没有break语句!!!
<script>var totlepage=20;
{for (var i=1; i<=totlepage; i++)
if (i+1<=7)
{
document.write(""+i+"");
}
else
{ document.write("..."+totlepage+"");
  break;
}
}
</script>

{for (var i=1; i<=totlepage; i++)
if (i<=7)
{
document.write(""+i+"");
}
else
{ document.write("..."+totlepage+"");
  break;
}
}
</script>
