Get value of multiselect box using jQuery or pure JS

Solution 1:

the val function called from the select will return an array if its a multiple. $('select#my_multiselect').val() will return an array of the values for the selected options - you dont need to loop through and get them yourself.

Solution 2:

I think the answer may be easier to understand like this:

$('#empid').on('change',function() {
  alert($(this).val());
  console.log($(this).val());
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<select id="empid" name="empname" multiple="multiple">
  <option value="0">Potato</option>
  <option value="1">Carrot</option>
  <option value="2">Apple</option>
  <option value="3">Raisins</option>
  <option value="4">Peanut</option>
</select>
<br />
Hold CTRL / CMD for selecting multiple fields

If you select "Carrot" and "Raisins" in the list, the output will be "1,3".

Solution 3:

var data=[];
var $el=$("#my-select");
$el.find('option:selected').each(function(){
    data.push({value:$(this).val(),text:$(this).text()});
});
console.log(data)

Solution 4:

According to the widget's page, it should be:

var myDropDownListValues = $("#myDropDownList").multiselect("getChecked").map(function()
{
    return this.value;    
}).get();

It works for me :)

Solution 5:

This got me the value and text of the selected options for the jQuery multiselect.js plugin:

$("#selectBox").multiSelect({
    afterSelect: function(){
        var selections = [];
        $("#selectBox option:selected").each(function(){
            var optionValue = $(this).val();
            var optionText = $(this).text();
            console.log("optionText",optionText);                
            // collect all values
            selections.push(optionValue);
        });

        // use array "selections" here.. 
    }
});   

very usefull if you need it for your "onChange" event ;)
