我有这样的问题，如何更改每一行的背景颜色？

例如我有桌子

为此，我要制作其他颜色，例如红色。

HTML：

    <table>
    <thead>
        <tr>
            <th></th>
            <th>Data</th>
            <th>Data</th>
            <th>Data</th>
            <th>Data</th>
            <th>Data</th>
            <th>Data</th>
            <th>Data</th>
        </tr>
    </thead>
    <tbody class="tableData">
    </tbody>
</table>

JS：

var lpmsData = [
    { item: "111000355B", order: "9999999999", actual: "403", target: "404", defects: "1", efficiency: 89, pefomance: 78, oee: "N/A", startTime: "06:45:44" },
    { item: "102211549B", order: "8888888887", actual: "504", target: "366", defects: "123", efficiency: 125, pefomance: 96, oee: "N/A", startTime: "05:35:64" }
];

var timeShedule = [
    { firstShift: ["05:45 - 07:00", "07:00 - 08:00", "08:00 - 09:00", "09:00 - 10:00", "10:00 - 11:00", "11:00 - 12:00", "12:00 - 13:00", "13:00 - 14:00", "14:00 - 14:45",]}
];

function buildTable() {
    $.each(lpmsData, function (i, data) {
        var categoryBuild = '<tr><td width="150">' + timeShedule[0].firstShift[i] + '</td><td>' + data.item + '</td><td>' + data.actual + '</td><td>' + data.target + '</td><td>' + data.defects + '</td><td>' + data.efficiency + '</td><td>' + data.pefomance + '</td><td>' + data.oee + '</td></tr>';
        if (data.efficiency <= 50) {
            $(this).css("background-color", "blue");
        }
        $('.tableData').append(categoryBuild);
    });

}

我尝试使用这种类型的代码，但已收到：

所以知道怎么做吗？

您可以在if方法之后移动append语句：

$('.tableData').append(categoryBuild);
if (data.efficiency <= 50) {
  $('.tableData tr:last').css("background-color", "blue");
}

演示 

var lpmsData = [{
    item: "111000355B",
    order: "9999999999",

    efficiency: 100,
    pefomance: 78,
    oee: "N/A",
    startTime: "14:36:13"
  }
];

var timeShedule = [{
  firstShift: ["05:45 - 07:00", "07:00 - 08:00", "08:00 - 09:00", "09:00 - 10:00", "10:00 - 11:00", "11:00 - 12:00", "12:00 - 13:00", "13:00 - 14:00", "14:00 - 14:45", ]
}];

buildTable()

function buildTable() {
  $.each(lpmsData, function(i, data) {
    var categoryBuild = '<tr><td width="150">' + timeShedule[0].firstShift[i] + '</td><td>' + data.item + '</td><td>' + data.actual + '</td><td>' + data.target + '</td><td>' + data.defects + '</td><td>' + data.efficiency + '</td><td>' + data.pefomance + '</td><td>' + data.oee + '</td></tr>';
    if (data.efficiency <= 50) {
      categoryBuild = $($.parseHTML(categoryBuild))
      categoryBuild.css("background-color", "blue");
    }
    $('.tableData').append(categoryBuild);
  });

}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<table>
  <thead>
    <tr>
      <th></th>
      <th>Item number</th>
      <th>Actual</th>
      <th>Target</th>
      <th>Defects</th>
      <th>Efficiency</th>
      <th>Performance</th>
      <th>OEE</th>
    </tr>
  </thead>
  <tbody class="tableData">
  </tbody>
</table>

另一种方法是这样：

if (data.efficiency <= 50) {
  categoryBuild = $($.parseHTML(categoryBuild))
  categoryBuild.css("background-color", "blue");
}

您可以使用模板文字并将类添加到tr。<tr class="${data.efficiency<=50?'blue':''}">正在检查data.efficiency的值是否小于或等于50。如果是，则将类添加到{ {1}} 

tr

为什么不只是纯CSS？

 tbody.tableData tr:nth-child(even) {background: red;}
