伙计们，我有以下脚本用于在 mysql 中添加、编辑和删除内容，并在 index.php 文件中显示它。所以这是我的 index.php 文件：
<script>function goDel()
{
var recslen = document.forms[0].length;
var checkboxes=""
for(i=1;i<recslen;i++)
{
if(document.forms[0].elements[i].checked==true)
checkboxes+= " " + document.forms[0].elements[i].name
}
if(checkboxes.length>0)
{
var con=confirm("Are you sure you want to delete");
if(con)
{
document.forms[0].action="delete.php?recsno="+checkboxes
document.forms[0].submit()
}
}
else
{
alert("No record is selected.")
}
}
function selectall()
{
// var formname=document.getElementById(formname);
var recslen = document.forms[0].length;
if(document.forms[0].topcheckbox.checked==true)
{
for(i=1;i<recslen;i++) {
document.forms[0].elements[i].checked=true;
}
}
else
{
for(i=1;i<recslen;i++)
document.forms[0].elements[i].checked=false;
}
}
</script>
<style type="text/css">
<!--
.style1 {color: #FFFFFF}
-->
</style>
</head>
<body>
<table width="775" border="0" align="center" cellpadding="0" cellspacing="0" bgcolor="#FFFFFF">
<tr>
<td><hr size="1" noshade></td>
</tr>
<tr>
<td>
<form action="" method="post" name="" id="">
<table width="600" border="1" align="center" cellpadding="2" cellspacing="2">
<tr>
<td><input name="topcheckbox" type="checkbox" class="check" id="topcheckbox" onClick="selectall();" value="ON">
Select All </td>
<td colspan="3" align="center"><a href="form.php?mode=add">Add New Branch </a></td>
</tr>
<tr>
<td><strong><a href="javascript:goDel()">Delete</a></strong></td>
<td><strong>Branch Name </strong></td>
<td><strong>Short Name </strong></td>
<td><strong>Update</strong></td>
</tr>
<?
include("conn.php");
$sql="select sn,branchname,shortname from $branch order by sn";
$result=mysql_query($sql,$connection) or die(mysql_error());
while($row=mysql_fetch_array($result)) {
?>
<tr>
<td><input name="<? echo $row['sn']; ?>" type="checkbox" class="check"></td>
<td><? echo $row['branchname']; ?></td>
<td><? echo $row['shortname']; ?></td>
<td><a href="<? echo "form.php?sn=".$row['sn']."&mode=update"; ?>">Update</a></td>
</tr>
<? } ?>
</table>
</form></td>
</tr>
</table>
这是我的 delete.php 文件：
<?php
include("conn.php");
$recsno=$_GET["recsno"];
$data=trim($recsno);
$ex=explode(" ",$data);
$size=sizeof($ex);
for($i=0;$i<$size;$i++) {
$id=trim($ex[$i]);
$sql="delete from $branch where sn='$id'";
$result=mysql_query($sql,$connection) or die(mysql_error());
}
header("location: index.php");
?>
问题是当我检查 1 行并单击删除时，它正在删除所有行，就像我单击全选（我没有这样做）一样。先感谢您。
