GIF动画不玩刷新 [英] gif animation not playing on refresh

问题描述

我第一次查看页面用.gif动画它起着罚款页面加载（持续约2秒）。

First time I view the page with an animated .gif it plays fine on page load (lasts about 2 secs).

在刷新（F5），将.gif文件不再戏剧和只显示​​GIF动画的最后一帧。

On refresh (F5), the .gif no longer plays and only the last frame of gif animation is shown.

有什么我能做的做，以确保它起着每次？

Is there anything I can do do to make sure it plays everytime?

推荐答案

奇怪的行为，这是影响到每一个浏览器..结果
我通常用这个脚本（它使用jQuery）

Strange behavior that's affects every browser..
I usually refresh it manually with this script (it uses jQuery)

<img id="gif_animata" src="picturePath.gif">
<script type="text/javascript">
    var gifSource = $('#gif_animata').attr('src'); //get the source in the var
    $('#gif_animata').attr('src', ""); //erase the source     
    $('#gif_animata').attr('src', gifSource+"?"+new Date().getTime()); //add the date to the source of the image... :-) 
</script>

这将刷新图像添加当前日期的src，所以浏览器会重新加载它，以为这是一个新的形象。

This will refresh the src of the image adding the current date, so the browser will re-load it, thinking that's a new image.

否则在PHP的方式（我preFER这一个）：

Otherwise in PHP way (I prefer this one):

<img src="picturePath.gif?<?php echo date("Ymdgis");?>" />

//for the browser it will seems that's a new picture!
<img src="picturePath.gif?2012092011207">
