SVG路径动画开始点击一个按钮

Question

我有一个SVG路径动画，目前在一个无限循环。我希望动画在被点击事件触发之前是不可见的，然后一旦动画完成（一次，而不是无限），该按钮应该不再起作用。

我已经添加了一个测试按钮，但动画似乎在页面加载后仍然播放，并且按钮对它没有影响。

$("#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; 
 
    } 
 
}

<input type="button" id="button" value="Animate" />

Answer 1

一）清空类.path但它保留下来：

.path { } 

b）添加动画属性你将.path从动画属性中的'infinite'替换为'1'，将其从.path中移除为新的css类。

.path-animation { 
    stroke-dasharray: 1000; 
    stroke-dashoffset: 1000; 
    animation: dash 5s linear 1; 
} 

c）用下面的jQuery来实现你需要的信息：

$("#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); 
});

Answer 2

你需要这些小的变化做你的代码：

1）首先除去从现有<path class="path"你的第一个<path>元素。你想按钮添加这个稍后onclick

2）改变你的动画迭代计数从你的animation: dash 5s linear infinite; - '无限'在这里说迭代动画无限的时间。改变，要animation: dash 5s linear 1;

.path { 
    stroke-dasharray: 1000; 
    stroke-dashoffset: 1000; 
    animation: dash 5s linear 1; 
} 

3）然后以第一次点击后禁用按钮，你可以

$('#button').on('click', function() { 
    $('.dashed').addClass('path'); 
    $(this).prop('disabled', true); 
}); 

简单..让我知道，如果你面对任何问题。

检查这个..它应该帮助...

禁用按钮ü可以使用此代码

$("#button").click(function() { 
      $('.path').css("animation"," dash 5s linear"); 
      $(this).attr("disabled","disabled"); 
     });
