<head>
<script type="text/javascript" language="javascript">
function fun(){
document.f1.btn1.onclick=function(){
alert('htllo'+this)
};
function f(){
document.f1.btn2.value+='hello';
};
document.f1.btn2.onmousemove=f;
document.f1.btn2.onmouseout=function(){
document.f1.btn2.value='btn2';
}
}
fun();
</script></head><body>
<form name="f1">
<input name="btn1" type="button" value="btn1" />
<input name="btn2" type="button" value="btn2" />
</form>
</body>
