一个SVG的JQuery函数,可以在第一个动画完成后立即执行第二个动画?

问题描述 投票:0回答:1

我使用了动画-延迟技术,但为了实现手写效果的动画,我必须在对象相交的地方剪断它,并画出一个路径,并将其转换为剪切蒙版,例如字母 "W "分为4个部分,并为上面所说的不同部分画出不同的路径,并对其进行动画处理,使其具有清晰的手写效果,并给路径一个笔画宽度,由于字体太复杂,我花费了更多的时间。

目前我是用animation-delay,CSS函数来实现上述动画。

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
}

我在想有没有其他的方法,可以在第一个动画完成的时候启动第二个动画,然后它就一直在给动画更流畅的效果和完美的时间,实现JQuery?

我只针对后面的W来回答。

我把你的svg代码改了,因为可以用更简单的方法。

你是把每一行都包成两组。我只用了行。而且你用的是 style="clip-path: url(#clip-path)" 我把它转化为一个呈现属性,就像这样。clip-path="url(#clip-path)" 因为在javascript中我想设置 animation-delay 作为行的内联样式。

还有一个变化。我使用了 stroke-dasharray: 8stroke-dashoffset: 8 因为8是字母W的线的长度。getTotalLength() 方法。

strokestroke-width 只为该组设置一次,因为字母的行具有相同的样式。

javascript选择了一个组中的所有行,然后在这些行中循环,并设置该组的 animation-delay:${i*1}s 其中i是第n行。请注意,组中行的顺序是从第1行到第4行,而不是像你的代码中那样反过来。

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;
    }
}

上位者在评论。

所以当我试图实现它的时候,我在字母 "O "上找到了一个路径,而不是一条线,我试了你的方法,它没有出现路径,有什么办法吗?

在这种情况下,你必须对路径进行动画处理。这个时候你不需要不同的css动画,而且由于最终值为 stroke-dashoffset 是0,你不需要一个不同的动画。然而,你需要计算路径的总长度,并将其用于路径的 stroke-dasharraystroke-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;
}

  width: 90vh; 
  border:solid;

}
#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
}
