我想知道如果有人知道如何使用jquery创建一条对角线，并对其进行动画处理，这样当它出现时，它的绘制而不是仅仅出现。

I was wondering if anyone knows how to create a diagonal line using jquery and animate it so that when it appears its drawn on rather than just appears?

推荐答案

你可以用纯CSS实现：

You could actually do it with pure CSS:

HTML ：

<div class='box'></div>

CSS ：

.box { overflow: hidden; outline: dotted 1px; width: 8.09em; height: 5.88em; background: linear-gradient(36deg, transparent 49.5%, black 49.5%, black 50.5%, transparent 50.5%) no-repeat -8.09em -5.88em; background-size: 100% 100%; animation: drawDiag 2s linear forwards; } @keyframes drawDiag { to { background-position: 0 0; } }

Circle

HTML ：

<div class='circle'> <div class='cover'></div> </div>

CSS ：

.circle { overflow: hidden; position: relative; width: 10em; height: 10em; } .circle:before { position: absolute; width: inherit; height: inherit; border-radius: 50%; box-shadow: inset 0 0 0 1px black; content: ''; } .cover { position: absolute; margin: 0 -50%; width: 200%; height: inherit; transform-origin: 50% 0; background: white; animation: revealCircle 5s linear forwards; } @keyframes revealCircle { to { transform: rotate(180deg); } }
