这个简单易懂，丢进去就好了，open是打开新页面。alert是弹出一个提示框。
<input type="button" onclick="check()" />
<script>
check(){
open("#.html");
alert("hello world");
}
</script>2010-12-25
onblur 失去焦点响应事件
onfocus 获得焦点响应事件
<script type="text/javascript">
function fun() {
alert("ok");
}
</script>
<input type="text" name="input" onfocus="fun()"/>2010-12-25
