我的页面足够高，可以垂直滚动。完成加载后，浏览器会自动滚动到cfgrid元素所在页面的底部。它发生在IE，Chrome和Firefox中。
我已将原因缩小到ColdFusion 11服务器添加到页面顶部的JavaScript。如果我在浏览器中禁用脚本，页面不会自动滚动到底部。
将window.scrollTo（0,0）添加到body onload不起作用。无论JS在底部事件之后滚动到底部是什么。我还没有尝试过jQuery的.ready（）;希望有一个解决办法。
有没有其他人看过这个并知道修复或解决方法？

将来，请提供直接代码，以便此处的用户可以正确使用您正在使用的内容。使用CF9，我无法复制行为，但就像你说的那样，你正在使用CF11。
您编写的代码，您继承的代码，或者您从某处复制的代码（如教程）？你确定它是CF生成的javascript导致破坏而不是设计用于聚焦网格的javascript吗？
如果这是你无法追踪的东西，而其他人没有更好的解决方案，这可能会有效。它目前设置为3000（3秒），但较短的时间应该更好（并且不会让用户烦恼。
我会把它放在你的cfgrid之后。
<script>
setTimeout(function(){ window.scrollTo(0,0); }, 3000);
</script>
你也可以找到这个javascript的解决方案。
var scrolled = 0;
window.onscroll = function() {
if (!(scrolled)) {
scrolled = 1;
setTimeout(function(){ window.scrollTo(0,0); }, 300);
}
};
但我只会将它放在您的cfgrid页面中，而不是放在您的网站上。惹恼别人的好方法。

感谢您的建议，@ cfqueryparam。但我发现解决方案是将属性selectOnLoad="false"添加到cfgrid标记。它在CF11中的默认值是＆＃34; true＆＃34;。我不确定CF10，但在CF9中似乎默认为＆＃34; false＆＃34;。
