SVG路径动画从单击按钮开始 [英] SVG path animation to begin on click of a button
问题描述
我有一个SVG路径动画,此动画目前处于无限循环中。我希望动画在单击事件触发之前是不可见的,然后一旦动画完成(一次,不是无限次),该按钮将不再起作用。
I have an SVG path animation that at the moment is on an infinite loop. I'd like the animation to be invisible until it is triggered by a click event then once the animation is complete (one time, not infinite) the button should no longer work.
我添加了一个测试按钮,但是在页面加载后,动画似乎仍然可以播放,并且按钮对此没有任何作用。
I've added a test button but the animation still seems to play as soon as the page is loaded and the button has no effect on it.
$("#button").click(function() {
$('.dashed').toggleClass('path');
});
.dashed{
stroke-dasharray: 10;
}
.path {
stroke-dasharray: 1000;
stroke-dashoffset: 1000;
animation: dash 5s linear infinite;
}
@keyframes dash {
from {
stroke-dashoffset: 1000;
}
to {
stroke-dashoffset: 0;
}
}

推荐答案
a)清空类。路径
,但保持在该位置:
a) empty the class .path
but keep it there:
.path { }
b)将您从 .path
中删除的动画属性添加到新的CSS类中
b) add the animation properties you removed from the .path
into a new css class with replacing 'infinite' from the animation property to '1'.
.path-animation {
stroke-dasharray: 1000;
stroke-dashoffset: 1000;
animation: dash 5s linear 1;
}
c)使用以下jquery实现所需的结果:
c) Use the following jquery to achieve the results you require:
$("#button").click(function() {
$('.path').attr('class', 'path path-animation');
//5 secs delay to complete the animation before removing it and disabling the button.
setTimeout(function() {
$('.path').attr('class', 'path');
$("#button").attr("disabled","disabled");
}, 5000);
});
