javascript - jQuery - 选择具有特定 html 的元素

Question

我尝试选择一个具有特定 html 的 div。看我的例子:

$("#clickMe").click(function(){
    $("div:contains('heinrich')").css("background-color", "limegreen")
});

.normal {
    width: 100px;
    height: 100px;
    display: inline-block;
}
.red {
  background-color: red;
  border: 1px solid black;

}
.blue {
  background-color: blue;
  border: 1px solid black;
}
.yellow {
  background-color: yellow;
  border: 1px solid black;
}

#masterdiv {
  border: 10px solid gray;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="masterdiv">
 My favorite frends are:
   <div class="red normal" id="div1">
       hans
   </div>
    <div class="blue normal" id="div2">
       franz
   </div>
    <div class="yellow normal" id="div3">
       heinrich
   </div>
</div>

<button id="clickMe">
Clicking me should make only heinrichs div limegreen
</button>

但是，父 div 的颜色也会发生变化。有没有办法只选择元素本身，我不允许使用 ID。

最好在选择器中提及 className $("div .normal:contains('heinrich')")

$("#clickMe").click(function(){
    $("div .normal:contains('heinrich')").css("background-color", "limegreen")
});

.normal {
    width: 100px;
    height: 100px;
    display: inline-block;
}
.red {
  background-color: red;
  border: 1px solid black;

}
.blue {
  background-color: blue;
  border: 1px solid black;
}
.yellow {
  background-color: yellow;
  border: 1px solid black;
}

#masterdiv {
  border: 10px solid gray;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="masterdiv">
 My favorite frends are:
   <div class="red normal" id="div1">
       hans
   </div>
    <div class="blue normal" id="div2">
       franz
   </div>
    <div class="yellow normal" id="div3">
       heinrich
   </div>
</div>

<button id="clickMe">
Clicking me should make only heinrichs div limegreen
</button>
