Javascript array for AJAX POST send


Here is the deal... I need to make an AJAX save script. I have a whole system built on php and every action needs a refresh... I'm trying to minimize the refresh count by using AJAX ... I can't seem to find a way how to send a WYSIWYG editor output without loss to the PHP script...

if (window.XMLHttpRequest){ xmlhttp=new XMLHttpRequest(); } else{ xmlhttp=new ActiveXObject('Microsoft.XMLHTTP'); } function save(){ xmlhttp.open('POST','action.php',true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", document.getElementById('output').value.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.send(document.getElementById('output').value); xmlhttp.onreadystatechange = function(){ if(xmlhttp.readyState == 4 && xmlhttp.status==200){ $('#ajaxresult').css('opacity', 0.1); $('#ajaxresult').stopAll().pause(1000).fadeTo(400,1); $('#ajaxresult').stopAll().pause(3000).fadeTo(400,0, function(){$(this).hide();}); document.getElementById('ajaxresult').innerHTML=xmlhttp.responseText; } } }

While this script works fine I can't seem to find the way what kind of array to give the send option... what is the syntax or is there something I don't know?

BTW I'm a beginner in JS...


I'd look into using jQuery and it's Ajax library:

<a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow">http://api.jquery.com/jQuery.ajax/</a>

Instead of doing all that you'd simply do:

$.post({url: 'action.php',data: output,success: function() { /* do something here */ }});


create <strong>custom parameter</strong> in the javascript code like below:

var jspNameParam = "content="+escape(document.getElementById('output').value); function myFunction() { if (xmlhttp) { xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4) { /* want to accsess some data written from action.php */ } }; xmlhttp.open("POST", "action.php", true); xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); xmlhttp.send(jspNameParam); } }

Now in action.php you will get whole content with the parameter name <strong>content</strong>.
