每个iframe都会在.NET中调用一些带有大量gridview的网页。我正在使用ASP.NET开发这些页面。我的问题开始了。

我知道iexplorer.exe正在成长，因为我在这些页面中加载了大量数据。它有时会达到400MB。但问题是，即使我关闭iframe，这意味着...... 我制作其中一个iframe src = about：blank并将其设为display = none; 但是，iexplorer.exe的内存大小不会下降。它没有释放内存。我怎样才能让记忆恢复正常？实际上，我已经在IE8中进行了测试。但IE9似乎正在释放内存。我不确定。

修改我将iframe关闭为velow

document.all['iframe' + menuOrder[currentTab]].src = "about:blank";
document.all['iframe'+menuOrder[currentTab]].style.visibility="hidden";

Answer 1

将隐私设置为隐藏不会“关闭”iframe。即使你看不到它，它仍然在消耗资源。您可以降低内存使用量，将iframe正在使用的页面更改为空白页。

即使iframe关闭，也不会释放内存
