Jquery/ javascript : Select all the selected values from drop down

Question

Select box

<select id="update-select" multiple="multiple">
  <option value="3">Test1 </option>
  <option value="4">Test2 </option>
  <option value="5">Test3 /option>
  <option value="6">Test4</option>
  <option value="15">Test5</option>
</select>

I am selecting the options from another jquery click function based on some manipulation .

(say i have selected values 3 and 4)

later i want to see the values of selected option

i tried,

selectedVals = $("#update-select option:selected").val() ;
alert(selectedVals) // alerts 3

it shows only the first value selected.

Any suggestion?

Answer 1

这应该做

selectedVals = $("#update-select").val() ;

Answer 2

You should use:

$("#update-select option:selected").each(function(i,elem){
   alert($(elem).val());
});
