如何每x秒重新加载一个IFrame？ [英] How to reload an IFrame every x seconds?
问题描述
谢谢。
刷新：x HTTP标头或文档中的HTML元素加载到iframe中：
<< ; meta http-equiv =refreshcontent =x/>
这个元素应该放在文档的< head /> 元素
如果您无法控制加载到框架中的文档或服务器上的文档，您有两种选择：
$ b
- JavaScript。
- 使用上面的
< ; meta />元素，并在该页面中包含一个定位到其他页面的iframe。因此，您将在iframe中包含一个iframe：外部文档 - > iframe（带有元刷新的内部文档） - > iframe（原始iframe目标）
编辑：关于选项＃2，这是PHP中一个体面的通用iframe，它在刷新时间和样式方面提供了一些灵活性。只需使用以下内容调用它即可：
http://www.mydomain.com/genericIframe.php?url=http://my。 domain.com/mypage.htm&refreshTime=60&style=putYourStyleAttribHere
这里是PHP / HTML：
<！DOCTYPE html PUBLIC - // W3C // DTD XHTML 1.0 Transitional // ENhttp://www.w3.org/TR /xhtml1/DTD/xhtml1-transitional.dtd\">
< html xmlns =http://www.w3.org/1999/xhtml>
< head>
< title> Generic Iframe< / title>
< meta http-equiv =refreshcontent =<？php print $ _REQUEST ['refreshTime'];？> />
< / head>
< body>
< iframe src =<？php print $ _REQUEST ['url'];？> style =<？php print $ _REQUEST ['style'];？>>< / iframe>
< / body>
< / html>
Was wondering how I can reload an iframe every x seconds, perferably not using javascript.
Thanks.
解决方案With a
Refresh: xHTTP header or with an HTML element in the document loaded into the iframe:<meta http-equiv="refresh" content="x" />This element should be placed inside of the document's
<head/>element.If you do not have control over the document loaded into the frame or the server that it is served from, you have two options:
- JavaScript.
- Write another HTML page with the above
<meta/>element and include an iframe in that page targeting the other page. So you will have an iframe inside an iframe: outer document -> iframe(inner document with meta-refresh) -> iframe(original iframe target)
EDIT: Regarding option #2, here's a decent generic iframe in PHP that gives some flexibility in terms of refresh time and style. Just call it with something like:
http://www.mydomain.com/genericIframe.php?url=http://my.domain.com/mypage.htm&refreshTime=60&style=putYourStyleAttribHereHere's the PHP/HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Generic Iframe</title> <meta http-equiv="refresh" content="<?php print $_REQUEST['refreshTime']; ?>" /> </head> <body> <iframe src="<?php print $_REQUEST['url']; ?>" style="<?php print $_REQUEST['style']; ?>"></iframe> </body> </html>这篇关于如何每x秒重新加载一个IFrame？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
