pictureEl.addEventListener("mousemove", handler); // ...rest 找到了另一种（最简单的？）方法： var move=0; // placed out of functions function openPage(p){ .... (same as previous) getElementById('pictures').addEventListener("mousemove",outPicts); // change } // put mousemove event in another function: function outPicts(p){ setTimeout(function(){ move+=1; },1e3) console.log('move = '+move) if(move>100){ document.getElementById('pictures').style.display = "none"; // then remove event getElementById('pictures').removeEventListener("mousemove",outPicts); move=0; // reinit the var } } 按预期工作

ASP.NET MVC 项目模板在移动设备上无法调整为 100%

ng-bootstrap 滚动间谍在没有高度的情况下无法工作？

我在我的项目中使用 ng-bootstrap [ngbScrollSpy] 指令，如文档中所述，但它不起作用 - 滚动时活动项目不会改变。我的代码如下：我在我的项目中使用 ng-bootstrap [ngbScrollSpy] 指令，如文档中所述，但它不起作用 - 滚动时活动项目不会改变。我的代码如下： <div> <div class="sticky-top"> <ul class="nav menu-sidebar"> <li > <a [ngbScrollSpyItem]="[spy, 'about']">About</a> </li> <li > <a [ngbScrollSpyItem]="spy" fragment="schedule">Schedule</a> </li> <li > <a [ngbScrollSpyItem]="spy" fragment="hotel">Information about the hotel</a> </li> </ul> </div> <div ngbScrollSpy #spy="ngbScrollSpy" > <section ngbScrollSpyFragment="about"> <h3>About</h3> <p>{{some long long text and content}}</p> </section> <section ngbScrollSpyFragment="schedule"> <h3>Schedule</h3> <p>{{some long long text and content}}</p> </section> <section ngbScrollSpyFragment="hotel"> <h3>Information about the hotel</h3> <p>{{some long long text and content}}</p> </section> </div> </div> 我在这个 stackoverflow 问题中看到，我的问题是我没有向我的 div 提供 height，这是事实。但我的滚动间谍部分遍布整个页面，而不是一个小 div，（导航本身是 sticky-top）。所以我不能给它高度。我知道有替代方法 - 刷新窗口滚动上的滚动间谍，但我没有找到可以帮助我的正确代码。你能解决我的问题吗？为我提供刷新滚动间谍的代码/给我有关高度的提示/帮助我找到另一个相应的元素。非常感谢！附上 stackblitz 演示的链接注意：我使用来自 @ng-bootstrap/ng-bootstrap 的 NgbScrollSpy （我想它是非常相似的库）我做什么：我将所有内容（包括导航）包装在中 <div class="wrapper" ngbScrollSpy #spy="ngbScrollSpy" rootMargin="2px" [threshold]="1.0" > <div class="sticky-top pt-4 pb-4 bg-white"> ..here the navigation... </div> ..here the sections... <section ngbScrollSpyFragment="about"> </section> //the last I use margin-bottom:2rem; <section ngbScrollSpyFragment="hotel" style="margin-bottom:10rem" </section> </div> 见“门槛”。这表明“更改”活动片段应该可见的百分比（1 是 100%）包装类 .wrapper{ height:100%; position: absolute; top:0; } 我使用强制链接的类别 //remove all the class for the link a{ color:black; text-decoration:none; padding:8px 16px; } a.custom-active{ color:white; background-color:royalblue } 以及我使用的每个链接 <a [class.custom-active]="spy.active=='about'">About</a> 嗯，问题是如何“滚动到”。 “链接”应该作为链接使用。第一个是指示“路由器”应该考虑“碎片” 如果我们的组件是独立组件，我们需要使用提供者，provideRouter bootstrapApplication(App, { providers: [ provideRouter([], withInMemoryScrolling({anchorScrolling:'enabled'})), ] }) 然后，我们需要考虑到我们的页面确实没有滚动，div“包装器”是谁拥有滚动。因此，我们订阅 router.events，当事件有“锚点”时，我们滚动“包装器”div constructor(router: Router) { router.events.pipe(filter((e:any) => e.anchor)).subscribe((e: any) => { (document.getElementById('wrapper') as any).scrollTop+= (document.getElementById(e.anchor)?.getBoundingClientRect().top||0) -72; //<--this is the offset }); } 在这个stactblitz中你有一个有效的例子
