for (j=0;j<procuct.length;j++)

procuct.length的procuct拼写错误，你定义的是product

粗略看一下，是switch语法有误，要改为一下的



switch(number)
{
case 0:
temp=myForm.sp0.checked;break;
case 1:
temp=myForm.sp1.checked;break;
case 2:
temp=myForm.sp2.checked;break;
case 3:
temp=myForm.sp3.checked;break;
case 4:
temp=myForm.sp4.checked;break;
case 5:
temp=myForm.sp5.checked;break;
}
