Question

所以我在顶部有一个无线电组，它将值输出到一个范围......然后我有颜色样本，它将输入（或跨度）中的总和相加。我想要做的是，如果它超过单选按钮值，则将文本的颜色更改为粗体红色。它是动态更新，但我想知道我是否可以使用php if语句来更改样式。这是该页面的代码。

Answer 1

问题：

我想要做的是，如果超过单选按钮值，则将文本的颜色更改为粗体红色。

忽略OP代码的所有错误......

...我们可以向.colorBlock的父.colorDiv添加一个事件监听器。
当用户在.colorBlock > input中的任何一个中输入任意数字时，keyup会触发.colorDiv个事件。
#ttlQty的值和#result的文字被解析为数字......
...并进行比较。如果#ttlQty（count）的值大于#result（quantity）的值...
... #ttlQty颜色会变红......
...否则它的颜色是黑色。

在myFunction功能下添加以下代码：

    var rainbow = document.querySelector('.colorDiv');

    rainbow.addEventListener('keyup', function(event) {
      var count = document.getElementById('ttlQty').value;
      var quantity = document.getElementById('result').textContent;
      if (parseFloat(count) > parseFloat(quantity)) {
        document.getElementById('ttlQty').style.color = 'red';
      }
      else {
        document.getElementById('ttlQty').style.color = 'black';
      }
    }, false);

Answer 2

所以，@ zer00one，这完全奏效了。谢谢！..现在我想知道比jsut更多的样式字体颜色。喜欢背景/高亮颜色和字体颜色。我在想..

<script>
    function myFunction(packSize) {
      document.getElementById("result").innerHTML = packSize;
    }
    var rainbow = document.querySelector('.colorDiv');

    rainbow.addEventListener('keyup', function(event) {
      var count = document.getElementById('ttlQty').value;
      var quantity = document.getElementById('result').textContent;
      if (parseFloat(count) > parseFloat(quantity)) {
        document.getElementById('ttlQty2').style.color = 'white';
        document.getElementById('ttlQty2').style.background-color = 'red';
      } else {
        document.getElementById('ttlQty2').style.color = 'black';
      }
    }, false);
  </script>
