我有一个包含iFrame的页面,其源代码是ashx页面。处理程序通过查询字符串接受3个参数,并生成包含表的text / html响应。当表格获得> 1700行时,它会崩溃IE8浏览器。浏览器冻结并返回空引用错误。
如果我将正在渲染的html放在页面上的DIV中,它在IE8中渲染得很好。有什么建议吗?

崩溃是由名为SmartScreen的IE8功能引起的。它可以防止用户导航到已知的恶意软件和网络钓鱼站点。它也是一种非预期的功能,可以防止网站在渲染后删除大量数据。一旦关闭此功能,崩溃就会完全消失。

[更新]从您的评论中,我不认为问题是大表。因此,这个答案不适用,但我会离开它,因为看起来这个问题在SO上出现了很多次。
尝试“兼容性视图”,同样的问题?
尝试缩小页面大小。例如,

如果我将正在渲染的html放在页面上的DIV中,它在IE8中渲染得很好。有什么建议吗?
ashx处理程序是渲染完整的html页面还是只渲染表格片段?
确保页面是带有html,body标签的有效html。
表格也冻结了大多数浏览器的布局过程。您是否尝试过使用div标签来查看它是否会崩溃IE 8
