<p>这个属性可以设置动画每秒运行帧数。默认是13毫秒。该属性值越小，在速度较快的浏览器中（例如，Chrome），动画执行的越流畅，但是会影响程序的性能并且占用更多的 CPU 资源。</p>
|
||
<p>由于jQuery中，该属性是全局性的，因此在没有动画正在运行或停止所有动画时，此属性的变化才能生效。</p>
|
||
<p><del><strong>注意:</strong><code>jQuery.fx.interval</code>当前在支持<code>requestAnimationFrame</code>属性的浏览器中没有效果，如谷歌Chrome浏览器11。此问题会在今后发布的版本中得以解决。</del></p>
