HTML Style animationDuration用法及代碼示例

HTML DOM中的Style animationDuration屬性用於設置完成一個動畫周期的時間間隔。

用法:

它返回animationDuration屬性。
```
object.style.animationDuration
```

它設置animationDuration屬性。

object.style.animationDuration = "time|initial|inherit"

屬性值：

time:它用於指定動畫將完成一個周期的時間長度。默認值為0，即不顯示動畫。
initial:它用於將樣式animationDuration屬性設置為其默認值。
inherit:它從其父級繼承樣式animationDuration屬性。

供應商前綴：為了使瀏覽器兼容，許多Web開發人員通過使用擴展名來添加browser-specific屬性，這些擴展名包括-webkit-(用於Safari，Google Chrome和Opera)，-ms-(用於Internet Explorer，-moz-(用於Firefox)，-o-(用於舊版本的Opera))等等。如果瀏覽器不支持任何擴展名，它將直接忽略它。
