Question

Using jQuery, how do you check if there is an option selected in a select menu, and if not, assign one of the options as selected.

(The select is generated with a maze of PHP functions in an app I just inherited, so this is a quick fix while I get my head around those 🙂

Answer 1

While I’m not sure about exactly what you want to accomplish, this bit of code worked for me.

<select id='mySelect' multiple='multiple'>   <option value='1'>First</option>   <option value='2'>Second</option>   <option value='3'>Third</option>   <option value='4'>Fourth</option> </select>  <script type='text/javascript'>  $(document).ready(function() {   if (!$('#mySelect option:selected').length) {     $('#mySelect option[value='3']').attr('selected', 'selected');   } }); </script>
