  1. 下面的代码是我的 JQGRID 代码，我使用 JsonReader 在网格中绑定数据。还可以找到下面发布的图片。

2.我的服务响应是 JSON，所以我使用 JSON Reader，如果我更改为“localReader”，数据不绑定。

这是我的 JQgrid 寻呼机，即使没有数据，寻呼机也会显示 1 of 0。

jQuery(document).ready(function () {
        $("#datagrid").jqGrid({
            url: service url,
            ajaxGridOptions: { contentType: 'application/json; charset=utf-8' },
            type: "GET",
            datatype: "json",
            colNames:['Id','MID','Status','VendorID','VendorName','InvoiceNo','DocDate','Amount','DocNo','Type','DueDate','ClDoc','Text','UserName','Currency','ConCode','Region','Stat','Process','Comb','Comments'],
            colModel:[
    {name:'id',index:'id', width:50,sortable:true},

您已经引用了正确的答案，这可能会对问题起到额外的作用。我想你已经使用了最新版本的 jqGrid 和描述的修复。

我认为你的问题的根源很简单。您使用的选项jsonReader包含page定义为的属性

page: function () { return 1; }

这意味着即使来自服务器的响应包含空数组，它也会显示第 1 页。我认为您应该将代码更改为以下内容

page: function (obj) { return obj.length > 0 ? 1 : 0; }

或者

page: function (obj) { return obj.length > 0 ? "1" : "0"; }
