    copied!<p>I have a day &lt;SELECT&gt; field and a month &lt;SELECT&gt; field, and the day &lt;SELECT&gt; should contain the month's days number of &lt;OPTION&gt;s. for exemple if I choose April from month &lt;SELECT&gt; the number of &lt;OPTION&gt;s in the day &lt;SELECT&gt; is 30. My question is: how can I add an &lt;OPTION&gt; field between the &lt;SELECT&gt; and &lt;/SELECT&gt;?</p> <p>this is the HTML code:</p> <pre><code>&lt;div class="input"&gt; &lt;label&gt;Date de naissance&lt;/label&gt; &lt;br&gt; &lt;select name="jour"&gt;&lt;/select&gt; &lt;select name="mois" onchange="ajouterJours(this.options[this.selectedIndex].text);"&gt;&lt;/select&gt; &lt;input type="number" name="annee"&gt; &lt;/div&gt; </code></pre> <p>and this is the JS script I've created so far:</p> <p>his is the function which gonna work on the load of the page :</p> <pre><code>function main() { var i = 0; var moisSelect = form.mois; while (i&lt;12) { i++; moisSelect // here I cant figure out what to do with the month SELECT to add options } } </code></pre> <p>And this is the function which add options between &lt;SELECT&gt; and &lt;/SELECT&gt; for the day &lt;SELECT&gt; field:</p> <pre><code>function ajouterJours(mois) { var mois = 0; var jourSelect = form.jour; switch(mois) { case 1,3,5,7,8,10,12: mois = 31; break; case 2: mois = 29; break; case 4,6,9,11: mois = 30; } var i = 0; while (i&lt;m) { i++; jourSelect // here I cant figure out what to do with the day SELECT to add options } } </code></pre>
