js错误，参数不能正确显示

请教下面程序的有什么问题？input单标记
<script type="text/javascript">

window.onload=apple;
function apple()
{
var pup_time_h = document.getElementById('pup_time_h');
var pup_time_m = document.getElementById('pup_time_m');
var up_h = document.getElementById('up_h');
var up_m = document.getElementById('up_m');

var num_1,num_2,temp,hour_num,minu_num;

var result,submit;

temp=0;
num_1 = pup_time_h*60 + pup_time_m;
num_2 = up_h*60 + up_m;
temp=num_1-num_2;
hour_num=0;
minu_num=0;

for (var i=0; i<30; i++) {
if (temp >= 60 ) {
temp=temp-60;
hour_num=hour_num+1;
}
if (temp<60 && temp>0)
minu_num=temp;
}

submit.onclick=function()
{
document.getElementById("hour_num").value=hour_num;
document.getElementById("minu_num").value=minu_num;
}
}
</script>

Answer 1

onclick事件应该添加在元素上。
看你给出的代码，submit是定义的一个变量。
