copied!<p>Ok, AJAX has been around since donkey's years, really. But since you're not familiar with JS, here's a little copy-paste function you could use:</p> <pre><code>function ajax(url,method,data) { var xhr;//ajax object data = data || {};//default ajax request method = method || 'POST'; url = url || 'default/url/ajax'; try {//normal browsers ret = new XMLHttpRequest(); } catch (error) {//older IE browsers, including dead IE6 try { ret= new ActiveXObject('Msxml2.XMLHTTP'); } catch(error) { try { ret= new ActiveXObject('Microsoft.XMLHTTP'); } catch(error) { throw new Error('no Ajax support?'); } } } if (typeof ret !== 'object') {//if fails (almost impossible) throw new Error('No Ajax, FFS'); } ret.open(method, url, true);//open ajax connection ret.setRequestHeader('X-Requested-With', 'XMLHttpRequest'); ret.setRequestHeader('Content-type', 'application/x-www-form-urlencode'); ret.onreadystatechange = function() { if (this.readyState === 4 && this.status === 200) { var response = this.responseText; //code you want to see executed when the call was successful } }; return ret.send(data); } </code></pre> <p>Usage:</p> <pre><code>ajax('your/ajax/url','POST','id=12'); </code></pre> <p>This will send an ajax request back to the server, with a POST parameter <code>id</code>, value <code>12</code>... play around with that. A few things that can be useful: <a href="http://json.org" rel="noreferrer">JSON</a>, and -though I'm not a big fan- <a href="http://jquery.com" rel="noreferrer">jQuery</a>, it has a ready built-in <code>$.ajax</code> method, just pass an object literal and you're good to go. </p> <p>Feel free to edit this function as you please</p>
