jQuery EasyUI 教程
在上一章節(jié)中,我們使用對(duì)話框(dialog)組件創(chuàng)建了 CRUD 應(yīng)用來(lái)創(chuàng)建和編輯用戶信息。本教程我們將告訴您如何創(chuàng)建一個(gè) CRUD 數(shù)據(jù)網(wǎng)格(DataGrid)。 我們將使用 可編輯的數(shù)據(jù)網(wǎng)格(DataGrid)插件 來(lái)完成這些 CRUD 操作動(dòng)作。
<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>
$('#dg').edatagrid({ ????url: 'get_users.php', ????saveUrl: 'save_user.php', ????updateUrl: 'update_user.php', ????destroyUrl: 'destroy_user.php' });
我們應(yīng)該提供 'url'、'saveUrl'、'updateUrl' 和 'destroyUrl' 屬性來(lái)編輯數(shù)據(jù)網(wǎng)格(DataGrid):
保存一個(gè)新的用戶(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 ));
更新一個(gè)已存在用戶(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 ));
刪除一個(gè)已存在用戶(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));
