我如何使Iframe每5秒进入一个随机页面 [英] How Do I make an Iframe go to a random page every 5 seconds

问题描述

我需要一个iframe的帮助。

到目前为止，我已经设置了这个代码

然而，我不想要按钮。我希望iframe按照每五秒钟的网页列表顺序重定向，因为：

在它旁边，我有一个幻灯片，当它的徽标出现时，我希望帧重定向到

例子：

< blockquote>

Facebook logo> href =/ facebook

[5秒钟后]

Vite logo> href =/ vite

[5秒后]

MULTI徽标> href =/ multi

感谢堆

解决方案

你可以尝试这样的事情。注意：您使用的网站必须包含正确的iframe和原始标题（或从与父网站相同的域中提供）才能显示在您的iframe中

  // iframe的循环访问网站的网址= [https://wikipedia.org，https://stackoverflow.com ，https://stackoverflow.com/questions/44497495/how-do-i-make-an-iframe-go-to-a-random-page-every-5-secounds#]，//可变变量iframe节点的参考帧，//以毫秒为单位显示每个网站的时间INCLUDE（）{currentSlide =（currentSlide + 1）％websites.length; iframe.src = websites [currentSlide];} //等待文档loadwindow.onload = function（）{//获取iframe引用iframe = document.getElementById（slides）; //使用setInterval设置切换幻灯片的重复任务setInterval（switchSlides，INTERVAL）}  

 < iframe id =slidesheight =300pxwidth =100％name =iframe_a>< / iframe>  

I need help with an iframe.

So far, I have this code set up

<iframe height="300px" width="100%" src="/vite" name="iframe_a"></iframe>

<button><a href="/multi" target="iframe_a">MULTI</a></button>
<button><a href="/facebook" target="iframe_a">Facebook</a></button>

However, I don't want the buttons. I want the iframe to redirect in order of a list of web pages every five seconds because:
Next to it, I have a slideshow, and when its logo appears, I would like the frame to redirect to the page of which the logo is indicating.

Example:

Facebook logo > href="/facebook"
[5 seconds later]
Vite logo > href="/vite"
[5 seconds later]
MULTI logo > href="/multi"

I already have the slideshow setup, just asking for the frame.

Thanks heaps

解决方案

You can try something like this. Note: The websites you use must include the correct iframe and origin headers (or be served from the same domain as the parent site) to display inside your iframe

//Array of URLs for the iframe to cycle through
var websites=["https://wikipedia.org","https://stackoverflow.com","https://stackoverflow.com/questions/44497495/how-do-i-make-an-iframe-go-to-a-random-page-every-5-secounds#"], 
//Variable to hold the iframe node reference
iframe, 
//Time to show each website in milliseconds
INTERVAL=5000, 
//Variable to keep track of currentSlide being shown
currentSlide=-1;

//Method to update the SRC attribute of iframe
function switchSlides(){
  currentSlide = (currentSlide+1)%websites.length;
  iframe.src = websites[currentSlide];
}

//Wait for document to load
window.onload=function(){
  //Get iframe reference
  iframe = document.getElementById("slides");
  //Use setInterval to set up repeating task of switching slides
  setInterval(switchSlides,INTERVAL)
}

<iframe id="slides" height="300px" width="100%" name="iframe_a"></iframe>
