IE 8/ 9 doesn't support onload()/ onerror event

IE 8/ 9 doesn't support onload()/ onerror event. It is supported on IE 10.

Always perform browser check in the code. For example using onload function, always perform check like -

var scriptlocale = document.createElement("script");

// block executed for IE8/ IE9

if(typeof (scriptlocale.onload) === "undefined"){

}

// executed in case of IE10 browser

else{

scriptlocale.src = "testScript.js"';

scriptlocale.onload = executeOnLoadCallBack;

scriptlocale.onerror = executeOnErrorCallBack;

}
