Javascript - verify the values of fields with dynamic names
<p>I have a set of text fields qty with dynamic names: like <code>qty541</code> ; <code>qty542</code> ; <code>qty957</code>
formed by the word: <code>"qty"</code> and the <code>product id</code></p>

<p>How can I verify if all my qty fields are empty or not with Javascript ?</p>

<p>Thanks a lot.</p>
