我正在使用 Microsoft Visual Web Express 2012 for Web 并且一直在通过 Firefox 进行测试。
当我终于让它工作时,我开始尝试 Chrome 和 IE,但在这两种浏览器上,它都会在一个小窗口中报告 500 内部服务器错误。html 加载正常。我相信这是因为我的网站在选项卡小部件中加载了数据库信息。重新检查 Firefox;看起来不错。重新检查 Chrome 和 IE;同样的错误。
现在可能很明显,但是我已经注释掉了 ajax 代码,并且 IE 和 Chrome 没有报告 500 问题。
我不知道如何找到有关此一般错误的更多详细信息。我试过了
<system.webServer>
<httpErrors errorMode="Detailed" />
<asp scriptErrorSentToBrowser="true"/>
</system.webServer>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
在我的 web.config 中,但该窗口仅显示 500。我还尝试取消选中“显示友好的 HTTP 错误消息”和“禁用脚本调试(IE)和(其他)”。我不确定应该发生什么,但 500 消息没有改变。
我确实注意到 Firefox 在从数据库加载时确实显示出奇怪的延迟,但加载后那里的所有数据都很好。
这是有问题的代码。

我听说过 IE 粗鲁的兼容性惊喜,但我不认为这里是这种情况。
编辑:嗯,我找到了一些东西,但我不知道该怎么做。
