Dieses Mal werde ich Ihnen SVG-Animationen in der Front-End-Entwicklung vorstellen. Was sind die Vorsichtsmaßnahmen bei der Verwendung von SVG-Animationen in der Front-End-Entwicklung? ein Blick.
animateDas animate-Element in SVG kann verwendet werden, um Animationseffekte zu erzielen attributeNameDefinieren Sie den geänderten Elementattributnamen
Wenn attributeType="XML" gilt, wird attributeName als XML-Attribut betrachtet; wenn attributeType="CSS" gilt, wird attributeName als CSS-Attribut betrachtet; wenn attributeType nicht angegeben ist, wird attributeName als verwendet Zuerst ein CSS-Attribut. Wenn es ungültig ist, wird attributeName als XML-Attribut verwendet.
von und bis definieren jeweils den Anfangswert und den Endwert des geänderten Attributs. from kann standardmäßig verwendet werden, was bedeutet, dass der Anfangswert der entsprechende Attributwert des animierten übergeordneten Elements ist. Sie können to durch by ersetzen, um den Änderungsoffset anzugeben. Es kann als to = from + by verstanden werden.
begin definiert die Startzeit der Animation; dur definiert die erforderliche Zeit der Animation; end definiert die Endzeit der Animation. Zeiteinheit h: Stunde; min: Minute; s: Sekunde; Die Standardzeiteinheit ist: s
Wenn fill="freeze", wenn die Animation endet, bleibt der geänderte Elementattributwert in dem Zustand, in dem die Animation endet, wenn fill="remove", Wenn die Animation beendet wird, kehren die geänderten Elementattributwerte in den Zustand zurück, in dem die Animation gestartet wurde. Der Standardwert des Füllattributs ist: entfernen.
<rect x="10" y="10" width="200" height="20" stroke="green" fill="none"> <animate attributeName="width" attributeType="XML" from="20" to="200" begin="0s" dur="3s" fill="freeze" /></rect>
Der Attributname von animateTransform wird als Transformation angegeben, und das Typattribut wird verwendet, um die Attribute anzugeben, die geändert werden müssen, z. B.: Übersetzen, Skalieren, Drehen, SkewX, SkewY usw.
<rect x="10" y="10" width="20" height="20" style="fill: #ff9; stroke: black;"> <animateTransform id="a1" attributeName="transform" attributeType="XML" type="scale" from="1" to="4 2" additive="sum" begin="0s" dur="4s" fill="freeze"></animateTransform> <animateTransform attributeName="transform" attributeType="XML" type="rotate" from="0" to="45" additive="sum" begin="a1.end" dur="4s" fill="freeze"></animateTransform></rect>
animateMotion kann dafür sorgen, dass sich das übergeordnete Element entlang eines angegebenen Pfads bewegt, wie zum Beispiel:
<g> <rect x="0" y="0" width="50" height="30" style="fill: #ccc;"/> <circle cx="40" cy="30" r="10" style="fill: #fff; stroke: black;"/> <circle cx="10" cy="30" r="10" style="fill: #fff; stroke: black;"/> <animateMotion path="M50,125 C 100,25 150,225, 200, 125" dur="4s" fill="freeze"/></g>
