Can anyone help to do timer in Ajax with php?

[Madhiyalagan]

 <script language="Javascript">
 
        function postRequest(strURL) {
 
    var xmlHttp;
 
        if (window.XMLHttpRequest) { // Mozilla, Safari, ...
 
         var xmlHttp = new XMLHttpRequest();
 
       } else if (window.ActiveXObject) { // IE
 
         var xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
 
       }
 
    xmlHttp.open('POST', strURL, true);
 
    xmlHttp.setRequestHeader('Content-Type', 
         'application/x-www-form-urlencoded');
 
    xmlHttp.onreadystatechange = function() {
 
        if (xmlHttp.readyState == 4) {
 
            updatepage(xmlHttp.responseText);
 
        }
 
    }
 
    xmlHttp.send(strURL);
 
        }
 
 
        function updatepage(str){
 
    document.getElementById("result").innerHTML = 
 
    "<font color='red' size='5'>" + str + "</font>";;
 
        }
 
        function showCurrentTime(){
 
    var rnd = Math.random();
 
    var url="time.php?id="+rnd;
 
    postRequest(url);
 
        }
 
        </script>

Check your line 17 and line 32

in line 17 you are suppose to set the url but in line 32 obviously not the same url. in line 32 you need to set URI.
here is a sample of uri

xmlHttp.send("name=johny&id=10&Title="+escape("Software Developer"));

But there is a little trouble with escape it does not encode "/" and "+".

to do this you can replace "/" with "%2F" and "+" with "%2B". To see more detail about url encode you can follow the link.
