我想为SVG动画循环的每次迭代添加一个延迟。这是一个简单的例子。
<svg xmlns="http://www.w3.org/2000/svg" width="100px" height="100px">
<circle cx="50" cy="50" r="15" fill="blue">
<animate id="op" attributeType="CSS" attributeName="opacity"
from="1" to="0" dur="3s" repeatCount="indefinite" />
</circle>
</svg>
使用begin
只会延迟第一次迭代,那么有没有办法延迟每次迭代?

您可以将SMIL动画元素的end
事件添加到begin
属性。
此外,您可以添加多个值,以;
分隔为此begin
属性:
<svg xmlns="http://www.w3.org/2000/svg" width="300px" height="100px">
<circle cx="50" cy="50" r="15" fill="blue">
<animate id="op" attributeType="CSS" attributeName="opacity"
from="1" to="0" dur="3s" begin="3s;op.end+3s" />
</circle>
</svg>

定义虚拟循环并设置相对开始时间。看到 How to make SVG Loop Animation?
<svg xmlns="http://www.w3.org/2000/svg" width="300px" height="200px">
<rect>
<animate id="o1" begin="0;o1.end" dur="10s"
attributeName="visibility" from="hide" to="hide"/>
</rect>
<circle fill="orange" cx="-50" cy="100" r="20">
<animate begin="o1.begin"
attributeName="cx" from="250" to="50" dur="5.05s"/>
</circle>
<circle fill="blue" cx="150" cy="100" r="50" />
<circle fill="orange" cx="-50" cy="100" r="20">
<animate begin="o1.begin+5s"
attributeName="cx" from="50" to="250" dur="5.05s"/>
</circle>
</svg>

我认为您正在寻找的是svg的加法/累积属性。这是我从css tricks
获得的一个例子
svg {
border: 3px solid #eee;
display: block;
margin: 1em auto;
}
&#13;
<svg width="500" height="100">
<circle id="orange-circle" r="30" cx="50" cy="50" fill="orange" />
<animate xlink:href="#orange-circle" attributeName="cx" from="0" to="100" additive="sum" repeatCount="3" calcMode="spline" keyTimes="0;1" keySplines=".42 0 1 1" dur="1s" begin="click" fill="freeze" />
</svg>
&#13;
事实上,这是一个更好的例子(同源)
svg {
border: 3px solid #eee;
display: block;
margin: 1em auto;
}
&#13;
<svg width="500" height="150">
<style>
rect {
-moz-transform-origin: 75px 75px;
transform-origin: 50% 50%;
}
</style>
<rect id="deepPink-rectangle" width="50" height="50" x="50" y="50" fill="deepPink" />
<animateTransform
xlink:href="#deepPink-rectangle"
attributeName="transform"
attributeType="XML"
type="rotate"
from="0 75 75"
to="360 75 75"
dur="2s"
begin="0s; 5s; 9s; 17s;"
end="2s; 8s; 15s; 25s;"
fill="freeze"
restart="whenNotActive"
/>
</svg>

这是Danjiro Daiwa的示例的更详细版本,其中没有隐藏的矩形来同步动画,并且没有使用opacity="0"
来设置可见圈之外的橙色圆圈来隐藏它们。有四个动画同时运行,a1 / a2进行移动,o1 / o2在橙色的doppelganger圆在蓝色圆的后面/上方移动时隐藏它们,r1-r4更改半径r
和f1-f4更改fill
的颜色。
<svg xmlns="http://www.w3.org/2000/svg" width="300px" height="200px">
<circle fill="#f70" cx="0" cy="100" r="20" opacity="0">
