在表格中有单词“ CRITICAL”和“ SAFE”,我想计算一下表格中有多少CRITICAL。并且,请不要添加类名或ID名称。

<table>
<tr>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
 <td>SAFE</td>
</tr>
<tr>
 <td>SAFE</td>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
</tr>
</table>

var test = $('td:contains(CRTICAL)');

console.log(test.size());
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
<table>
<tr>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
 <td>SAFE</td>
</tr>
<tr>
 <td>SAFE</td>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
 <td>CRTICAL</td>
</tr>
