使用javascript根据选择显示/隐藏（切换）div的显示

问题描述：

我有一个带有下拉菜单和两个div的网页，如下所示：

I have a web page with a dropdown menu and two divs as given below:

<html>
<head>
<title>Show/Hide a div section based on selection</title>
</head>
<body>
    <select id='sel'>
    <option value="1">Option 1</option>
    <option value="2">Option 2</option>
    </select>

    <div id="firstdiv">
    <label><input type="checkbox" id='1' />A</label>
    <label><input type="checkbox" id='2' />B</label>
    <label><input type="checkbox" id='3' />C</label>
    </div>

    <div id="seconddiv">
    <label><input type="checkbox" id='4' />D</label>
    <label><input type="checkbox" id='5' />E</label>
    <label><input type="checkbox" id='6' />F</label>
    </div>
</body>
</html>

如何根据使用javascript或jQuery的选择切换上述两个div的显示？即当我选择选项1时，firstdiv应该显示，之后应该隐藏，反之亦然。

How can I toggle the display of the above two divs based on selection using javascript or jQuery? I.e. when I select option 1, the firstdiv should display and later one should hide and vice versa.

HTML

<select id="selectMe">
    <option value="div1">div1</option>
    <option value="div2">div2</option>
</select>
<br><br><br>

 <div id="div1" class="group" >
  <label><input type="checkbox" id='1' />A</label>
<label><input type="checkbox" id='2' />B</label>
<label><input type="checkbox" id='3' />C</label>
</div>

 <div id="div2" class="group" >
  <label><input type="checkbox" id='4' />D</label>
<label><input type="checkbox" id='5' />E</label>
<label><input type="checkbox" id='6' />F</label>
</div>

JS：

$(document).ready(function () {
    $('.group').hide();
    $('#div1').show();
    $('#selectMe').change(function () {
        $('.group').hide();
        $('#'+$(this).val()).show();
    })
});
