jqGrid - TreeGrid 交替排序

Question

我有一个工作正常的树形网格。网格对层次结构中的列进行排序，效果很好。但是，我需要能够“打破”树的层次结构并像非树网格那样进行排序。有没有一种方法可以在不加载两个 jqGrid（一个带树形网格，一个不带树形网格）的情况下执行此操作？

当我说我想“打破”层次结构时，我基本上想关闭树形网格并仅将数据加载到普通的非树形网格中。我可以加载两个网格，但我想关闭现有网格中的树形网格。

我正在使用使用本地 json 数据的树形网格：

$('#heatmap').jqGrid({            

        datatype: 'jsonstring',

        datastr: [
{id: "0", initalColumn: "0", 0: "National", 1: "65", 2: "69", 3: "73", 4: "73", 5:     "69", 6: "73", 7: "77", level: "0", parent: "null", isLeaf: false, expanded: true, loaded: true},

我认为您需要做的是将用于 datastr 参数的数组保存在变量中。该变量可用于创建树形网格或“标准”网格。您应该重新创建网格GridUnload 方法，如果你想从树状网格切换到标准网格。在答案中，您将找到演示如何使用的演示网格卸载。
