Backbone sending parameters over AJAX to server

Hey, I'm very new to backbone, and I've read a little bit of the documentation but I didn't find something appropriate. I would like to use backbone to send some data to the server using AJAX communication. Does backbone have some kind of shortc开发者_JAVA百科ut to do this? For now my simple example consist of a HTML page with an input for username and one for the password. On clicking the button I fire this function:

    //handling the button event on the login form
    function loginPressed(){
        var username = document.getElementById("username").value;
        var password = document.getElementById("password").value;

        loginModel.username = username;
        loginModel.password = password;


    }

The login model is just a model I've created with backbone:

//creating a backbone model to handle login
var loginModel = new Backbone.Model({
        username: "",
        password: "", 
    });

Do you think I can do AJAX request to my server with this?

Thanks, Masiar

P.S. My serverside is node.js

Your model is not defined properly:

var LoginModel = Backbone.Model.extend({
    url: "/your/login/url"
});
...

function loginPressed(){
  var login = new LoginModel
  login.save({
    username: document.getElementById("username").value,
    password: document.getElementById("password").value
  },{
    /*any other jquery ajax options including callbacks*/
  });
}

There are some reasons you should not do login with ajax calls but you'll learn them soon enough :)
