Many of the existing javascripts snippets you see on the internet to determine whether the DOM is fully loaded do not work properly in Internet Explorer when using the HTTPS secure protocol.  The "normal" script is as follows and works great for HTTP but will throw unsecure item warnings in IE because it adds a script element to the page.  Here is the updated script which works with both secure and unsecure connections:function checkReady() { if (document.addEventListener) { document.addEventListener("DOMContentLoaded", setDOMReady, false); } //Firefox if (document.all && !window.opera) { //IE var proto = "src='javascript:void(0)'"; if (location.protocol == "https:") proto = "src=//:"; document.write("<scr" + "ipt id=__ie_onload defer " + proto + "><\/scr" + "ipt>"); var contentloadtag = $("__ie_onload"); contentloadtag.onreadystatechange = function() { if (this.readyState == "complete") { setDOMReady(); } }; } if(/Safari/i.test(navigator.userAgent)) //Safari { var _timer=setInterval(function() { if(/loaded|complete/.test(document.readyState)) { clearInterval(_timer); setDOMReady(); // call target function } }, 10); } };
