Regex with one or more letters followed with optional digits with total length minimum 8?
<p>I am using pattern in HTML5 validation.
I want a regex to check for such username format:</p>

<pre><code>&lt;letters+&gt;&lt;digits*&gt; : total length minimum 8
-&gt; starting with letters then optional digits.
</code></pre>

<p>examples: w1234567, qweqr123, jsgwiuegn1274124, qwerasdf, awdjwuadhuf, etc.</p>

<p>wrong examples: 12345678, qwe12qwe, 12qweqwe, qweq12, etc.</p>

<p>I tried <code>([A-z]+[0-9]*){8,}</code>, It's not working as expected.</p>
