您没有遗漏任何东西，您在 oembed 插件中发现了一个错误。很好的发现，也许你在质量保证方面有未来的职业:)
看起来 oembed 和 jQuery 都想使用.type，但 jQuery 最终以 oembed 的字符串结尾.type，它想要自己的函数.type。
oembed插件适用于 jQuery-1.3.2，但从 jQuery-1.4.3 开始中断。
您可以从此 jsfiddle 中提取 oembed 插件的功能版本：http: //jsfiddle.net/ambiguous/ZVhUn/1/
此问题已多次报告，但 oembed 作者似乎没有在听。如果需要，这是插件的固定版本：

唯一的变化是我在文件底部var oembed = $.extend(data);用var oembed = $.extend({ }, data);in替换了。this.embedCode
