JQGrid - 多选 [英] JQGrid - Multiselect

问题描述

JQGrid 中的多选仅允许多选或单选，并且移位功能不是我期望的移位选择所做的.我也不喜欢我们需要带有多选功能的组合框.

Multiselect in JQGrid only allows either multiple selection or single selections and the shift functionality isn't what I'd expect the shift select to do. I also don't like that we need comboboxes with multiselect.

我还可以为多选使用什么其他解决方案?

What other solution could I use for multiselect?

推荐答案

[2011 年 10 月] 更新为使用 4.0 API，更正了移位选择错误，简化了选择循环.在 4.2.0 中测试.

[Oct 2011] Updated to use 4.0 API, corrected shift-selection bugs, simplified selection loop. Tested in 4.2.0.

如果像我一样，您需要在 jqgrid 中进行适当的多选 - 其中 ctrl 一次选择一行，select 选择多行，既不清除选择，也不选择 1 行 - 您已经找到了.

If like me, you needed a proper multiselect in the jqgrid - where ctrl selects a single row at a time, select selects multiple rows and neither clear the selection and selects 1 row - You've found it.

第一件事:在网格定义中设置 multiselect: true(我没有设置任何其他多选选项)

First things first: set multiselect: true in the grid definition (I didn't set any other multiselect options)

下一步: 在 gridComplete: function () {} 中设置 grid.jqGrid('hideCol', 'cb'); - 这个如果您不想要复选框，请隐藏它们.

Next: In gridComplete: function () {} set grid.jqGrid('hideCol', 'cb'); - this hides the checkboxes if you don't want them.

最后:主要部分

beforeSelectRow: function (rowid, e) {
    if (!e.ctrlKey && !e.shiftKey) {
        $("#grid").jqGrid('resetSelection');
    }
    else if (e.shiftKey) {
        var initialRowSelect = $("#grid").jqGrid('getGridParam', 'selrow');
        $("#grid").jqGrid('resetSelection');

        var CurrentSelectIndex = $("#grid").jqGrid('getInd', rowid);
        var InitialSelectIndex = $("#grid").jqGrid('getInd', initialRowSelect);
        var startID = "";
        var endID = "";
        if (CurrentSelectIndex > InitialSelectIndex) {
            startID = initialRowSelect;
            endID = rowid;
        }
        else {
            startID = rowid;
            endID = initialRowSelect;
        }

        var shouldSelectRow = false;
        $.each($("#grid").getDataIDs(), function(_, id){
            if ((shouldSelectRow = id == startID || shouldSelectRow)){
              $("#grid").jqGrid('setSelection', id, false);
            }
            return id != endID;                        
        });
    }
    return true;
}
