动画与Jquery的结果不一致

动画与Jquery的结果不一致,jquery,animation,Jquery,Animation,我有一个用jQuery设计的索引页动画,它的行为并不一致(所有部分都应该以逻辑方式居中)。可在以下网址查看。如果你把它刷新几次,你会发现它在谷歌浏览器中并不总是以同一个位置结束,但在所有其他浏览器中都能正常工作。要在chrome中查看此问题,页面需要刷新几次。任何帮助都将不胜感激,下面列出了.js文件的代码 // JavaScript Document $(document).ready(function() { $(".intro-no-js").css("visibility","hid

问题在于,虽然这些元素在最初运行javascript时确实存在于DOM中,但它们实际上尚未在浏览器中呈现,因此还没有实际的宽度或高度。由于您使用了
outerWidth
outerHeight
这两个选项,在页面加载时错误地返回了0,因此放置处于关闭状态


解决这个问题的一个简单方法是,不要在
$(文档)上调用初始动画。准备好了
,而是在
$(窗口)上。加载
,在渲染元素和下载图像后触发。

我使用的是FF11,动画口吃得很厉害,但在重新加载30页之后,只会有一次定位错误。铬16似乎在50%的时间里都会出现问题。你已经注意到,有人能解决这些问题吗?
