如果隐藏其中的每一行，则在 jqgrid 中隐藏分组标题

Question

这是 Oleg 已回答的 this question 的延续。

我有 2 个配置文件。

我比较它们是否相等，所以我有两个选项，如图所示（单选按钮）a。查看所有记录，b。查看差异

选项 a。 网格显示所有行，唯一的变化是不相等的值（在 JSON 中由 isEqual=false 标识）它们的颜色不同。

在选项b中。

如果对应的行不相等（在 JSON 中由 isEqual=false 标识），则更改网格中的行颜色并且不显示相等（在 JSON 中由 isEqual=true 标识）的行值（因为这是 option b. 查看差异。所以现在在某些配置（json）中，Product（分组）的所有行都相等（即isEqual=true），所有行都隐藏在这些行之下，我想如果行内的所有行都被隐藏，那么分组也不应该是可见的。

例如：如果Product 分组隐藏了所有行，那么即使Product 分组也应该被隐藏

Answer 1

我建议您稍微更改在loadComplete 处理程序中枚举网格行的方式。我建议以here 描述的方式枚举所有网格行。

具有 'jqgfirstrow' 类的行将仅用于设置列的宽度。应该跳过它。

具有 'jqgroup' 类的行是分组行。行的 id 将由网格 id（<table> 元素的 id）、文本 'ghead_' 和网格参数 groupingView.sortnames[0] 中的索引构成，它们表示组的排序名称。

典型的数据行是具有“jqgrow”类的网格行。您应该检查行数据的isEqual 属性并隐藏或突出显示这些行。

您将找到演示 here，它显示以下结果：

下面我另外填写的loadComplete处理程序的新版本代码

loadComplete: function () {
    var p = this.p, data = p.data, indexes = p._index,
        names = p.groupingView.sortnames[0], iName, idParts,
        rows = this.rows, cRows = rows.length, iRow, $row, rowData,
        previousGrouppigRow = null, hasHighlitedItem = false,
        lastCollaped = false,
        onGroupingExpand = function () {
            var $curRow = $(this).closest("tr.jqgroup").next();
            while ($curRow.hasClass('jqgrow')) {
                rowData = data[indexes[$curRow[0].id]];
                if (rowData.isEqual) {
                    $curRow.hide();
                }
                $curRow = $curRow.next();
            }
        };

    if (this.p.datatype !== 'local') {
        // reload grid to sort it
        setTimeout(function () {
            gridDiff.trigger('reloadGrid');
        }, 0);
        return; //we need not do anything now
    } else {
        parentContainer.show();
    }

    for (iRow = 0; iRow < cRows; iRow += 1) {
        $row = $(rows[iRow]);
        if ($row.hasClass('jqgroup')) {
            $row.find("span.ui-icon").click(onGroupingExpand);

    if (previousGrouppigRow !== null && hasHighlitedItem === false) {
        // the previous grout has no highlited items
        if (!lastCollaped) {
            gridDiff.jqGrid('groupingToggle', previousGrouppigRow[0].id);
        }
        previousGrouppigRow.hide();
    }
}

我建议你另外使用我在my previous answer末尾描述的建议。
