问题
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.
Is this possible? I can't just set it to like 5 seconds, because diffrent computers/tablets load it in diffrent times.
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.
回答1:
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" />
And in the <head> element:
<script type="text/javascript">
function redirect()
{
window.setTimeout(function() {
window.location="../index";
}, 6700);
}
</script>
