var iframe = document.createElement("iframe");iframe.src = "http://www.planabc.net";if (iframe.attachEvent){    iframe.attachEvent("onload", function(){        alert("Local iframe is now loaded.");    });} else {    iframe.onload = function(){        alert("Local iframe is now loaded.");    };}document.body.appendChild(iframe);
