jQuery EasyUI 教程
本實例演示如何從服務(wù)器端加載數(shù)據(jù),如何添加分頁組件(pagination)到數(shù)據(jù)網(wǎng)格(datagrid)。
為了從遠程服務(wù)器端加載數(shù)據(jù),您應(yīng)該設(shè)置 'url' 屬性,在您的服務(wù)器端應(yīng)該返回 JSON 格式數(shù)據(jù)。請看數(shù)據(jù)網(wǎng)格(datagrid)文檔得到更多關(guān)于它的數(shù)據(jù)格式信息。
????<table id="tt" class="easyui-datagrid" style="width:600px;height:250px" ????????????url="datagrid2_getdata.php" ????????????title="Load Data" iconCls="icon-save" ????????????rownumbers="true" pagination="true"> ????????<thead> ????????????<tr> ????????????????<th field="itemid" width="80">Item ID</th> ????????????????<th field="productid" width="80">Product ID</th> ????????????????<th field="listprice" width="80" align="right">List Price</th> ????????????????<th field="unitcost" width="80" align="right">Unit Cost</th> ????????????????<th field="attr1" width="150">Attribute</th> ????????????????<th field="status" width="60" align="center">Stauts</th> ????????????</tr> ????????</thead> ????</table>
我們定義數(shù)據(jù)網(wǎng)格(datagrid)列,并設(shè)置 'pagination' 屬性為 true,它將在數(shù)據(jù)網(wǎng)格(datagrid)的底部生成一個分頁(pagination)工具欄。pagination將發(fā)送兩個參數(shù)到服務(wù)器:
????$page = isset($_POST['page']) ? intval($_POST['page']) : 1; ????$rows = isset($_POST['rows']) ? intval($_POST['rows']) : 10; ????// ... ????$rs = mysql_query("select count(*) from item"); ????$row = mysql_fetch_row($rs); ????$result["total"] = $row[0]; ???? ????$rs = mysql_query("select * from item limit $offset,$rows"); ???? ????$items = array(); ????while($row = mysql_fetch_object($rs)){ ????????array_push($items, $row); ????} ????$result["rows"] = $items; ???? ????echo json_encode($result);
