Question

我编写了一个简单的Spring MVC请求映射控制器，旨在向我的页面添加分析javascript代码。控制器将脚本代码作为简单字符串返回，该字符串作为IFrame的源添加到页面中。这几乎适用于所有浏览器Chrome，Firefox，IE6 / 7/9，但不适用于IE8。

每当页面点击请求映射时，会出现弹出窗口，表示无法启动应用程序。在弹出的单击详细信息按钮上，将显示以下错误文本 -

不知道IE8看到什么是重复的路由节点（其他浏览器似乎并不在乎），但这是请求映射方法返回的脚本 -

我尝试从控制器方法返回一个空的<script type="text/javascript" ></script> scriplet，但我仍然弹出一个，错误摘要已更改为 -

ERROR SUMMARY
    Below is a summary of the errors, details of these errors are listed later in the log.
    * Activation of http://myhost/getomniturescript?eventType=showCart&user=null resulted in exception. Following failure messages were detected:
        + Exception reading manifest from http://myhost/getomniturescript?eventType=showCart&user=null: the manifest may not be valid or the file could not be opened.
        + Parsing and DOM creation of the manifest resulted in error. Following parsing errors were noticed: 
            -HRESULT:   0x8007001f
             Start line:    0
             Start column:  0
             Host file:     
        + A device attached to the system is not functioning. (Exception from HRESULT: 0x8007001F)

我尝试直接从网络浏览器的地址栏点击控制器，而不是通过页面，结果保持不变。这意味着该错误与IFrame或添加脚本的页面无关。该脚本在开头有一个空行，这意味着第6行第2行的位置是第二个脚本标记的开头。

看起来脚本存在一些问题，使其与IE8不兼容。为什么IE8试图将其作为应用程序打开呢？

我真的很坚持，任何帮助都将不胜感激。

此致

Answer 1

所以这里的问题不在于我在页面上放置的脚本。问题不在于逻辑。我通过JQuery将控制器的调用更改为异步AJAX调用，并且工作正常。
