HTML <iframe> 问题

Question

目前我的情况是我想使用 iframe 在网页中显示一些视频。但是它只显示 1 个视频而不是 10 个。我不确定这里出了什么问题，但是当我将第一个 iframe src="..." 的相同链接放入 第二个 iframe src="..." 视频将显示。仅供参考，我也尝试使用 object 和 embed 但这两种方法似乎都不起作用。这是youtube的问题还是什么？下面是我的代码。这是我的代码。谢谢。 :)

Answer 1

首先，您的第一个关闭</iframe> 标记中有错字，请检查您的代码，您写了</iframe，没有“>”。其次，请注意您如何在第一个 iframe 中使用“嵌入”链接，而在第二个和第三个 iframe 中使用“观看”链接？用嵌入改变它，你很高兴。演示：http://jsfiddle.net/qrqL8tj2/1/

在 .您提供的来源不正确。您的 src 格式应为 > https://www.youtube.com/embed/PQgWnRe9trwcopy 您需要来自 youtube 嵌入选项的链接。
