当切换datagrid的view 到 'detailview',用户可以展开一行显示一些行的详细在行下面,这个功能允许你提供一些合适的layout 到里面,编辑form将放置到详细行panel中,在这个教程中,我们使用datagrid 组件通过编辑form减小占据空间.
查看 Demo
<table id="dg" title="My Users" style="width:550px;height:250px" url="get_users.php" toolbar="#toolbar" fitcolumns="true" singleselect="true"> <thead> <tr> <th field="firstname" width="50">First Name</th> <th field="lastname" width="50">Last Name</th> <th field="phone" width="50">Phone</th> <th field="email" width="50">Email</th> </tr> </thead> </table> <div id="toolbar"> <a href="#" class="easyui-linkbutton" iconcls="icon-add" plain="true" onclick="newItem()">New</a> <a href="#" class="easyui-linkbutton" iconcls="icon-remove" plain="true" onclick="destroyItem()">Destroy</a> </div>
$('#dg').datagrid({ view: detailview, detailFormatter:function(index,row){ return '<div class="ddv"></div>'; }, onExpandRow: function(index,row){ var ddv = $(this).datagrid('getRowDetail',index).find('div.ddv'); ddv.panel({ border:false, cache:true, href:'show_form.php?index='+index, onLoad:function(){ $('#dg').datagrid('fixDetailRowHeight',index); $('#dg').datagrid('selectRow',index); $('#dg').datagrid('getRowDetail',index).find('form').form('load',row); } }); $('#dg').datagrid('fixDetailRowHeight',index); } });使用detailview 到datagrid,在html头部引入'datagrid-detailview.js'文件
'onExpandRow'事件将被触发,我们将通过ajax加载编辑form,调用'getRowDetail'方法去得到行详细容器,所以我们能查找到行详细panel,创建一个
panel在行详细中,从'show_form.php'加载编辑form 和返回.
show_form.php
<form method="post"> <table class="dv-table" style="width:100%;background:#fafafa;padding:5px;margin-top:5px;"> <tbody><tr> <td>First Name</td> <td><input name="firstname" class="easyui-validatebox" required="true"></td> <td>Last Name</td> <td><input name="lastname" class="easyui-validatebox" required="true"></td> </tr> <tr> <td>Phone</td> <td><input name="phone"></td> <td>Email</td> <td><input name="email" class="easyui-validatebox" validtype="email"></td> </tr> </tbody></table> <div style="padding:5px 0;text-align:right;padding-right:30px"> <a href="#" class="easyui-linkbutton" iconcls="icon-save" plain="true" onclick="saveItem(<?php echo $_REQUEST['index'];?>)">Save</a> <a href="#" class="easyui-linkbutton" iconcls="icon-cancel" plain="true" onclick="cancelItem(<?php echo $_REQUEST['index'];?>)">Cancel</a> </div> </form>
function saveItem(index){ var row = $('#dg').datagrid('getRows')[index]; var url = row.isNewRecord ? 'save_user.php' : 'update_user.php?id='+row.id; $('#dg').datagrid('getRowDetail',index).find('form').form('submit',{ url: url, onSubmit: function(){ return $(this).form('validate'); }, success: function(data){ data = eval('('+data+')'); data.isNewRecord = false; $('#dg').datagrid('collapseRow',index); $('#dg').datagrid('updateRow',{ index: index, row: data }); } }); }决定那一个url提交然后查找form对象和调用' submit'方法提交form数据,当保存数据成功折叠和更新行数据.
function cancelItem(index){ var row = $('#dg').datagrid('getRows')[index]; if (row.isNewRecord){ $('#dg').datagrid('deleteRow',index); } else { $('#dg').datagrid('collapseRow',index); } }当取消编辑动作,如果是新行而且还没有保存,直接删除行,其他折叠行.
