【问题描述】：
我正在为我的 Web 应用程序使用 Spring MVC、Hibernate、MySQL、JSP 和 JQGrid。在尝试实现一个页面时，我遇到了如下所述的奇怪行为：
- 传递给JSP的JSON数据正确，在所有列中都有效
- 但是，在 28 列中，21 列中的数据正确显示，但 7 列中的数据根本不显示。这 7 列是前 4 列，其他 3 列在中间。
-
js-for-acctmst.js文件相关部分如下：
grid.jqGrid({ datatype: 'json', mtype: 'GET', height: 'auto', url:'/NioERPJ/admin/acctmstmgmt/', editurl:'/NioERPJ/admin/acctmstmgmt/edit', colNames:['Company Code','A/c Code','A/c Description','BA Code', 'Sched', 'Rel.

我无法解决为什么 JQGrid 中不显示某些列的问题？ pl。帮助。
我正在从 apache 日志中添加以下调试输出
调试 o.h.internal.util.EntityPrinter - com.nej.acctmst.model.AcctMst{rel_code=2, tran_dr=2.0, perc=2.0, bpta=2, dateop_cr=2.0, acc_des=Test - 2, out_field=true, sflag=true, sgn=2, net=2.0, fnd=true, op_cr=2.0, add3=2.0, ledger=true, dflag=2, Gross=2.0, tran_cr=2.0, ledgersum=true, salecd=2, dateop_dr=2.0, sched=2, header=false, op_dr=2.0, t_o_ac=2, ba_code=2, 用户名=Test-2} 18:39:23.163 [http-apr-8080-exec-25] 调试 o.h.internal.util.EntityPrinter - com.nej.acctmst.model.AcctMst{rel_code=1, tran_dr=1.0, perc=1.0, bpta=1, dateop_cr=1.0, acc_des=测试账户, out_field=true, sflag=false，sgn=1，net=1.0，fnd=true，op_cr=1.0，add3=1.0， 分类帐=真，dflag=1，总=1.0，tran_cr=1.0，分类帐=真， salecd=1, dateop_dr=1.0, sched=1, header=true, op_dr=1.0, t_o_ac=1, ba_code=1，用户名=测试}
我已经安装了 Fiddler，发现以下 JSON 输出
{"rows":[
{"sched":"1","header":true,"bpta":"1","perc":1.0,"sgn":"1","fnd":true,"ledger":true,
"ledgersum":true,"dflag":"1","gross":1.0,"net":1.0,"sflag":false,"salecd":"1",
"add3":1.0,"username":"Test","opdr":1.0,"opcr":1.0,"toac":"1","dateopdr":1.0,
"acccode":"1","cocode":1,"accdes":"Test Account","bacode":"1","dateopcr":1.0,
"trancr":1.0,"outfield":true,"trandr":1.0,"relcode":"1"},
{"sched":"2","header":false,"bpta":"2","perc":2.0,"sgn":"2","fnd":true,"ledger":true,
"ledgersum":true,"dflag":"2","gross":2.0,"net":2.0,"sflag":true,"salecd":"2",
"add3":2.0,"username":"Test-2","opdr":2.0,"opcr":2.0,"toac":"2","dateopdr":2.0,
"acccode":"2","cocode":2,"accdes":"Test - 2","bacode":"2","dateopcr":2.0,
"trancr":2.0,"outfield":true,"trandr":2.0,"relcode":"2"}
],
"total":1,
"records":2,
"page":1
}
从输出中可以看出，字段的顺序已更改，并且字段名称与 colModel 中的名称不同（在某些字段中，下划线已被删除）。我的诊断正确吗？
【问题讨论】：
-
您应该包含从
url:'/NioERPJ/admin/acctmstmgmt/'返回的测试数据（1-2 行就足够了）。顺便说一句，如果从服务器返回的数据不包含任何 HTML 片段，那么我建议您另外使用autoencode: true选项。如果您要使用更多template和cmTemplete，则可以显着减小colModel的大小并提高其可读性。所有index属性都可以从colModel中删除。jsonReader也可以删除或缩减为jsonReader: {repeatitems: false} -
@Oleg 我添加了日志文件输出。我需要提供 url : '/NioERPJ/admin/acctmstmgmt/open/' 来打开页面。我无法发布输出图像，因为我的分数低于 10。
-
你可以使用你发布的调试输出作为输入而不是
url : '/NioERPJ/admin/acctmstmgmt/open/'吗？我不是。例如，您可以使用 Chrome/IE/Firefox 开发者工具的免费Fiddler 工具来查看 HTTP 流量。您将看到来自'/NioERPJ/admin/acctmstmgmt/open/的确切 JSON 响应。可以将数据保存在文本文件中，并使用文件路径而不是'/NioERPJ/admin/acctmstmgmt/open/。以一种可以重现问题的方式。您只能包含来自真实响应的 2 行数据。 -
@Oleg 感谢您提出改进建议。我会尽快实施。
-
我的意思是您描述了使用特定数据遇到的问题。仅阅读您发布的 JavaScript 很难找到问题的原因。此外，一些问题仅在与输入数据结合时存在。更有效的是拥有重现问题并且可以调试的演示。您可以考虑创建 JSFiddle 演示。查看the example，它展示了如何使用 Echo 服务在 JSFiddle 中使用
datatype: "json"创建演示。
