jEasyUI树形网格动态加载
动态加载树形网格有助于从服务器上加载部分的行数据,避免加载大型数据的长时间等待。本教程将向您展示如何创建带有动态加载特性的树形网格(TreeGrid)。
创建树形网格(TreeGrid)
<table title="Products" class="easyui-treegrid" style="width:700px;height:300px" url="treegrid3_getdata.php" rownumbers="true" idField="id" treeField="name"> <thead> <tr> <th field="name" width="250">Name</th> <th field="quantity" width="100" align="right">Quantity</th> <th field="price" width="150" align="right" formatter="formatDollar">Price</th> <th field="total" width="150" align="right" formatter="formatDollar">Total</th> </tr> </thead> </table>
服务器端代码
treegrid3_getdata.php
$id = isset($_POST['id']) ? intval($_POST['id']) : 0; include 'conn.php'; $result = array(); $rs = mysql_query("select * from products where parentId=$id"); while($row = mysql_fetch_array($rs)){ $row['state'] = has_child($row['id']) ? 'closed' : 'open'; $row['total'] = $row['price']*$row['quantity']; array_push($result, $row); } echo json_encode($result); function has_child($id){ $rs = mysql_query("select count(*) from products where parentId=$id"); $row = mysql_fetch_array($rs); return $row[0] > 0 ? true : false; }
