internet-explorer - jQuery 对话框打开导致 IE 中页面不断变长

Question

我在 jQuery 中制作了我的第一个对话框和 AJAX，最后一切都运行良好 - 对话框有几个按钮，取消、保存和生成以从服务器获取新的随机字符串。问题是当我使对话框模式化(使窗口的其余部分变灰)时，然后在 IE 中滚动条出现，有时随着页面不断向下延伸而不断移动。每当打开对话框(它最初未设置为打开)时都会发生这种情况，但并非每次都会发生。我想不出我的代码的任何部分可以做到这一点，因为我什至在任何地方都没有 JS 循环。谷歌搜索这个没有帮助。这看起来像是 IE 与 jQuery 的怪癖，但有什么想法吗？

编辑>感谢您的回复。好的，这是一些代码!这是我的工作演示，它执行相同的操作，并且几乎是 http://jqueryui.com/demos/dialog/#modal-form 中的 jquery UI 模式对话框示例。 ，只是我无法让 IE 在 jquerui.com 示例中采取这种方式。事实上，我仔细检查了一下，它是相同的该死的代码，甚至是“销毁”。有什么不同？

啊，我一直在使用 jQuery UI 1.9m2(里程碑 2 版本)，当前的官方版本是 1.8.10。我下载并尝试了另一个，但它不再这样做了。我想我要去报告正在开发的版本的错误。我需要 1.9 作为工具提示。
