A JQuery function for SVG, to execute 2nd animation as soon as, 1st animation completes?

Question

我应用了动画延迟技术，但是为了实现手写效果animation，我不得不在object相交的地方剪切它，并绘制一条路径并将其转换为剪贴蒙版，例如字母“W”分为4部分并绘制上述不同部分的不同路径，并对其进行动画处理，以提供干净的手写效果，为路径提供笔划宽度，由于字体太复杂，我花了更多时间。

目前，我正在使用动画延迟 CSS function 实现上述 animation。

CSS 代码

#W2-Path {
    animation-delay: .5s
}

#W3-Path {
    animation-delay: 1s
}

#W4-Path {
    animation-delay: 1.5s
}

#O-Path {
    animation-delay: 2s
}

#R1-Path-2 {
    animation-delay: 3.5s
}

#R2-Path-2 {
    animation-delay: 4s
}

#R3-Path-2 {
    animation-delay: 4.5s
}

#L1-Path-2 {
    animation-delay: 5s
}

#L2-Path-2 {
    animation-delay: 5.5s
}

#L3-Path-2 {
    animation-delay: 6s
}

#D1-Path {
    animation-delay: 6.5s
}

#D2-Path {
    animation-delay: 7s
}

I was thinking if there is any other way through which I can start the 2nd animation as the 1st animation completes, and it just keeps going on giving the animation more smoother effect and perfect timing, implementing JQuery?

Answer 1

我只回答后者 W

我已经更改了您拥有的 svg 代码，因为它可以以更简单的方式完成。

您将每一行包装成 2 组。 我只使用线条。 另外，您正在使用style="clip-path: url(#clip-path)"我已将其转换为如下所示的表示属性： clip-path="url(#clip-path)"因为在 javascript 我想将animation-delay设置为线条的内联样式。

另一个变化：我使用stroke-dasharray: 8和stroke-dashoffset: 8因为 8 是字母 W 的线条长度。我知道线条的长度，因为我使用了getTotalLength()方法。

由于字母的线条具有相同的样式，因此该组的stroke和stroke-width仅设置一次。

javascript 选择组中的所有行，然后循环遍历这些行并设置animation-delay:${i*1}s ，其中 i 是第 n 行。 请注意，组中行的顺序是从第一行到第四行，反之亦然，因为您在代码中有它们。

 let Wls = document.querySelector("#W").querySelectorAll("line");//all the lines in the W group Wls.forEach((l,i)=>{ // for each line in the W group // set the style attribute l.setAttribute("style", `animation-delay:${i*1}s`) })

 body { background: white; } svg { width: 90vh; border:solid; } #W line{ stroke-dasharray: 8; stroke-dashoffset: 8; animation: letter-animation 1s linear forwards; } @keyframes letter-animation { 0% { stroke-dashoffset: 8; } 100% { stroke-dashoffset: 0; } }

OP正在评论：

所以当我实际尝试实现它时，我得到了字母“O”，它是一条路径而不是一条线，我尝试了你的方法，它没有出现在路径中，有什么线索可以做些什么呢？

在这种情况下，您必须为路径设置动画。 这次您不需要不同的 css animation 并且由于stroke-dashoffset的最终值为 0，因此您不需要不同的 animation。 但是，您需要计算路径的总长度才能将其用于路径的stroke-dasharray和stroke-dashoffse 。 在这种情况下是 20.4。

 let Wls = document.querySelector("#W").querySelectorAll("line") Wls.forEach((l,i)=>{ l.setAttribute("style", `animation-delay:${i*1}s`) })

 body { background: white; } svg { width: 90vh; border:solid; overflow:visible; } #W line{ stroke-dasharray: 8; stroke-dashoffset: 8; animation: letter-animation 1s linear forwards; } #O path{ stroke-dasharray: 20.4; stroke-dashoffset: 20.4; animation: letter-animation 1s linear forwards; animation-delay:4.5s } @keyframes letter-animation { 100% { stroke-dashoffset: 0; } } @keyframes letter-animation { 100% { stroke-dashoffset: 0; } }
