I created an iframe dynamically and found that this iframe trigger onload event twice.
var i=0;
frameOnload=function(){
console.log(i++);
};
var ifr=document.createElement(iframe);
ifr.src=javascript:(function(){document.open();document.write('test');document.close();})();;
ifr.onload=frameOnload;
document.body.appendChild(ifr);
Why i finally is 1?
How to prevent iframe's onload twice instead of pointing onload function to null inside itself?
