Context Menu on Mouse Right Click for IE, FireFox Mozilla, Safari.

After long time, I like to write an article on JavaScript compatibility on different browsers. In this article I am creating a context menu on mouse right click. As we know we can easily create the context menu using javascript, but the main problem is the browser compatibility with this context menu. I am here giving some code to create a context menu. You can use this in any browser. I tested it in Internet Explorer 6.0, Firefox Mozilla 2.0 and Safari 3.0. It's working fine.

Copy and paste the following code in notepad and save it as TestContextMenu.html and test it.

return false

if (firingobj.getAttribute('target'))'url'),firingobj.getAttribute('target'));

if (ie5||ns6)
document.oncontextmenu=showmenuie5 ;


Note: I came to know from some comments that the Code is not working. I here note that the code was not working due to the problem with " character. I don't know but it was encrypted. I retype the code here and think that it will work. Let me know if you found any problem. Thank you...
Enjoy this......
