    post instead of get

    Want to get the example below to work with open("POST",url,true) instead of open("GET",url,true).
    When I try that, the program doesn't seem to do anything when I click the buttons. The last try is commented out.
    How do you get it to work with POST ?

    Code:
    <html>
       <head>
          <title>
          </title>
          <script language="javascript" type="text/javascript">
          <!--
             function f(fn,dv)
             {
                var req=false;
                if (window.XMLHttpRequest)
                {
                   req=new XMLHttpRequest();
                }
                else
                {
                   if (window.ActiveXObject)
                   {
                      req=new ActiveXObject("Microsoft.XMLHTTP");
                   }
                };
                if (req)
                {
                   var fn1=fn+"?t="+Math.random();
                   req.open("GET",fn1,true);
                   //req.open("POST",fn1,true);
                   //req.setRequestHeader("Content-type","application/x-www-form-urlencoded");
                   req.onreadystatechange=function()
                                          {
                                             if (req.readyState==4 && req.status==200)
                                             {
                                                //var rt2=req.responseText;
                                                var rt2="<img src="+req.responseText+">";
                                                document.getElementById(dv).innerHTML=rt2;
                                                delete req;
                                                req=null;
                                             }
                                          };
                   req.send(null);
                   //req.send();
                }
                else
                {
                   alert('No req.');
                   return false;
                };
             }
          -->
          </script>
       </head>
       <body>
          <div id="dv1">
             <form>
                <input type="button" value="*" onclick="f('aa.txt','dv2');">
                <input type="submit" value="*">
             </form>
          </div>
          <div id="dv2">
          </div>
       </body>
    </html>

    your req.send has to have the parameters passed inside it.

    Code:
    req.open('POST", fn, true);
    req.setRequestHeader('Content-type','application/x-www-form-urlencoded');
    req.onreadystatechange=function() {
    	if (req.readyState==4 && req.status==200) {
    		document.getElementById(dv).innerHTML = '<img src='+req.responseText+'>';
    		delete req;
    		req = null;
    	}
    };
    req.send('t=' + Math.random());
    You put it in the send, not in the URL.

    Oh, and small tip, TRY to avoid making 'variables for nothing'.

    Tried that and other things but no luck. Req.readyState went to 4 and req.status was 405.

    405? Method not allowed?

    Can you make a flat non-ajax method="post" form and have it work? Could be POST is blocked... could also be your server doesn't allow post and AJAX.

    Though you're passing to a txt file, which makes no sense. "aa.txt" is not something you should have as a URL to a form handler. Apache could be blocking it. What is "aa.txt"? If you change it to a PHP file does it work?

    The text file extension was the problem.
    The example works with post method now.
    Thank you very much.
