[web2py] Put location of a Raphael element in database

[Richard]

Hi,

I am using Raphael for drawing diagrams and want to store de location of 
the elements in the database.

Do I need $.ajax or can I stick to ajax helper?

View:
    var up = function () {
        this.attr({opacity: 1.0});
        var locx = this.attr("x");
        ajax('new_post', ['locx'], 'resp');
    };

Controller :
    def new_post():
          db.post.insert(your_message=request.vars.locx)

Any hint would be welcome
Richard
