我对jQuery和Javascript一般都很陌生，所以我在尝试理解它是如何工作方面遇到了很多麻烦。我正在使用jQgrid来显示SQL Server中运行的数据库中的某些行，我已经能够显示表中的信息并能够按降序或升序排序，甚至可以显示更多记录。 唯一不起作用的是分页和搜索工具，我真的不明白为什么一旦它加载数据就不能理解它，它在本地操作它并且它不需要做对服务器的任何更多请求。会是什么呢？此外，我已经完成了我的研究，并且我已经看到有一个名为'editurl'的变量，我并不真正了解它的目的。
这是我的javascript代码
jQuery(document).ready(function() {
var myGrid = $("#mygrid").jqGrid({
url:'admanagerjson.php',
datatype: 'json',
mtype: 'GET',
colModel: [
{name:'Sucursal', index:'Sucursal', width:20},

sortname: 'Pedido',

});
myGrid.jqGrid('navGrid','#mypager',{edit:false,add:false,del:false,search:true});
});`
这是我的php：

$limit = $_GET['rows'];// get how many rows we want to have into the grid
$sidx = $_GET['sidx'];// get index row - i.e. user click to sort
$sord = $_GET['sord']; // get the direction if(!$sidx)*/
if(!$sidx) $sidx =1;
// connect to the database
$db = odbc_connect($dsn, $dbuser, $dbpassword) or die("Connection Error: " . odbc_error());
$result = odbc_exec($db, "SELECT COUNT(*) AS count FROM Publi_vwAdmgrPedidos");
$row = odbc_fetch_array($result);
$count = $row['count'];
if( $count > 0 ) {
$total_pages = ceil($count/$limit);
}
else {
$total_pages = 0;
}
if ($page > $total_pages) $page=$total_pages;
$start = $limit*$page - $limit; // do not put $limit*($page - 1)
if($start <0) $start = 0;
$SQL = "SELECT TOP $limit * FROM Publi_vwAdmgrPedidos ORDER BY $sidx $sord";
$result = odbc_exec($db, $SQL) or die("Couldn't execute query.".odbc_error());
$response->page = $page;
$response->total = $total_pages;
$response->records = $count;
$i=0;
while($row = odbc_fetch_array($result)) {
$response->rows[$i]['id']=$row['Pedido'];
$response->rows[$i]['cell']=array($row['Sucursal'],
$row['Pedido'],

答案 0 :(得分：1)
editurl是您提供的用于执行jqGrid内联编辑功能的创建，更新，删除功能的URL。即，当您在网格上编辑记录时，请求将发送到editurl进行处理。
您必须在查询中使用$page varable来获取请求的页面并将其数据作为JSON返回。请记住，对于每个页面，jqGrid都要求服务器返回该页面，但在所有情况下，您只返回第一页。
您的查询可能类似于：
$SQL = "SELECT TOP $limit * FROM
(SELECT ROW_NUMBER() OVER ( ORDER BY $sidx $sord)
as id_column, * FROM Publi_vwAdmgrPedidos)
as table1 where table1.id_column > ($page-1)*$limit ";
免责声明：我没有检查过查询，请确保没有错误。
