我需要使我的网站的主要内容 980px宽度和 500px高度(class =main )仅当鼠标位于滚动div并且高度为1500px 且宽度为100%(class =container-scroll),在其他div中,高度为500px。(class =container)
I need to make the main of my site that has 980px width and 500px height (class="main") be fixed only when the mouse is over a scrolling div and has a height of 1500px and a width of 100% (class="container-scroll"), that is inside other div with height of 500px. (class="container")
相当困惑,对吗?
我做了一个小提琴,我差不多了,问题是如果我把主要设置为固定,它将滚动页面,而不仅仅是div内部
I made a fiddle, I'm almost there, the problem is that if I set up the main to fixed, it will scroll with the page , not just inside the div
这是我的小提琴:jsfiddle/8oj0sge4/1/embedded/result/
HTML:
<div id="wrapper"> <div class="container"> <div class="container-scroll"> <div class="main"> </div> </div> </div> </div>CSS:
#wrapper { width: 100%; height: 1500px; border: 1px solid red; padding-top: 380px; } #wrapper .container { border: 1px solid green; width: 100%; height: 500px; overflow: scroll; } #wrapper .container-scroll { height: 1500px; width: 100%; border: 1px solid yellow; } #wrapper .main { width: 980px; height: 500px; background: black; overflow: scroll; /*position: fixed;*/ }推荐答案
如果我理解正确,你希望主div保持在父div的顶部?
If I'm understanding this correctly, you want the main div to stay on the top of the parent div?

所做的更改:
- #wrapper .main :已添加位置:绝对(固定为父级)
- #wrapper .container-scroll :添加 position:relative (确定修复的父级是什么)
- 在主div中添加了一个id(为方便起见)
- #wrapper .main: Added position:absolute ("fixed" to parent)
- #wrapper .container-scroll: Added position: relative (determines what parent to "fix" to)
- Added an id to the main div (for convenience)
JavaScript代码:
JavaScript code:
var main = document.getElementById('main-site'); var maxTop = main.parentNode.scrollHeight-main.offsetHeight; // Make sure we don't go outside the parent main.parentNode.parentNode.onscroll = function() { main.style.top = Math.min(this.scrollTop,maxTop) + "px"; }更多推荐
