javascript - 通过动态值改变CSS

Question

如果超出动态值，谁可以更改表中列的背景颜色。

这些值由 Nodered 更新。但我找不到合适的javascript方法。

<table>
  <tr>
    <th class="header" colspan="2">HEADER</th>
  </tr>
  <tr>
    <td class="column">{{msg.payload}}</td>
  </tr>
</table>

<script>

    $(".column").change(function(){
        if ({{msg.payload}} >= 6) {
             $(this).css("background-color", "#D6D6FF");
        } else {
            $(this).css("background-color", "#D6D600");
        }
    });

</script>

Answer 1

您的{{msg.payload}}不在 <script></script> 之间
