步骤1:在HTML标记中定义一个DataGrid

<table id="dg" title="My Users" style="width:550px;height:250px"  
        toolbar="#toolbar"  
        rownumbers="true" fitColumns="true" singleSelect="true">  
    <thead>  
        <tr>  
            <th field="firstname" width="50" editor="{type:'validatebox',options:{required:true}}">First Name</th>  
            <th field="lastname" width="50" editor="{type:'validatebox',options:{required:true}}">Last Name</th>  
            <th field="phone" width="50" editor="text">Phone</th>  
            <th field="email" width="50" editor="{type:'validatebox',options:{validType:'email'}}">Email</th>  
        </tr>  
    </thead>  
</table>  
<div id="toolbar">  
    <a href="#" class="easyui-linkbutton" iconCls="icon-add" plain="true" onclick="javascript:$('#dg').edatagrid('addRow')">New</a>  
    <a href="#" class="easyui-linkbutton" iconCls="icon-remove" plain="true" onclick="javascript:$('#dg').edatagrid('destroyRow')">Destroy</a>  
    <a href="#" class="easyui-linkbutton" iconCls="icon-save" plain="true" onclick="javascript:$('#dg').edatagrid('saveRow')">Save</a>  
    <a href="#" class="easyui-linkbutton" iconCls="icon-undo" plain="true" onclick="javascript:$('#dg').edatagrid('cancelRow')">Cancel</a>  
</div>  

步骤2: 使DataGrid可编辑

$('#dg').edatagrid({  
    url: 'get_users.php',  
    saveUrl: 'save_user.php',  
    updateUrl: 'update_user.php',  
    destroyUrl: 'destroy_user.php'  
}); 

$firstname = $_REQUEST['firstname'];  
$lastname = $_REQUEST['lastname'];  
$phone = $_REQUEST['phone'];  
$email = $_REQUEST['email'];  
  
include 'conn.php';  
  
$sql = "insert into users(firstname,lastname,phone,email) values('$firstname','$lastname','$phone','$email')";  
@mysql_query($sql);  
echo json_encode(array(  
    'id' => mysql_insert_id(),  
    'firstname' => $firstname,  
    'lastname' => $lastname,  
    'phone' => $phone,  
    'email' => $email  
));  

1. $id = intval($_REQUEST['id']);  
2.   
3. include 'conn.php';  
4.   
5. $sql = "delete from users where id=$id";  
6. @mysql_query($sql);  
7. echo json_encode(array('success'=>true));
