gif动画完成后触发javascript [英] javascript trigger when gif animation is done
问题描述
我有一个上面没有重复gif的网站，因此看起来好像正在加载.我想要一个JavaScript脚本，该脚本可以检测gif何时完成动画制作，然后重定向到另一个站点.
I have a site with a not-repeating gif on it, so it looks like it is loading. I would like a javascript script that detects when the gif is done animating, and then redirects to another site.
这可能吗?我不能将其设置为5秒左右，因为不同的计算机/平板电脑会在不同的时间加载它.
Is this possible? I can't just set it to like 5 seconds, because diffrent computers/tablets load it in diffrent times.
如果您希望看到它的实际效果，请继续访问 https://www. frossblock.dk/misc/loading -据我所知，它在计算机上运行良好，但在平板电脑/手机上，它没有足够的时间完成完整的动画.
If you would like to see it in action, then please go ahead and visit https://www.frossblock.dk/misc/loading - It works fine on computers as far as i know, but on tablets/phones it does nt have time enough to complete the full animation.
推荐答案
在加载GIF时启动一个等于GIF持续时间的计时器；
Start a timer equal to the GIF duration when the GIF has loaded;
<img onload="redirect();" style="position:absolute;top:0;bottom:80px;right:0;left:0;margin:auto;" src="../images/loading.gif"" width="150" height="150" />
并在<head>元素中:
<script type="text/javascript">
function redirect()
{
window.setTimeout(function() {
window.location="../index";
}, 6700);
}
</script>
