I’m using the following and it works, but the alerted value opt3
contains commas.
How do I remove them?
form method='get' action='form.php'> <select name='val' class='select' id='opt1' multiple> <option></option> <option value='a'>a</option> <option value='b'>b</option> <option value='c'>c</option> <option value='d'>d</option> </select> <select name='opt' id='opt2'> <option value='AAA'>AAA</option> <option value='BBB'>BBB</option> </select> <input type='submit' name='submit' value='submit' onClick="return function1();"> </form> <script type='text/javascript'> function function1(){ var opt1=document.getElementById("opt1").value; var opt2=document.getElementById("opt2").value; var opt3=$('#opt1').val(); alert( opt3 ); var response=confirm("Are you sure? option1="+opt1+" option2="+opt2+" option3="+opt3 ); return response; }
If I select a c & d the alert shows a,c,d but I want it to show acd.

What about this?
var opt3=$('#opt1').val().replace(",","");
Update:
Ok. Like @jreziga mentioned. The return value of .val()
will be an array. If you have a string the upper code example will do just fine.
If you have an array like in your case you can do this:
var opt3=$('#opt1').val().join("");
