我一直使用this post作为我的代码的基础，允许通过单击“保存”按钮来保存网格的状态，并通过单击“加载”按钮加载。
我几乎正常工作，因为它正在保存并重新加载任何过滤器数据，但是如果我更改任何列的顺序或可见性，则单击保存按钮时不会保存这些更改。
我不理解源代码中的这条评论
// filterToolbar文本输入的ID是＆＃34; gs _＆＃34; + colModel.name
if(col_arr[i].search && $("#gs_" + col_arr[i].name).val().length)
{
toolbar_search_array.push({ name: col_arr[i].name, value: $("#gs_" + col_arr[i].name).val() });
}
因此，单击“保存”时出现控制台错误。如果我对此部分发表评论，那么我可以保存过滤条件而不需要列顺序和可见性。
以下是我的代码的工作示例。

The answer已经过时了。您包含的代码片段来自refreshSerchingToolbar函数，这不再需要，因为免费的jqGrid 4.13.5应该自动填充过滤器工具栏的输入/选择元素（请参阅the answer）。您没有发布完整的工作演示，但我无法向您指出代码中的确切更改，但您只需从refreshSerchingToolbar删除不需要的loadComplete来电并删除代码函数refreshSerchingToolbar。
关于其他问题：我无法通过the demo保存/恢复可见性或列顺序来重现任何问题。如果确实存在某些问题，请描述确切的测试用例。
