javascript的编码解码

 <script type="text/javascript">

var uri="http://w3schools.com/my test.asp?name=ståle&car=saab";
var uri_encode=encodeURIComponent(uri);
document.write(uri_encode);
document.write("<br />");
document.write(decodeURIComponent(uri_encode));

</script>

The output of the code above will be:

http%3A%2F%2Fw3schools.com%2Fmy%20test.asp%3Fname%3Dst%C3%A5le%26car%3Dsaab
http://w3schools.com/my test.asp?name=ståle&car=saab
