}

This answer was created before SO's change to more secure policies, I have updated the demo by adding a "s" to http of the src.这个答案是在 SO 更改为更安全的策略之前创建的,我通过向 src 的 http 添加“s”来更新演示。 Keep in mind that any interaction with an iframe is subject to security measures of both the website of the iframe and the website within the iframe.请记住,与 iframe 的任何交互都受 iframe 网站和 iframe 内网站的安全措施的约束。
You can use HTML and you don't need CSS or JS/jQ:您可以使用 HTML,并且不需要 CSS 或 JS/jQ:
<a>
with the href
with the url of desired destination.使用所需目的地的 url 创建一个带有href
的<a>
。target
attribute with the value of the iframe's name
attribute.添加具有 iframe name
属性值的target
属性。BTW, Google and Facebook busts iframes, so the demonstrations have different sites.顺便说一句,谷歌和 Facebook 破坏了 iframe,所以演示有不同的网站。
<!DOCTYPE html> <html> <head> <style> iframe { width: 97vw; height: 65vh; } </style> </head> <body> <fieldset> <button><a href='https://plainjs.com' target='ifrm1'>PlainJS</a> </button> </fieldset> <iframe name='ifrm1' src='about:blank'></iframe> </body> </html>
