问题描述

我需要使我的网站的主要内容 980px宽度 500px高度(class =main )仅当鼠标位于滚动div并且高度为1500px 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

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?

小提琴:https://jsfiddle.net/8oj0sge4/3/ full

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";
}
