使用Jquery AJAX将Javascript变量传递给PHP

Question

I have the following javascript function

function success_callback(p)
    {

        lat = p.coords.latitude.toFixed(2);
        lon = p.coords.longitude.toFixed(2);

    }

Now I want to transfer both the variable to PHP using Jquery AJAX, I am pretty new to Jquery, I am not able to figure out how to do it. I want to transfer the variables to the same PHP file where this JS code resides. Is that possible ?

Answer 1

Yes it is. You could post the variables using the data string. Have a look at the Manual.

$.ajax({
  type: "POST",
  data: "lat="+lat+"&lon="+lon,
  success: function(){
      //callback code
      alert("Done!");
  }
});
