PHP 执行部分：
<?php
include('checkadmin.php');
header('Content-Type: text/html; charset=utf-8');
if($_POST['btnSave']){ if(empty($_POST['id'])){
echo"<script>alert('必须选择一个产品,才可以删除!');history.back(-1);</script>";
exit;
}else{
/*如果要获取全部数值则使用下面代码*/ $id= implode(",",$_POST['id']);
$str="DELETE FROM `product` where id in ($id)";
mysql_query($str);
echo "<script>alert('删除成功！');window.location.href='product_list.php';</script>";
}
}
?>
HTML 页面部分：
<form id="form2" name="form2" method="post" action="del_product.php">
<label>
<input type="checkbox" name="id[]" value="1" style="background:none; border:none;" />

JS判断部分：
<script type="text/javascript" language="javascript">
function selectBox(selectType){
var checkboxis = document.getElementsByName("id[]");
if(selectType == "reverse"){
for (var i=0; i<checkboxis.length; i++){
//alert(checkboxis[i].checked);
checkboxis[i].checked = !checkboxis[i].checked;
}
}
else if(selectType == "all")
{
for (var i=0; i<checkboxis.length; i++){
//alert(checkboxis[i].checked);
checkboxis[i].checked = true;
}
}
}
</script>
