  1. POAjax Function Only Working Part of the Time
    text
    copied!<p>I am using the following Ajax function format:</p> <pre><code>var xmlhttp; function addAddress(str) { if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState == 4 &amp;&amp; xmlhttp.status == 200) { //specific selection text document.getElementById('info').innerHTML = xmlhttp.responseText; } } var addAddress = "add"; xmlhttp.open("POST", "sys.php", true); xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); var queryString = "&amp;addAddress=" + addAddress; xmlhttp.send(queryString); } function GetXmlHttpObject() { if (window.XMLHttpRequest) { return new XMLHttpRequest(); } if (windows.ActiveXObject) { return new ActiveXObject("Micorsoft.XMLHTTP"); } return null; } </code></pre> <p>Up until now, all of my Ajax functions, like the one above, have been running fine. However, now the function will work only sometimes. Now, sometimes I will have to click the onclick event a couple times to execute the function or the function will just hang, and then after about 4 minutes it will execute.</p> <p>I tested parts of the function and found that the issue lies some where at the:</p> <pre><code>if (xmlhttp.readyState == 4 &amp;&amp; xmlhttp.status == 200) { alert(xmlhttp.status); //specific selection text document.getElementById('info').innerHTML = xmlhttp.responseText; } </code></pre> <p>When the function works, I can alert(xmlhttp.status) and get 200. However, when it's not working, the alert box doesn't even trigger. In fact, nothing happens, not even an error.</p> <p>Could this be a server issue? I am kind of thinking my website got hacked, but I cannot find any issues accept that the Ajax functions are not executing properly.</p> <p>Lastly, I do not get this problem on my localhost, it's only happening on the live website.</p> <p>Any help will be greatly appreciated.</p> <p>Thanks</p>
