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。

jQuery EasyUI构建CRUD DataGrid教程

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:

  • url:从服务器获取用户数据。
  • saveUrl:保存一个新用户的数据。
  • updateUrl:更新一个已存在的用户的数据。
  • destroyUrl:删除一个已存在的用户的数据。

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));
