单击按钮时，Javascript会隐藏某些表行

我想在单击按钮时隐藏表中的某些行，同时保留某些行。例如，我点击了"Show Fire based champs"按钮。它将只显示具有"火"属性的冠军，并将隐藏其余冠军(从同一张表中(。我点击了另一个名为"显示基于水的冠军"的按钮，该按钮将只显示具有"水"属性的冠军，并隐藏其余的冠军等，其他按钮也是如此。有人能为它编一个代码吗？我对JS没有经验。

以下是主表的外观(只是一个示例，还有更多的表行(。

<table border="1" width="800">
<thead><tr>
    <th>Hero</th>
    <th>Class</th>
    <th>Offensive Skill</th>
    <th>Passive Skill</th>
    <th>Ultimate</th>
</tr></thead>
<tbody>
    <tr><td><a class="holy">Arcana</a></td>
    <td>the Arcane Manipulator</td>
    <td> - </td>
    <td> - </td>
    <td>Arcane Destroyer</td></tr>
    <tr><td><a class="fire">Azakiel</a></td>
    <td>the Blood Mage</td>
    <td> - </td>
    <td>Elf Blood</td>
    <td>Call of the Phoenix</td></tr>
    <tr><td><a class="wind">Bahamut</a></td>
    <td>the King of the Skies</td>
    <td> - </td>
    <td> - </td>
    <td>Mega Flare</td></tr>
    <tr><td><a class="dark">Carinblack</a></td>
    <td>the Dark Assailant</td>
    <td>Sword Bash</td>
    <td> - </td>
    <td>Blade of the Dark</td></tr>
    <tr><td><a class="earth">Dran</a></td>
    <td>the Steel Beast</td>
    <td>Rushing Tackle</td>
    <td> - </td>
    <td>Rolling Thunder</td></tr>
    <tr><td><a class="water">Fenrir</a></td>
    <td>the Water Emperor</td>
    <td>Water Barrage</td>
    <td> - </td>
    <td>Waterfall</td></tr>
    <tr><td><a class="thunder">Larza</a></td>
    <td>the Lightning Heroine</td>
    <td>Staff of Lightning</td>
    <td> - </td>
    <td>Storm Surge</td></tr>
    <tr><td><a class="thunder">Razor</a></td>
    <td>the Thunder Emperor</td>
    <td>Thunder Strike</td>
    <td> - </td>
    <td>Thunderstorm</td></tr>

使用show()和hide()

例如，当点击"显示基于火力的冠军"时，执行：

$('tbody tr').hide() //Hide all rows
$('tbody tr:has(a.fire)').show() //Show all fire rows

这里有一个jsfiddle，里面有所有的代码

HTML代码：

<html><head>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.0b1.js"></script>
<script type="text/javascript">
 function show(champ){
  $('tbody tr').hide()   
  $('tbody tr:has(a.'+champ+')').show()
 }

</script>

</head>
<body>
  <table border="1" width="800">
<thead><tr>
    <th>Hero</th>
    <th>Class</th>
    <th>Offensive Skill</th>
    <th>Passive Skill</th>
    <th>Ultimate</th>
</tr></thead>
<tbody>
    <tr><td><a class="holy">Arcana</a></td>
    <td>the Arcane Manipulator</td>
    <td> - </td>
    <td> - </td>
    <td>Arcane Destroyer</td></tr>
    <tr><td><a class="fire">Azakiel</a></td>
    <td>the Blood Mage</td>
    <td> - </td>
    <td>Elf Blood</td>
    <td>Call of the Phoenix</td></tr>
    <tr><td><a class="wind">Bahamut</a></td>
    <td>the King of the Skies</td>
    <td> - </td>
    <td> - </td>
    <td>Mega Flare</td></tr>
    <tr><td><a class="dark">Carinblack</a></td>
    <td>the Dark Assailant</td>
    <td>Sword Bash</td>
    <td> - </td>
    <td>Blade of the Dark</td></tr>
    <tr><td><a class="earth">Dran</a></td>
    <td>the Steel Beast</td>
    <td>Rushing Tackle</td>
    <td> - </td>
    <td>Rolling Thunder</td></tr>
    <tr><td><a class="water">Fenrir</a></td>
    <td>the Water Emperor</td>
    <td>Water Barrage</td>
    <td> - </td>
    <td>Waterfall</td></tr>
    <tr><td><a class="thunder">Larza</a></td>
    <td>the Lightning Heroine</td>
    <td>Staff of Lightning</td>
    <td> - </td>
    <td>Storm Surge</td></tr>
    <tr><td><a class="thunder">Razor</a></td>
    <td>the Thunder Emperor</td>
    <td>Thunder Strike</td>
