'JSON' is undefined error in IE only
提问by KevinDeus
I'm making an AJAX call to a WCF service and when I pass in my data i use JSON.stringify()
我正在对 WCF 服务进行 AJAX 调用，当我传入我的数据时，我使用 JSON.stringify()
The call returns and works fine in FF, & Chrome, but not IE8. I get an error: 'JSON' is undefined
调用返回并在 FF 和 Chrome 中正常工作，但不适用于 IE8。我收到一个错误：'JSON' 未定义

I had the issue with IE9. IE9 was rendering my page in "quirks" mode, the solution was simply to add <!DOCTYPE html>. This took me out of "quirks" mode which I'm sure fixed more than just this issue!
我遇到了 IE9 的问题。IE9 以“怪癖”模式呈现我的页面，解决方案只是添加<!DOCTYPE html>. 这让我摆脱了“怪癖”模式，我确信解决的不仅仅是这个问题！

JQuery 2.x is no longer compatible with IE 6-8. JQuery 2.0 beta 2 release notes
JQuery 2.x 不再与 IE 6-8 兼容。JQuery 2.0 beta 2 发行说明
I know the main question is in regard to older versions of JQuery, but this was causing the error for me. I installed JQuery 1.x, which is API-compatible with JQuery 2.x, and added the following detection code:
我知道主要问题是关于旧版本的 JQuery，但这导致了我的错误。我安装了 JQuery 1.x，它与 JQuery 2.x 的 API 兼容，并添加了以下检测代码：
<!--[if lt IE 9]>
<script src="js/jquery-1.11.1.min.js"></script>
<![endif]-->
<!--[if gte IE 9]>
<script src="js/jquery.min.js"></script>
<![endif]-->

In IE open the compatibility view settings and remove the localhost from the listbox for "Websites you have added to Compatibility View". It worked for me.
在 IE 中，打开兼容性视图设置并从“您已添加到兼容性视图的网站”列表框中删除 localhost。它对我有用。
