JS和PHP - 从js发出信号后加载php数据而不发送回发

Question

Alright so basically I have a flash login, which I handled to work with JS using ExternalInterface. I want the php to load only when the user has logged in, how is it possible to do this without sending a new postback (reloading the page)?

What I basically want is: the JS already appears once the user has logged in. I want it once clicked to execute a MySql query, get the data and show the user without reloading the page.

I know that's AJAX but I really don't know how to do it - I'm not familiar with php, I also don't know how I can run the php when a function is called in JS.

Best regards, iMix

You can use jquery, it would be a quick and practical solution.

function login(){
  $.ajax({
    type: "POST",
    url: "your_login_script.php",
    data: { username: "thatuser", password: "thatpwd" }
  }).done(function( result ) {
    alert(result);
  });
}
