我需要自定义jqGrid。但postData.Filters未定义。由于我是jquery和javascript的新手，即使经过一天的努力，我也无法找出究竟是什么问题。
我正在使用以下javascript。

我看到你使用my old answer中的代码。
错误＆＃34; jqGrid postData.filters未定义＆＃34;通过添加行
可以很容易地修复undefinedif (postData.filters == null) {
return;
}
modifySearchingFilter之前的var filters = $.parseJSON(postData.filters);内部。
代码中的其他重要错误是datatype: "json"而非datatype: "local"的使用。选项datatype: "json"表示网格中的数据将通过Ajax请求加载到url参数指定的URL。
另一个错误是使用data: jsonData而不是data: jsonData.Employees。了解data参数的值必须是数组非常重要。
还有一句话：我严格建议您不要在name的{{1}}属性中使用任何特殊字符（目前您有colModel）。 name: "Emp ID"属性的值将用作网格的某些内部元素的name，但空间将由jQuery和CSS用作分隔符和元字符（请参阅here例如）。因此，我建议您将id更改为name: "Emp ID"，以便将来减少问题。
您将被罚款here的固定演示。它使用以下代码
name: "EmpId"
