问题 When trying to find out how much a web page has been scrolled from the top, which of these should one use: document.body.scrollTop , document.documentElement.scrollTop , window.pageYOffset , window.scrollY Which one(s) would I choose in these 2 separate scenarios: a) If I wanted maximum compatibility (across the main browsers used currently)? b) If I wanted code that was most standards compliant/future-proof/strict-mode-compatible (but didn't care about supporting old/non-standard browsers)?

scrollTo gets overridden when using jQuery Mobile

阅读更多关于 scrollTo gets overridden when using jQuery Mobile

问题 I am creating a mobile web app with jQuery Mobile and would like to hide the search bar above the visible area. So the user would need to pull the page down to see the search bar. I'm thinking the best way to do that is to define the search bar as usual then on page load manually set the scroll position, say down 55px. Here's my code: $(document).ready( function() { $("html,body").scrollTop(55); } The problem is, I can see upon refreshing the page it is hidden from view, but once it has fully

解决移动端滚动穿透问题（兼容ios，android）

阅读更多关于解决移动端滚动穿透问题（兼容ios，android）

解决问题。网上找了一圈大多都是; overflow: hidden 页面有弹出层时将overflow: hidden样式添加到 html 上，禁用 html 和 body 的滚动条，但是这个方案移动端根本无用！！！！，pc端也有两个缺点； 1.由于 html 和 body的滚动条都被禁用，弹出层后页面的滚动位置会丢失，需要用 js 来还原。 2.页面的背景还是能够有滚的动的效果。方案二：touchmove + preventDefault modal.addEventListener('touchmove', function(e) { e.preventDefault(); }, false); 如果是vue项目在弹层最外层父容器添加属性： @touchmove.prevent 次方案适用于你的弹层内部不需要滚动。终极方案： position: fixed 如果只是加fixed，滚动条的位置同样会丢失。所以如果需要保持滚动条的位置需要用 js 保存滚动条位置关闭的时候还原滚动位置。 <script type="text/javascript"> //解决遮罩层滚动穿透问题，分别在遮罩层弹出后和关闭前调用 const ModalHelper = ( (bodyCls) =>{ let scrollTop; return { afterOpen: function () {

一，使用 scrollbar 滚动条（使用锚点的方式） <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>点击回到页面顶端</title> </head> <body style="height:2000px;"> <button id="test" style="position:fixed;right:0;bottom:0">回到顶部</button> <script> test.onclick = function(){ document.body.scrollTop = document.documentElement.scrollTop = 0; } </script> </body> </html> 二，scrollTop:scrollTop属性表示被隐藏在内容区域上方的像素数。元素未滚动时，scrollTop的值为0，如果元素被垂直滚动了，scrollTop的值大于0，且表示元素上方不可见内容的像素宽度由于scrollTop是可写的，可以利用scrollTop来实现回到顶部的功能 <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>点击回到页面顶端</title> </head>

问题 Got a little bit of a problem with getting my jquery accordion to do what I want. I always want the tab that is being clicked to be scrolled to a fixed amount of pixels from the top of the page, and I kinda got it working. But whenever the active tab is above the tab being clicked and if the page already is scrolled down a bit, the top and parts of the content of the clicked tab is scrolled up past the top of the page. This is what i got: $(function() { $("#accordion").accordion({ autoHeight:
