};?

setFont();
</script>

<body onload="Javascript:abc(2)">
hello
</body>
</html>

The onclick functions do not work in IE but work fine in chrome and firefox. I could not find the mistake. Why a normal function does not work. function loads the contents but onclicking the first two buttons for which event handelers are writen does not change the button colour in IE only. Please help me... Thanks in advance

The problem here is that using document.write apparently overwrites JavaScript as well. If you switch your document.write() to document.body.innerHTML += your problem is solved. Your latter two buttons won't work with that code because you are calling button 0 and 1 exclusively, while those second two are 3 and 4.
