该插件组小巧使用方便,以下是一个从前台提交查询条件,从MSSQL返回json数据的一个事例
HTML前端代码
<?php include_once("auth.php"); ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <link rel="stylesheet" type="text/css" href="/inc/js/EasyUI/themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="/inc/js/EasyUI/themes/icon.css"> <script type="text/javascript" src="/inc/js/EasyUI/jquery-1.8.0.min.js"></script> <script type="text/javascript" src="/inc/js/EasyUI/jquery.easyui.min.js"></script> <script> function FindData(){ $('#mytable').datagrid('load',{ PersonCode:$('#PersonCode').val(), KQYM:$('#KQYM').val()} ); } </script> </head> <body> <table id='mytable' class="easyui-datagrid" style="width:600px;height=500px" url="loadgriddata_get.php" title="请输入查询条件" rownumbers="true" toolbar="#searchtool" loadMsg="正在查询..."> <thead> <tr> <th field="PersonCode" Width="80">工号</th> <th field="MyName" width="80">姓名</th> <th field="KQDate" width="100">考勤日期</th> <th field="MyWeek" width="80">星期</th> <th field="KQMemo" width="200">打卡时间</th> </tr> </thead> </table> <div id="searchtool" style="padding:5px"> <span>工号:</span><input type="text" id="PersonCode" value="" size=10 /> <span>考勤年月:</span><input type="text" id="KQYM" value="" size=10 /> <a href="javascript:FindData()" class="easyui-linkbutton" data-options="iconCls:'icon-search'">查询</a> <div> </body> </html>
以下是取数据集,并将数据组装成json对象返回给前台的php代码
<?php include_once("auth.php"); include_once("inc/ms_conn.php"); include_once("inc/comm_function.php"); $PersonCode=$_POST["PersonCode"]; //前端传来的参数 $KQYM=$_POST["KQYM"]; $sqlstr="Exec dbo.HR_Prg_GetPersonYMKQ2 '$KQYM','$PersonCode'"; $rs =mssqlquery($sqlstr); //自定义的mssql方法,类拟mssql_query方法 $row = mssql_num_rows($rs); //取行总行数 $result["total"] = $row; $items =array(); while ($row = mssql_fetch_array($rs)){ foreach($row as $key=>$value){ //这里很重要,php的json_encode只支持utf-8,否则含汉字字段值会被置为null $row[$key]=iconv('gb2312','UTF-8',$row[$key]); } array_push($items, $row); } $result["rows"] =$items; echo json_encode($result); ?>
以下为效果图
