javascript - form validation for at least on select-option is selected -


my form layout similar below:

<form action='' method="post" id='myform'>     <select name='select1'>         <option value=''>select option</select>         <option value='a'> </option>         <option value='b'> b </option>         <option value='c'> c </option>     </select>     <select name='select2'>     <option value=''>select option</select>     <option value='e'> e </option>     <option value='f'> f </option>     <option value='g'> g </option> </select>     <select name='select3'>         <option value=''>select option</select>         <option value='h'> h </option>         <option value='i'> </option>         <option value='j'> j </option>     </select> </form>  <script> $('#myform').validate(); </script>

note: have included jquery.js , jquery.validate.js files.

here, 3 select-option in form. need validate @ least 1 select-option only.

function selectvalidate() {     var check = false;     $.each($('select'), function(index, data) {          if (data.val() !== ''){               check = true;          }     });     return check; }
