javascript - 根据条件改变列表元素的颜色

Question

我有两张 table :

表1(总分)

表2(每周得分)

我有一个排行榜，我在其中呼应表 1 中的总体得分值:

问题:我在这里想做的是，无论谁在表 2(每周得分)中得分为“-10”，我都想通过突出显示其框的颜色来提醒用户排行榜，现在是黄色，变为红色。

当前涉及的CSS:

li mark div {
    display: block;
    margin: 4px;
    padding: 5px;
    min-height: 50px;
    border: 2px solid #eebb55;
    border-radius: 7pt;
    background: grey;
}

涉及显示列表的 Php。这用于“总体”(排行榜中的右侧选项卡)。类似的每周也存在。

<div id="overalllb" class="leadboardcontent" style="display:none">
    <div class="leaderboard">
        <ol>
            <li>
                <mark>
                    <?php  while( $toprow2 = sqlsrv_fetch_array( $stmt3) ) {
                        echo  "<div class='parent-div'><span class='rank'>" . $toprow2['overallRank'] . "</span><span class='name'>" . $toprow2['EmployeeName'] . "</span><span class='points'>" . $toprow2['Total_points_Rewarded'] . "</span></div>";
                    } ?>
                </mark>
            </li>
        </ol>
    </div>

传递查询以从两个表中检索信息:

1.query 1 - 找出所有得分为-10的员工。

$q200 = " select *
  from Table2
  where  WeekNumber = 'week1' and pointsRewarded = '-10';";
  $stmt200=sqlsrv_query($conn,$q200);
  if($stmt200==false)
  {
  echo 'error to retrieve info !! <br/>';
  die(print_r(sqlsrv_errors(),TRUE));
  }

查询 2- 从表 1 中检索所有员工:

$q20 = "select *
  from EmployeeTable
  order by Total_points_Rewarded desc";
  $stmt20=sqlsrv_query($conn,$q20);
  if($stmt20==false)
  {
  echo 'error to retrieve info !! <br/>';
  die(print_r(sqlsrv_errors(),TRUE));
  }

我尝试使用的代码:

<?php while( $toprow20 = sqlsrv_fetch_array( $stmt20) ) {

echo  "<div class='parent-divv'><span class='rank'>" . $toprow20['overallRank'] . "</span><span class='name'>" . $toprow20['EmployeeName'] . "</span><span class='points'>" . $toprow20['Total_points_Rewarded'] . "</span></div>";

}?>
<?php if ($toprow20['EmployeeID'] == $toprow200['EmployeeID'] ) ?>{
  <style>
  .parent-divv {
  border: 1px solid red;
  }
  </style>
}

上面的代码将所有颜色更改为红色。我只希望两个查询中匹配的名称/ID 为红色。其余保持原样。 我正在使用 PHP，请建议我一种方法。上帝保佑。

Answer 1

1) 将查询合并为一个

select EmployeeTable.*,Table2.pointsRewarded as `weeklyDelta`
from EmployeeTable join Table2 on EmployeeTable.EmployeeID = Table2.EmployeeID
where Table2.WeekNumber = 'week1'
order by Total_points_Rewarded desc

2)然后给负增量的员工一个特殊的类别

<?php  
while( $toprow2 = sqlsrv_fetch_array( $stmt3) ) {
    echo  "<div class='parent-div" .
        ($toprow2['weeklyDelta'] <= -10 ? " dropped" : "") .
        "'><span class='rank'>" .
        $toprow2['overallRank'] . "</span><span class='name'>" . 
        $toprow2['EmployeeName'] . "</span><span class='points'>" . 
        $toprow2['Total_points_Rewarded'] . "</span></div>";
} ?>

3)给这些员工一种风格

.parent-div.dropped { color:red }
