所有这些在 jquery 1.4.2 中都可以正常工作

我认为我必须等待升级，但我想我会检查一下是否有其他人有解决方案？

标签： php json jquery jquery-validate jquery-1.5

【解决方案1】：

好的，经过一番搜索，我找到了正确的解决方案，我找到了 jQuery Validate 的 bug report。在报告的底部，validate 的作者提供了一个分叉版本，感谢大家的帮助解决了这个问题

【讨论】：

【解决方案2】：

这很可能是由于 jquery.validate.js 中的错误而发生的。有一个快速（不推荐！）修复 jQuery.ajaxSetup({ jsonp: null, jsonpCallback: null}); - 如果它适合您，请进一步研究不同的选项，there is a discussion 版本 1.5 中的“无效标签”问题。

【讨论】：

到目前为止，如果我取出 jQuery.validate.js，问题也会消失，您给我的修复程序也解决了问题，我现在要查看您链接到的讨论。
您能告诉我使用您的修复程序的缺点是什么吗？
@mcgrailm - 如果您需要使用 jsonp 进行混搭等，这会妨碍您。有关 JSONP 的更多信息：[ibm.com/developerworks/library/wa-aj-jsonp1/]

【解决方案3】：

这是一个错误，已在 1.5.1 中修复。见票http://bugs.jquery.com/ticket/8125，你可以在http://code.jquery.com/jquery-git.js找到带有最新修复的最新jQuery版本

您也可以尝试jQuery.ajaxSetup({ jsonp: null, jsonpCallback: null}); 按照这个帖子JQuery 1.5 and new "Text JSON" datatype

【讨论】：

-git 版本无法解决问题。
