Question

我编写了以下代码来创建pivot grid以显示有关汽车的销售信息。它应该生成一个类似于图像上网格的网格结构

var data = [{
        "id": 1,
        "make": "toyota",
        "model": "corolla",
        "fuelusagecity": "17",
        "fuelusagehwy": "12",
        "fuelmeasure":'Litre',
        "salesaboveavg": false,
        "totalnumberofsales": 120000.0000,
        "highsalestext": null,
        "salesdate": "2010-12-01"
    }, {
        "id": 2,
        "make": "toyota",
        "model": "corolla",
        "fuelusagecity": "10",
        "fuelusagehwy": "14",
        "salesaboveavg": false,
        "fuelmeasure":'Litre',
        "totalnumberofsales": 100000.0000,
        "highsalestext": "HIGH",
        "salesdate": "2010-12-15"
    }, {
        "id": 3,
        "make": "toyota",
        "model": "belta",
        "fuelusagecity": "15",

        "highsalestext": null,
        "salesdate": "2011-01-10"
    }, {
        "id": 4,

            item.salesDay = dateParts[2];
            item.salesDateFormatted = dateParts[0];
        }
    }

    var myIntTemplate = {
        formatter: "currency",

                ],
                aggregates: [{
                    member: "totalnumberofsales",
                    template: myIntTemplate,

                            var items = rawObject.pivotInfos[cm.name];
                            if (items != null && items.rows != null && items.rows.length > 0) {
                                var isHigh = true, i;

                            }
                        }
                    },
                    aggregator: "max"
                }/*,
                 {

                 //template: "integer",
                 label: "{0}"
                 }*/]
            },
            // grid options
            {
                iconSet: "fontAwesome",
                cmTemplate: { autoResizable: true, width: 75 },
                shrinkToFit: false,
                useUnformattedDataForCellAttr: false,
                autoResizing: { compact: true },
                groupingView: {
                    groupField: ["x0"],
                    groupColumnShow: [false],
                    groupText: ["<span class='group-text'>{0}</span>"]
                },
                //width: 450,
                pager: true,
                rowNum: 20,
                //caption: "<b>Car sales statistics</b>",
                rowList: [5, 10, 20, 100, "10000:All"]
            }
    );

    jQuery("#list483").jqGrid('setGroupHeaders', {
  useColSpanStyle: true, 
  groupHeaders:[
    {startColumnName: 'make', numberOfColumns: 3, titleText: '<div style="display:inline-block">Min: <input type="text" id="minDate"  /> Max: <input type="text" id="miaxDate"  /></div>'}
    //{startColumnName: 'closed', numberOfColumns: 2, titleText: 'Shiping'}
  ] 
});

可在此Fiddle code中找到完整的代码。但是，当我应用代码使用以下代码行对列标题进行分组时：

jQuery("#list483").jqGrid('setGroupHeaders', {
  useColSpanStyle: true, 
  groupHeaders:[
    {startColumnName: 'make', numberOfColumns: 3, titleText: '<div style="display:inline-block">Min: <input type="text" id="minDate"  /> Max: <input type="text" id="miaxDate"  /></div>'}
    //{startColumnName: 'closed', numberOfColumns: 2, titleText: 'Shiping'}
  ] 
});

它不按预期对列进行分组。为什么会这样，我该如何解决这个问题？

祝你们新年快乐！

在我看来，列分组在你的情况下并不正确。我建议您在网格选项中添加toolbar: [true, "top"]选项，以在网格顶部创建一个空工具栏。工具栏将具有id来自"t_"前缀的构建和网格的ID。因此，您可以使用下面的代码

将任何自定义内容添加到工具栏

$('<div style="display:inline-block">Min: <input type="text" id="minDate"  /> Max: <input type="text" id="miaxDate"  /></div>').appendTo("#t_list483");
