Question

任何Body都可以告诉我如何在JqGrid中配置主键。由于Jqgrid使用id作为主键但我使用fid作为主键。

Jqgrid示例：

Answer 1

您可以使用

jsonReader: {repeatitems: false, id: "fid" }

或使用

jsonReader: {repeatitems: false }

并为'fid'列定义定义其他key:true属性：

{ name:'fid', index:'fid', key:true, width:55 }

key:true属性覆盖id的{{1}}属性。

还有一句话：如果您想使用表单编辑的jsonReader和closeAfterEdit: true设置，您应该在另一个地方定义：作为closeAfterAdd: true参数的一部分：

navGrid

Id以外的JqGrid主键
