我想使用filtertoolbar，但使用接受不同过滤器参数的服务器。jqGrid postData.filter返回undefined
我试图找到过滤器参数为了操纵postData。
上beforeSearch，我试图提取使用过滤器：
var postData = $("#jqGrid").jqGrid('getGridParam','postData');
alert(postData.filters);
未定义所有的时间postData.filter回报。
再次要注意的是，服务器没有它的json请求方案中的任何“过滤器”概念，所以json请求由我填充。
这里的功能：{
var pageOffset = (sessionPage - 1) * pageLength;
var totalList = 0;
var pageNumber = 0;
var totalPages = 0;

postData: sessionListData(pageOffset),
datatype: "json",
onPaging: function(pgButton) {
var requestedPage = $(".ui-pg-input").val();
if (pgButton == "user") {
// find out the requested and last page
var lastPage = $("#jqGrid").getGridParam("lastpage");
// if the requested page is higher than the last page value
if (requestedPage > lastPage) {
// set the requested page to the last page value - then reload
$("#jqGrid").setGridParam({page:lastPage});
sessionPage = lastPage;
} else {
sessionPage = $(".ui-pg-input").val();
}
} else if (pgButton == "next_jqGridPager") {
sessionPage = +$(".ui-pg-input").val() + +1;
} else if (pgButton == "prev_jqGridPager") {
sessionPage = $(".ui-pg-input").val() - 1;

感谢，对MTYPE： “POST”， \t \t \t \t数据类型： “JSON”，并stringResult设置为true。 。 – Tal 2015-02-23 12:18:44
