如何为 JSP 中的字符串结果着色？

Question

在我的 jsp 文件中最后 <%=rs.getString("results")%> as results returns 3 个不同的结果作为 W、L 和 D。如何使用 if 条件 and/or 其他语句显示 W 代表绿色，L 代表红色，D 代表黄色？

如果有任何问题，我将代码添加到此 link：https://codeshare.io/EBbOyO

在此先感谢那些愿意提供帮助的人。

    <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>
      <th class="text-center col-xs-1" style="width:5%"  scope="col">Away Score</th>

Answer 1

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

您可以将结果传递给 class，并添加样式

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