javascript - How to refresh <iframe> using Ajax? -

i refresh link http://radiojoven.6te.net/capas.php using ajax. i've been trying, no avail. here's have far:

<script> function checkrequest() {     var interval = settimeout(function () {         $.ajax({             url: "http://radiojoven.6te.net/capas.php",             type: "post",             datatype: "html"         })             .done(function (msg) {             $("capas").html(msg);         })             .always(function () {             checkrequest();         });     }, 20000); } </script> 

the iframe plan update:

<div id="capas"><iframe src="http://radiojoven.6te.net/capas.php"      width="1000px" height="300px" border="0" marginwidth="0"      marginheight="0" hspace="0" vspace="0" frameborder="0" scrolling="no"></iframe></div> 

if can me in work, grateful.

already thank you.

i recommend rid of iframe , use ajax.

the reason why never updates capas div not referenced correctly.

you need $("#capas").html(msg); // note # refer id of element.

as additional note, doesn't seem posting data server, therefore may better of using http get rather http post.
