❮ jQuery 属性

示例

导致 <div> 元素的动画以较少的帧数运行

定义和用法

jQuery.fx.interval 属性用于更改动画触发速率(以毫秒为单位)。

默认值为 13 毫秒。此属性通常用于修改动画运行的每秒帧数。降低触发速率可以使动画运行更流畅。但是,它可能会导致性能和 CPU 影响。

注意: 为了使对此属性的任何更改生效,任何动画都不应正在运行,或者所有动画都应先停止。

注意: 此属性在支持 requestAnimationFrame 属性的浏览器中无效。


语法

jQuery.fx.interval = 毫秒;

参数 描述
毫秒 必需。指定动画触发速率(以毫秒为单位)。默认为 13 毫秒
