几秒后才能点按扭的源代码
重点在于setTimeout方法的应用，IE6及FF2下测试通过

<input id="button" name="" type="button" value="10注册" disabled />
<script type="text/javascript">...
window.onload=function()...{
    bindButton(10);
}
function bindButton(num)...{
    window.setTimeout("viewButton("+num+")",1000);
}
function viewButton(i)...{
    var obj=document.getElementById("button");
    i=i-1;
    obj.value=i+"注册";
    if(i>0)...{
        bindButton(i);
    }else...{
        obj.value="注册";
        obj.disabled=false;
    }
}
</script>
