smokehut Posted May 18, 2013 Share Posted May 18, 2013 What I'm trying to do in a nutshell is create a full 5 step interaction between a user and a "host" on my site, without the need for one refresh, as I designed my website for fast-linking with #tag for selecting pages. so if a refresh occurs it's back to the home page . Basically, what I've got. ajax.js // Customise those settings var seconds = 5; var divid = "timediv"; var url = "boo.php"; //////////////////////////////// // // Refreshing the DIV // //////////////////////////////// function refreshdiv(){ // The XMLHttpRequest object var xmlHttp; try{ xmlHttp=new XMLHttpRequest(); // Firefox, Opera 8.0+, Safari } catch (e){ try{ xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); // Internet Explorer } catch (e){ try{ xmlHttp=new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ alert("Your browser does not support AJAX."); return false; } } } // Timestamp for preventing IE caching the GET request fetch_unix_timestamp = function() { return parseInt(new Date().getTime().toString().substring(0, 10)) } var timestamp = fetch_unix_timestamp(); var nocacheurl = url+"?t="+timestamp; // The code... xmlHttp.onreadystatechange=function(){ if(xmlHttp.readyState==4){ document.getElementById(divid).innerHTML=xmlHttp.responseText; setTimeout('refreshdiv()',seconds*1000); } } xmlHttp.open("GET",nocacheurl,true); xmlHttp.send(null); } // Start the refreshing process var seconds; window.onload = function startrefresh(){ setTimeout('refreshdiv()',seconds*1000); } Then, boo.php <? /*$query = "SELECT * FROM deposits WHERE user = ? AND completed = 0"; $stmt = $db->prepare($query); $stmt->bindValue(1, $user_data['username']); $stmt->execute(); $fetch = $stmt->fetch(PDO::FETCH_ASSOC);*/ // Format time output $str = "It is %a on %b %d, %Y, %X - Time zone: %Z"; // Echo results echo(gmstrftime($str,time())); ?> ^ Above is what I'm trying to achieve, but I cannot even get it to echo the time in my other php form that requires the script. <script src="ajax.js"></script> <strong>This is the current date and time (updates every 5 seconds):</strong> <script type="text/javascript"><!-- refreshdiv(); // --></script> <div id="timediv"></div> Can anyone point a beginner in the right direction?

Muddy_Funster Posted May 20, 2013 Share Posted May 20, 2013 I'd like to point you to jquery. as a beginner your would be better off starting to learn that than oldschool "raw" javascript - especially for ajax. another thing - you seem to have commented out the part of the script that actually calls the function....
