0x800a1391 - JavaScript runtime error: 'JSON' is undefined in IE 10
提问by Rameez Ahmed Sayad
I'm using IE 10 Compatibility on Windows 8, I'm getting this error while running the WebApp in Debug mode(VS 2012). 0x800a1391 - JavaScript runtime error: 'JSON' is undefined Code below
我在 Windows 8 上使用 IE 10 兼容性，在调试模式（VS 2012）下运行 WebApp 时出现此错误。0x800a1391 - JavaScript 运行时错误：“JSON”未定义代码如下
var data = JSON.stringify(GetUserDetails());
function GetUserDetails() {
var userData = {};
userData.userName = $('#txtUserName').val();
userData.password = $('#txtPassword').val();
return userData;
}
Also , the strange fact is the same code hosted in IIS 8 runs fine in IE 10 Browser. Any inputs?
此外，奇怪的事实是托管在 IIS 8 中的相同代码在 IE 10 浏览器中运行良好。任何输入？

IE8 and up only havethe JSONobject in standardsmode. So you need to make sure the document has a doctype.

I found out for me that it was an IE 10compatibility's intranet setting that was raising this exception for my intranet sites:
我发现它是IE 10兼容性的 Intranet 设置，导致我的 Intranet 站点出现此异常：
"Display the intranet sites in Compatibility View"
“在兼容性视图中显示 Intranet 站点”
To change this flag, or just to simply disable it, display the "Command Bar" in IE 10, then select "Tools" > "Compatibility View Settings" and un-check the option - second from the bottom. Fixed the issue immediately.
要更改此标志，或者只是简单地禁用它，请在 IE 10 中显示“命令栏”，然后选择“工具”>“兼容性视图设置”并取消选中该选项 - 底部第二个。立即修复了该问题。

You need to include json2.js
你需要包含 json2.js
see json2 inclusion
for more details. There are cases where we have to deal with cases where clients use IE7 standards. So our code had to cater to such cases too. Ours being a retail website is accessed by hundreds of clients who use IE7 standards. Including json2 solves this issue
更多细节。在某些情况下，我们必须处理客户端使用 IE7 标准的情况。所以我们的代码也必须迎合这种情况。我们是一个零售网站，有数百名使用 IE7 标准的客户访问。包括 json2 解决了这个问题

I had the same "JavaScript runtime error ...JSON is undefined" running Windows 8 and IE 10, while trying to run an ASP .NET application using Visual Studio 2010 development web server. When I opened the browser, clicked "Alt" to display the menu, then clicked Tools->Compatibility View Settings and unchecked "Display all websites in compatibility view", I stopped getting the error.
我在运行 Windows 8 和 IE 10 时遇到了相同的“JavaScript 运行时错误...JSON 未定义”，同时尝试使用 Visual Studio 2010 开发 Web 服务器运行 ASP .NET 应用程序。当我打开浏览器，单击“Alt”以显示菜单，然后单击“工具”->“兼容性视图设置”并取消选中“在兼容性视图中显示所有网站”时，我不再收到错误消息。
