如何配置此JQGrid列定义，以便对列表框条目'" display&"进行排序.值，而不是& quot;键& quot;值价值?

问题描述

我有一个可编辑的列定义，看起来像这样...

I have an editable column definition that looks like this...

    {
        name: 'recType',
        label: 'recType',
        index: 'recType',
        width: 100,
        fixed: true,
        keys:  true,
        editable: true,
        edittype: "select",
        editoptions: {value: rectypelist},
        stype: 'select',
        formatter: 'select'
    }

注意:"rectypelist"是 key:value 对的列表...例如

Note: "rectypelist" is a list of key:value pairs...e.g.,

    1:apple
    4:pear
    2:orange
    3:banana

我需要能够通过列表框条目的值(即已经正确显示在该列中)对该列进行排序.

I need to be able to sort this column by the listbox entry's value (i.e., which is already correctly displayed in the column).

根据上面的配置，排序是根据列表框条目的键"而不是条目的值"(条目的值"实际上是在网格中显示的)执行的.

As it is configured, above, the sort is performed upon the listbox entry's "key", rather than the entry's "value" (the entry's "value" is what actually displays in the grid).

-因此，当用户对列进行排序时，他们没有收到预期的行为.

-So, therefore, when the user sorts the column they do not received the expected behavior.

问题::如何配置此列定义，以便对列表框条目的显示"值而不是键"值进行排序?

QUESTION: How can I configure this column definition so that the sort is performed on the listbox entry's "display" value, rather than the "key" value?

推荐答案

这是我解决问题的方法...

好吧，很显然，当您将列定义为下拉列表/列表框(包含键:值对的行)...

Here's how I solved the issue...

Well, apparently when your column is defined as dropdown/listbox (containing rows of key:value pairs)...

喜欢

    1:rectypeA
    4:rectypeB
    2:rectypeC
    3:rectypeD

...然后，在列定义中，您需要为"sorttype"参数分配一个函数，该函数将返回您要对之排序的值... (在这种情况下，我想使用"键:值"对中的值") ...

...then, in the column definition, you need assign a function to the "sorttype" parameter that will return the value you want to sort on... (in this case I want to use the "value" from the "key:value" pair)...

-因为我 不 希望我的列按"键" 排序(即，这是问题所在我正在尝试解决！)，显然我必须使用一个函数来返回与键"相对应的"值".

--Since I don't want my column sorted by the "key" (i.e., this is the problem I am trying to solve!), I apparently have to use a function to return the "value" that corresponds to the "key".

在下面的示例中，我创建了一个名为"rectypes"的映射，其中包含 key:value 对.

In the example, below, I've created a map called "rectypes" that contains key:value pairs.

-在函数中，我仅使用"rectypes"映射来提取并返回要在排序中使用的值(与"key"关联)

--In the function, I simply use the "rectypes" map to extract and return the value (associated with the "key") that I want used in the sort

即

    -
    -
    -
    {
        name: 'recType',
        label: 'recType',
        index: 'recType',
        width: 100,
        fixed: true,
        keys:   true,
        sortable:true,
        //...the function below returns the VALUE of
        //   the KEY:VALUE pair that is to be used for the sort
        sorttype: function (cellvalue ) {return rectypes[cellvalue];},
        editable: true,
        edittype: "select",
        editoptions: {value: rectypelist},
        stype: 'select',
        formatter: 'select'
    },
    -
    -
    -

注意:单元值"是自动提供的.在示例中，我创建了一个名为"rectypes"的映射，其中包含"key:value"对，这使我可以提取并返回要用于排序的值.

NOTE: "cellvalue" is supplied auto-magically. In the example I created a map called "rectypes" containing the "key:value" pairs that make it possible for me to extract and return the value that I want to be used for sorting.
