ajax xmlrpc,ajax - Create a Wordpress post with xmlrpc and jQuery - Stack Overflow

I have a dynamic page where the user can fill some fields. Those users will all have an account on a WordPress blog. I would like to allow them to directly post the content generated by the webpage to the blog. I don't want to store their password in the server so I want to do this client-side with JQuery.

I have looked both at the standard jQuery.post method and the rpc plugin but I didn't manage to make them work. For example, my latest attempts were something like this:

wprpc = $.rpc('http://blog.wordpress.com/xmlrpc.php', 'xml', callback);

function callback(server) {

answer = server.newPost(0,'user','pass','TestRPC');

alert(answer);

}

and a desperate one:

$.post('http://blogurl.com/xmlrpc.php', { blogid: 0, username: "user", password: "pass", struct: "Test" }, function(data) {alert(data);}, 'xml');

but it silently failed (the callback is not even called).

How would you do this ?
