languageGroup长度和名称是动态的

您包含了错误的JSON数据。1） 有未关闭的引号请参见

“stringID:”blahblah，“product:”blahblah“

而不是

“stringID:”blahblah“，”product:”blahblah“

2）JSON数据与服务器端代码不对应。服务器返回

{“total”：1，“page”：1，“records”：xxx，“cell”：[…]）

。网格中总共可以显示多少行（100、1000、10000、100000等）？使用哪个版本的jqGrid以及jqGrid的哪个分支（、商业版或旧版jqGrid中您是否可以包括一个列标题示例，您希望使用它？JSON数据示例允许在每行数据中使用不同的

Key

。是

languageGroup[i]。Key

是数据的一部分，还是在所有项中都有相同的值？使用

columnNames.push（targetLang[i]）

，其中

targetLang

不是从服务器返回的数据的一部分。它看起来很奇怪。它与

languageGroup[i]有一些关系。Key

？您使用

jsonmap:'languageGroup.+i+'Value'

而不是至少

jsonmap:'languageGroup.+i+'。Value'

（在

值之前加上附加的
）。
i
应以0开头
search.DosearchWord(....) return List< T >  (
     List< KeyValuePair< string,string > > languageGroup,
     String ID,
