推荐答案

使用id更新选择器或使用!important作为样式值，因为具有id的样式具有更高的优先级.

Update the selector with id or use !important with the style value since style with id has the higher priority.

#div1.change{
   background-color:#4A6B4C;
}

$(document).ready(function() {
  $('#div1').click(function() {
    $('#div1').toggleClass('change');
  });
});

#div1 {
  background-color: #33C43C;
  width: 40px;
  height: 40px;
  border-radius: 50%;
  color: white;
  text-align: center;
  font-size: 30px;
}

#div2 {
  text-align: center;
  color: white;
  background-color: #33C43C;
  width: 40px;
  height: 40px;
  border-radius: 50%;
  font-size: 30px;
}

#div1:hover {
  cursor: pointer;
  background-color: #4A6B4C;
}

#div2:hover {
  cursor: pointer;
  background-color: #4A6B4C;
}

#div1.change {
  background-color: #4A6B4C;
}


/* div1 must change to this color */

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="div1" class="op1">
  S
</div>
<br><br>
<div id="div2" class="op">

</div>

.change{
   background-color:#4A6B4C !important;
}

$(document).ready(function() {
  $('#div1').click(function() {
    $('#div1').toggleClass('change');
  });
});

#div1 {
  background-color: #33C43C;
  width: 40px;
  height: 40px;
  border-radius: 50%;
  color: white;
  text-align: center;
  font-size: 30px;
}

#div2 {
  text-align: center;
  color: white;
  background-color: #33C43C;
  width: 40px;
  height: 40px;
  border-radius: 50%;
  font-size: 30px;
}

#div1:hover {
