在本教程中，我们将为大家展示如何创建一个CRUD DataGrid。在这期间将使用到可编辑的datagrid插件来同这些crud操作一起工作。

Step 1：在HTML标记中定义DataGrid

<table id="dg" title="My Users" style="width:550px;height:250px"

toolbar="#toolbar" idField="id"

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>

Step 2：制作一个可编辑的DataGrid

$('#dg').edatagrid({

url: 'get_users.php',

saveUrl: 'save_user.php',

updateUrl: 'update_user.php',

destroyUrl: 'destroy_user.php'

});

我们应该为可编辑的datagrid提供"url"、"saveUrl"、"updateUrl"和"destroyUrl"属性：

Step 3：编写服务器处理代码

保存一个新用户（save_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

));

更新一个已存在的用户（update_user.php）：

$id = intval($_REQUEST['id']);

$firstname = $_REQUEST['firstname'];

$lastname = $_REQUEST['lastname'];

$phone = $_REQUEST['phone'];

$email = $_REQUEST['email'];

 

include 'conn.php';

 

$sql="update users set firstname='$firstname',lastname='$lastname',phone='$phone',email='$email' where id=$id";

@mysql_query($sql);

echo json_encode(array(

'id' => $id,

'firstname' => $firstname,

'lastname' => $lastname,

'phone' => $phone,

'email' => $email

));

删除一个已存在的用户（destroy_user.php）：

$id = intval($_REQUEST['id']);

 

include 'conn.php';

 

$sql = "delete from users where id=$id";

@mysql_query($sql);

echo json_encode(array('success'=>true));
