问题描述

我尝试过以下代码,但可能会在点击时更改,我想在每隔5秒钟后更改iframe内部部分。

i have tried following code but it could change on click, i want to change the iframe inner part after every 5 second interval.

<html>
 <body>
  <iframe id="foo"></iframe>
  <a href="http://www.mydomain.com" target="foo">This page</a>
 </body>
</html>

基本上我的想法就是我会在iframe里面显示这些页面,这5个网页会在之后发生变化每隔5秒钟后另一次。

basically idea is that i have pages which will display inside of iframe, these 5 web pages will change after another after every 5 second interval.

谢谢

<script>
var links = ["http://www.example.com/page","http://www.example.com/anotherpage"];
var i = 0;
var renew = setInterval(function(){
    document.getElementById("foo").src = links[i];        
    if(links.length == i){
        i = 0;
    }
    else i++;
},5000);
</script>
</head>

<body>
<iframe id="foo" src="http://example.com"></iframe>
</body>
</html>

重要提示:并非所有网站都可以在iframe中使用。确保您放在链接数组中的网站允许在iframe中使用。

Important: Not all sites can be used within iframes. Be sure that the website you put in the links array allows to be used inside an iframe.
