在datagrid的所有columns 可以通过点击列表头排序,你可以定义哪行可以排序,默认的列是不能排序的除非你设置sortable 属性为true
创建an DataGrid
<table id="tt" class="easyui-datagrid" style="width:600px;height:250px" url="datagrid8_getdata.php" title="Load Data" iconCls="icon-save" rownumbers="true" pagination="true"> <thead> <tr> <th field="itemid" width="80" sortable="true">Item ID</th> <th field="productid" width="80" sortable="true">Product ID</th> <th field="listprice" width="80" align="right" sortable="true">List Price</th> <th field="unitcost" width="80" align="right" sortable="true">Unit Cost</th> <th field="attr1" width="150">Attribute</th> <th field="status" width="60" align="center">Stauts</th> </tr> </thead> </table>我们定义一些可排序的列包含itemid,productid,listprice,unitcost等等"attr1" 列和 "status"列不能排序.
$page = isset($_POST["page"]) ? intval($_POST["page"]) : 1; $rows = isset($_POST["rows"]) ? intval($_POST["rows"]) : 10; $sort = isset($_POST["sort"]) ? strval($_POST["sort"]) : "itemid"; $order = isset($_POST["order"]) ? strval($_POST["order"]) : "asc"; $offset = ($page-1)*$rows; $result = array(); include "conn.php"; $rs = mysql_query("select count(*) from item"); $row = mysql_fetch_row($rs); $result["total"] = $row[0]; $rs = mysql_query("select * from item order by $sort $order limit $offset,$rows"); $items = array(); while($row = mysql_fetch_object($rs)){ array_push($items, $row); } $result["rows"] = $items; echo json_encode($result);
