靠，排版。



<script language="javascript">

function selectAll()

{ 

 var CheckBoxList = document.getElementsByTagName('input');

    for(var i=0;i<CheckBoxList.length;i++)

    {

      if(CheckBoxList[i].type == 'checkbox') 

         CheckBoxList[i].checked=true;

    }

 }

</script>

<body> 

<form action="getchk.php" method="post"> 

<table> 

<tr> <td> <input type="checkbox" name="chk[]" value="a">1 </td> </tr> 

<tr> <td> <input type="checkbox" name="chk[]" value="b">2 </td> </tr> 

<tr> <td> <input type="checkbox" name="chk[]" value="c">3 </td> </tr> 

<tr> <td> <input  type="button" value="全选" onclick ="selectAll()"> </td> </tr>

有点儿小错误，应该是这样的：

[code=JScript]<script language="javascript">

function selectAll()

{ 

 var CheckBoxList = document.getElementsByTagName('input');

    for(var i=0;i<CheckBoxList.length;i++)

    {

      if(CheckBoxList[i].type == 'checkbox') 

         CheckBoxList[i].checked=true;

    }

 }

</script>

<html>
<body>
<form action="getchk.php" method="post">
<table>
<tr> <td> <input type="checkbox" name="chk[]" value="a">1 </td> </tr>
<tr> <td> <input type="checkbox" name="chk[]" value="b">2 </td> </tr>
<tr> <td> <input type="checkbox" name="chk[]" value="c">3 </td> </tr>
<tr> <td> <input type="button" value="全选" onclick ="selectAll()"> </td> </tr>
</table>
<input type="submit" value="Submit">
</form>
</body>
</html>
[/code]

PHP就用你的不用改



$p_chk=$_POST["chk"];

echo "Count Checkbox : ".count($p_chk)." <br>";

echo "Their values are : <br>";

for($i=0;$i <count($p_chk);$i++)

{

  echo $p_chk[$i]." <br>";

}
