I was suggesting my code to replace only your .setAttribute() method, not particularly for anything else. I did not check your code for the User object you created, for example.
You need to keep in mind that the DOM object (like a paragraph or div or span or any other DOM object) will have the .addEventListener() method in the browser you may be using for debugging.
But if you intend this code to be executed in IE, Chrome, Safari and other browsers, once you finish with yours, you may need to add cross-browser functionality to it especially for people running older versions of IE. The use of .addEventListener() will generate an error for them, which is why you need to know IE's version of it, method .attachEvent(), and why you also need to test your code in all the browsers where it will run. Yes, it is possible. Some people install Win95/98 and WinXP, and a distro of Linux in 3 or 4 virtual machines, then open the browser and your web page to see what gives. Be thorough as a web developer.
Hi seniseven, you are right! I have to add the source code for IE. So this code:
if (parag.addEventListener) // for Mozilla and friends
else if (parag.attachEvent) // for IE
will be enough, won't it???
Also I have to test the "bind" function on IE. I am affraid it will not work.....
