How can you set the Content-Type header to "application/x-www-form-urlencoded; charset=UTF-8" using JavaScript?
I need to do this so I can view a form with french characters without generating errors.
Thanks
回答1:
Headers are set by the server delivering the content-type as part of the HTTP message. By the time it's in the browser and running the javascript it's too late. Do you have access to the server-side code? Why not set the content type to utf-8 in there? You can also do it as part of the meta tag in the head.
回答2:
You can add a meta tag into the head of the page, or send the header server-side.
example,
<meta http-equiv="Content-type" content="application/x-www-form-urlencoded; charset=UTF-8"/>
on the server-side, say PHP:
<?php
header( 'Content-type: application/x-www-form-urlencoded; charset=UTF-8' );
?>
that's it!

The content type is set by the server before it sends the HTML to the browser. You can't modify it with JavaScript.
