Witam,
mam mały problem. Zrobiłem kod który czyta ceny z innego pliku na ajaxie.
Wygląda to tak:
index.php
[HTML] pobierz, plaintext 
  1. <html>
  2. <head>
  3. <script language="javascript">
  4. function getHTTPObject() {
  5.   var xhr = false;
  6.   if (window.XMLHttpRequest)   {
  7.     xhr = new XMLHttpRequest();
  8.   }
  9.   else if (window.ActiveXObject) {
  10.          try {
  11.            xhr = new ActiveXObject("Msxml2.XMLHTTP");
  12.          }
  13.          catch(e) {
  14.            try {
  15.              xhr = new ActiveXObject("Microsoft.XMLHTTP");
  16.            }
  17.            catch(e) {
  18.              xhr = false;
  19.            }
  20.          }
  21.        }
  22.   return xhr;
  23. }
  24.  
  25. function cena(){
  26. var request = new getHTTPObject();
  27.  
  28. if (request) {
  29. request.onreadystatechange = function() {
  30. if (request.readyState==4) {
  31. if (request.status==200) {
  32. document.getElementById("price").innerHTML=request.responseText;
  33. }}}};
  34. var cc = 1;
  35. var order = document.getElementById("order").value;
  36. var url = "cena.php";
  37. var params = "pro="+order;
  38.  
  39.  
  40. request.open('POST', url, true);
  41. request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  42. request.setRequestHeader("Content-length", params.length);
  43. request.setRequestHeader("Connection", "close");
  44. request.send(params);
  45. }
  46. </script>
  47. </head>
  48. <body>
  49. <h1>Step 1</h1>
  50. <table>
  51. <form action="index.php?step=2" method="post">

I jak wybiorę z select jakąś opcje to dalej widzę kropkę zamiast wartości jaka powinna być.

Testowałem na Google Chrome i IE.
