如何在JSP中為字串結果著色？

在最后一個<%=rs.getString("results")%>下面的我的 jsp 檔案中，結果回傳 3 個不同的結果，分別為 W、L 和 D。如何使用 if 顯示綠色的 W、紅色的 L 和黃色的 D條件和/或其他宣告？

如果有任何問題，我在此鏈接中添加了代碼：https ://codeshare.io/EBbOyO

提前感謝那些愿意提供幫助的人。

    <table class="table ">
  <thead>
    <tr class="d-flex">
      <th class="text-center col-xs-1" style="width:1%" scope="col">Week</th>
      <th class="text-center col-xs-1"  scope="col">Match Date</th>
      <th  class="text-left  col-xs-1" scope="col">Home</th>
      <th  class="text-left  col-xs-1" scope="col">Away</th>
      <th class="text-center col-xs-1" style="width:5%"  scope="col">Home Score</th>

uj5u.com熱心網友回復：

<span class='label label-success color-<%=rs.getString("results")%>'><%=rs.getString("results")%></span>

您可以將結果傳遞給類，并添加樣式

<style>
.color-W{
color:green;
}
.color-L{
color:red;
}
.color-D{
color:yellow;
}
</style>
