我想弄清楚为什么此网格一角的字段中的百分比数字设置为NaN。为了节省您的时间，请在这里查看JsFiddle; https://jsfiddle.net/arame3333/ttc83khL/8/

Answer 1

您应该使用{strong>一次调用footerData方法而不是多次调用。首先，它更有效，并且它很重要，因为faultsPerc列的格式化代码使用了outstandingFaults和totalFaults属性的内容em>同一行。 footerData方法有3个参数。如果您未指定false作为最后一个参数，则数据将根据相应列的格式化程序进行格式化。因此，在outstandingFaults中定义totalFaults和footerData属性非常重要。

loadComplete: function() {
  var $grid = $(this);
  var colSumYearStart = $grid.jqGrid('getCol', "yearStart", false, 'sum') / 2;
  var colSumLastMonth = $grid.jqGrid('getCol', "lastMonth", false, 'sum') / 2;
  var colSumThisMonth = $grid.jqGrid('getCol', "thisMonth", false, 'sum') / 2;
  var colSumOutstandingFaults = $grid.jqGrid('getCol', "outstandingFaults", false, 'sum') / 2;
  var colSumOpenFaults = $grid.jqGrid('getCol', "openFaults", false, 'sum') / 2;
  var colSumCloseFaults = $grid.jqGrid('getCol', "closeFaults", false, 'sum') / 2;
  var colSumTotalFaults = $grid.jqGrid('getCol', "totalFaults", false, 'sum') / 2;
  var avePercentage = colSumOutstandingFaults / colSumTotalFaults * 100;
  $grid.jqGrid('footerData', 'set', {
    name: "Total",
    yearStart: colSumYearStart,
    lastMonth: colSumLastMonth,
    thisMonth: colSumThisMonth,
    outstandingFaults: colSumOutstandingFaults,
    openFaults: colSumOpenFaults,
    closeFaults: colSumCloseFaults,
    totalFaults: colSumTotalFaults,
    faultsPerc: avePercentage
  });
}

此外，您可以考虑使用jsonmap代替自定义格式化程序：

{ name: 'faultsPerc', formatter: "currency", width: 80,
    formatoptions: { suffix: "%", decimalPlaces: 0 },
    align: "right", sorttype: "integer",
    searchoptions: { sopt: ["eq", "ne", "lt", "le", "gt", "ge"] },
    jsonmap: function (item) {
        return Math.round(item.outstandingFaults / item.totalFaults * 100);
    }
}

jsonmap将＆＃34;得到＆＃34;输入数据中的faultsPerc属性并将其保存在本地项数据中。然后，您可以使用任何标准格式化程序，例如formatter: "currency"。见https://jsfiddle.net/OlegKi/ttc83khL/9/
