php - jquery ajax调用删除mysql中的一行

Question

如何通过使用 jquery ajax 调用传递 id 来删除行 这是delete.php

<?php

require_once('DB.class.php');
$dbconnect = new DB('schoollife', 'root', '');

$id=$_GET['chapter_id'];

$del="DELETE FROM sl_chapter WHERE chapter_id=".$id ;
$result=mysql_query($del);

// if successfully deleted
if($result){
echo "<font color='red'>record deleted successful</font>";
//echo "<BR>";
//echo "<a href='delete.php'>Back to main page</a>";
}
else {
echo "<br/>";
die('Error: ' . mysql_error());
} 

?>

这是chapter.html

<script>
 $(document).on('click','.delbutton',function(){ 
        var del_id = element.attr("id");
        var info = 'id=' + del_id;
        if(confirm("Are you sure you want to delete!"))
        {
        $.ajax({
        type: "json",
        url: "delete.php",
        //data: info,
        success: function(){
        }
        });
        $(this).parents(".record").animate({ backgroundColor: "#fbc7c7" }, "fast")
        .animate({ opacity: "hide" }, "slow");
        }
        return false;

        });
            </script>

如何通过使用 jquery ajax 调用传递 id 来删除行 我认为删除查询犯了错误..

差不多了，你需要将要删除的id传递给delete.php

章节.html:

<script>
 $(document).on('click','.delbutton',function(){ 
        var del_id = element.attr("id");
        if(confirm("Are you sure you want to delete!"))
        {
        $.ajax({
        type: "POST", //changed
        url: "delete.php",
        data: 'id=' + del_id, // changed
        success: function(){
        }
        });
        $(this).parents(".record").animate({ backgroundColor: "#fbc7c7" }, "fast")
        .animate({ opacity: "hide" }, "slow");
        }
        return false;

        });
            </script>

删除.php:

require_once('DB.class.php');
$dbconnect = new DB('schoollife', 'root', '');

$id=$_POST['id']; //changed

$del="DELETE FROM sl_chapter WHERE chapter_id=".$id ;
$result=mysql_query($del);

// if successfully deleted
if($result){
echo "<font color='red'>record deleted successful</font>";
//echo "<BR>";
//echo "<a href='delete.php'>Back to main page</a>";
}
else {
echo "<br/>";
die('Error: ' . mysql_error());
} 

?>
