Parse Results for an ID

[treeleaf20]

All,
If I have the following code:
Code:

var http_request = false;
   function makePOSTRequest(url, parameters, str) {
      http_request = false;
      if (window.XMLHttpRequest) { // Mozilla, Safari,...
         http_request = new XMLHttpRequest();
         if (http_request.overrideMimeType) {
         	// set type accordingly to anticipated content type
            //http_request.overrideMimeType('text/xml');
            http_request.overrideMimeType('text/html');
         }
      } else if (window.ActiveXObject) { // IE
         try {
            http_request = new ActiveXObject("Msxml2.XMLHTTP");
         } catch (e) {
            try {
               http_request = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {}
         }
      }
      if (!http_request) {
         alert('Cannot create XMLHTTP instance');
         return false;
      }

      http_request.onreadystatechange = alertContents;
      http_request.open('POST', url, true);
      http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
      http_request.setRequestHeader("Content-length", parameters.length);
      http_request.setRequestHeader("Connection", "close");
      http_request.send(parameters);
   }

   function alertContents() {
      if (http_request.readyState == 4) {
         if (http_request.status == 200) {
            //alert(http_request.responseText);
            result = http_request.responseText;
            document.getElementById('myspan').innerHTML = result;
			window.location.hash = "#picture_id";
  			resizeAll();
         } else {
            alert('There was a problem with the request.');
         }
      }
   }
   
   function getpic(obj) {
	  var poststr = "picture=" + encodeURI( document.getElementById("picture").value );
      makePOSTRequest('getnextpic.php', poststr);
   }

How can I parse:

result = http_request.responseText;

So I can get a picture_id so I can update my hash on this line?

window.location.hash = "#picture_id";

I tried this:

var imgs = document.getElementsByTagName("img");
for ( var d = 0; d < imgs.length; ++d )
    {				
     var img = imgs[d];
     if ( img.className == "showpictureid" )
        {
	      imgid = imgs[d].getAttribute("id");
	      //alert("The image id is" + imgid);
	}
}

But it doesn't work. The PHP code is:

echo "<div style=\"position:relative;\"><img src=\"uploaded_files/$resultsetstory[image_id]\" class=\"showpictureid\" id=\"$resultsetstory[image_id]\" onclick=\"javascript:getpic(this.myform2);\"></div>";

Your javascript pieces are fine, and the code should return the ids. Are you sure about your php script being executed and the results received by the browser?
