Jquery选择器具有多个类和相同的类名

Question

在下面的HTML中，每个都有一个span（class =“flip”）和div（class =“panel”）。 我想编写一个Jquery脚本，当单击一个特定的“Click Here”时，该特定元素的子元素会显示，再次单击它时会隐藏它。

<tbody>
<tr class="even">
    <td>
        <a href="something">
            1
        </a>
        <span class="flip"> Click Here
            <div class="panel" style="display: none;">Hello world!</div>
        </span>
    </td>
</tr>        
<tr class="odd">
    <td>
        <a href="something">
            2
        </a>
        <span class="flip"> Click Here
            <div class="panel" style="display: none;">Hello world!</div>
        </span>
    </td>
</tr>
<tr class="even">
    <td>
        <a href="something">
            a
        </a>
        <span class="flip"> Click Here
            <div class="panel" style="display: none;">Hello world!</div>
        </span>
    </td>    
</tr>
<tr class="odd">
    <td>
        <a href="something">
            Glen Test
        </a>
        <span class="flip"> Click Here
            <div class="panel" style="display: none;">Hello world!</div>
        </span>
    </td>
</tr>

$(document).ready(function() {
    $('.flip').on('click', function() {
        $(this).find('.panel').toggle();
    });
});
