我组合了代码the previous answer关于坚持jqGrid列首选项与从another answer的代码，其中我建议实现持续选择行的代码。值得一提的是，在multiselect:true的情况下，将使用选定行的ID数组，其中包含所有选中的，即使这些行在另一页上也是如此。它非常实用，实现非常简单。所以我发布了相应的feature request，但它一直没有回答。
现在我可以展示两个演示：the first demo其中使用multiselect: true和the second demo它使用相同的代码，但具有单个选择。
我使用的代码中最重要的部分将在下面找到。
有一件事非常重要：您应该在每个使用的页面中修改myColumnStateName的值。变量的值包含localStorage中列状态的名称。所以你不会改变名字，你会分享不同表格的状态，这可能会导致非常奇怪的效果。您可以考虑使用从当前页面的名称或其URL构成的名称作为值myColumnStateName。

修订：我忘了提及，与jqGrid的4.3它是使用这里所描述the fix非常重要的用途multiselect: true选项的情况下。在第一个演示中，我使用了包含错误修复的jquery.jqGrid.src.js的the modified version。
UPDATED 2：为了便于生成用于保存网格状态的本地存储项的唯一名称，我稍微修改了这些演示。的the multiselect demo和the single select demo使用myColumnStateName作为函数的下一个版本定义为以下
var myColumnStateName = function (grid) {
return window.location.pathname + '#' + grid[0].id;
}
的myColumnStateName的使用相应地改变。此外，我扩展了列状态以保存rowNum值。
更新3：The answer描述如何使用新的可能性免费jqGrid保存网格状态。

@安德鲁斯：在我发布的演示中，没有删除，添加或编辑操作。你怎么可以尝试没有例外将被抛出。 – Oleg 2011-12-18 09:03:11
这是一般性评论，对不起。如何在相同和不同的页面中重复使用此代码用于多个网格？这个代码或其他想法可以扩展或分类jqgrid吗？ – Andrus 2011-12-18 10:21:50
