Send login details using js

Question

I would like to write a small script that at startup should fill in some data on the html site that is already specified. So, for example, let's say that the site is a stackoverflow logover page , and I need to fill in my username and password.

Knowing that for the username we have:

<input type="email" name="email" id="email" size="30" maxlength="100" placeholder="[e-mail]">

Password:

<input type="password" name="password" id="password" placeholder="********">

and data:

data = {username:"user", password:"pass"};

our js should be something like below (right?):

document.getElementById("email").value=data.username; 
document.getElementById("password").value=data.password; 

What I really do not understand is how to "send" to the site, and then click the login button. (ajax?) Typically, how to assemble it and make it a running script.

Thanks in advance.
