HTML5 Form Pattern for 7 or 10 numbers only
<p>I need a pattern for a student ID that must be either 7 or 10 digits long. </p>

<pre><code>pattern="[0-9]{7,10}"
</code></pre>

<p>I got this but obviously this is between 7-10 not 7 | 10</p>

<p>I tried <code>pattern="[0-9]{7|10}"</code>, that also does not work.</p>

<p>Any ideas?</p>
