而且，我的jqGrid代码如下所示：
$(document).ready(function () {
$("#jqGrid").jqGrid({
url: 'LibraryWebService.asmx/GetCharts',
mtype: "POST",
dataType: 'json',
contentType: 'application/json; charset=utf-8',
colModel: [
{ label: 'Guid', name: 'Guid', key: true, width: 75 },
{ label: 'group_name', name: 'group_name', width: 100 },
{ label: 'Name', name: 'Name', width: 150 },
{ label: 'ChartOwner', name: 'ChartOwner', width: 75 },
{ label: 'pathname', name: 'pathname', width: 250 }
],
page: 1,
width: 780,
height: 250,
rowNum: 20,
multiselect: true,
scrollPopUp: true,
scrollLeftOffset: "83%",
viewrecords: true,
gridview: true,
loadonce: true,
scroll: 1, // set the scroll property to 1 to enable paging with scrollbar - virtual loading of records
emptyrecords: 'Scroll to bottom to retrieve new page', // the message will be displayed at the bottom
pager: "#jqGridPager"
});
$("#getselected").click(function () {
var sr = $("#jqGrid").jqGrid('getGridParam', 'selarrrow');
if (sr.length) {
alert(sr.join());
} else {
alert("no charts are selected!");
}
});
});
网格未显示。 当我删除scroll = 1属性时，我看到空网格和寻呼机为：第1页，共0页。
答案 0 :(得分：0)
人们可以看到＆＃34;响应Json＆＃34;是XML而没有JSON。您应该更改代码的服务器部分以不返回XML包装器。
另外要了解ASMX方法应该返回object而不是string，这一点非常重要。您不需要将对象手动转换为JSON字符串。转换根据请求的Accept HTTP标头中的信息自动为您执行XML或JSON。
此外，您应该替换不存在的选项 dataType: 'json'和contentType: 'application/json; charset=utf-8' to数据类型：＆＃39; json＆＃39; and ajaxGridOptions：{contentType： ＆＃39;应用/ JSON;字符集= UTF-8＆＃39;}`
我建议您删除scroll: 1选项并使用标准分页。
如果您使用loadonce: true选项，则可以跳过服务器响应中的"records":"830","page":1,"total":42,"rows"部分。您可以将所有 830记录作为项目数组（当前响应中rows属性的值）返回。
