i'm just getting into custom coding in ajax.. fun as hell by the way..

my current problem is i don't know what exactly is getting passed through httprequests. is there a firefox tool that shows what is getting passed?

also... can i put php script into javascript?

i have 2 methods going on .. i wanted to test if php will work in the javascript.. other method is just to grab the id from a hidden value.

Code JavaScript:
 
 
function showprice(str, prodID)
{
 
var str=document.CalculateForm.txtqty.value; 
var prodID=document.CalculateForm.txtprodID.value; 
 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("totalit").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","/getprice.php?q="+str+"pid="+<?= $productID; ?>,true);
xmlhttp.send();
 
 
}
