网页如附件图，我想选周一时，其后的一行所有框被选中，再点周一时，所有框取消选择；其余行雷同，会的帮帮呀 <? function numToWeek($num) { $key = '周'; switch($num) { case 0: return $key.'日'; break; case 1: return $key.'一'; break; case 2: return $key.'二'; break; case 3: return $key.'三'; break; case 4: return $key.'四'; break; case 5: return $key.'五'; break; case 6: return $key.'六'; break; case 7: return '假日'; break; } } ?> <script language="javascript"> function switchAll() { for (var m = 0; m <= 7; m++) { for (var k = 0; k < 24; k++) { box = eval("document.form1.weektime" + m + k); box.checked = !box.checked; } } } </script>
