The example in this article describes the method of adding options to selected in js. Share it with everyone for your reference. The specific implementation method is as follows:
<select id="Mmonth">
<option>1</option>
</select>
<input type="button" onclick="a()" value="添加"/>
<script>
function a(){
document.getElementById("Mmonth").options.add(new Option(1,1));
}
</script>I hope this article will be helpful to everyone’s JavaScript programming design.
