Edit table menggunakan jquery dan ajax

Bagaimana cara agar kita dapat mengedit informasi user agar dapat mempermudah kan dalam mengupdate tanpa harus mengkilik tombol edit, berikut ini contoh beberapa variasi update data.

Jadi ketika kursor kita arahkan ke salah satu nama yang ingin di update maka hanya tingal mengklik nama tersebut kemudian tinggal di ubah atau di ganti. berikut ini adalah tahapan- tahapan memulai membuat table edit tersebut

Database

CREATE TABLE fullnames
(
id INT PRIMARY KEY AUTO_INCREMENT,
firstname VARCHAR(70),
lastname VARCHAR(70)
);

 

TableEdit.php

<table>
<?php
include('db.php');
$sql=mysql_query("select * from fullnames");
while($row=mysql_fetch_array($sql))
{
$id=$row['id'];
$firstname=$row['firstname'];
$lastname=$row['lastname'];
?>
<tr id="<?php echo $id; ?>" class="edit_tr">

<td class="edit_td">
<span id="first_<?php echo $id; ?>" class="text"><?php echo $firstname; ?></span>
<input type="text" value="<?php echo $firstname; ?>" class="editbox" id="first_input_<?php echo $id; ?>" /&gt;
</td>

<td class="edit_td">
<span id="last_<?php echo $id; ?>" class="text"><?php echo $lastname; ?></span>
<input type="text" value="<?php echo $lastname; ?>" class="editbox" id="last_input_<?php echo $id; ?>"/>
</td>

</tr>
<?php
}
?>
</table>

table_edit_ajax.php

<?php
include("db.php");
if($_POST['id'])
{
$id=mysql_escape_String($_POST['id']);
$firstname=mysql_escape_String($_POST['firstname']);
$lastname=mysql_escape_String($_POST['lastname']);
$sql = "update fullnames set firstname='$firstname',lastname='$lastname' where id='$id'";
mysql_query($sql);
}
?>

JavaScript code

<script type="text/javascript" src="http://ajax.googleapis.com/
ajax/libs/jquery/1.5/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$(".edit_tr").click(function()
{
var ID=$(this).attr('id');
$("#first_"+ID).hide();
$("#last_"+ID).hide();
$("#first_input_"+ID).show();
$("#last_input_"+ID).show();
}).change(function()
{
var ID=$(this).attr('id');
var first=$("#first_input_"+ID).val();
var last=$("#last_input_"+ID).val();
var dataString = 'id='+ ID +'&firstname='+first+'&lastname='+last;
$("#first_"+ID).html('<img src="load.gif" />'); // Loading image

if(first.length>0&& last.length>0)
{

$.ajax({
type: "POST",
url: "table_edit_ajax.php",
data: dataString,
cache: false,
success: function(html)
{
$("#first_"+ID).html(first);
$("#last_"+ID).html(last);
}
});
}
else
{
alert('Enter something.');
}

});

// Edit input box click action
$(".editbox").mouseup(function()
{
return false
});

// Outside click action
$(document).mouseup(function()
{
$(".editbox").hide();
$(".text").show();
});

});
</script>

$mysql_hostname = "Host name";
$mysql_user = "UserName";
$mysql_password = "Password";
$mysql_database = "Database Name";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");
?>
