How do I dynamically change the content in an iframe using jquery?
I was wondering if it is possible to have a site with an iframe and some jquery code that changes the iframe content every 30 seconds. The content is in different webpages.
Something like this:
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script>
$(document).ready(function(){
var array = new array();
array[0] = 'http://webPage1.com';
array[1] = 'http://webPage2.com';
// And so on.
// Do somet开发者_开发百科hing here to change the iframe every 30 second
});
</script>
</head>
<body>
<iframe id="frame"></iframe>
</body>
</html>
<html>
<head>
<script type="text/javascript" src="jquery.js"></script>
<script>
$(document).ready(function(){
var locations = ["http://webPage1.com", "http://webPage2.com"];
var len = locations.length;
var iframe = $('#frame');
var i = 0;
setInterval(function () {
iframe.attr('src', locations[++i % len]);
}, 30000);
});
</script>
</head>
<body>
<iframe id="frame"></iframe>
</body>
</html>
If you just want to change where the iframe points to and not the actual content inside the iframe, you would just need to change the src attribute.
$("#myiframe").attr("src", "newwebpage.html");
var handle = setInterval(changeIframe, 30000);
var sites = ["google.com", "yahoo.com"];
var index = 0;
function changeIframe() {
$('#frame')[0].src = sites[index++];
index = index >= sites.length ? 0 : index;
}
加载中,请稍侯......
