How to get multiple select box values using jQuery?

Answer 1

Using the .val() function on a multi-select list will return an array of the selected values:

var selectedValues = $('#multipleSelect').val();

and in your html:

<select id="multipleSelect" multiple="multiple">
    <option value="1">Text 1</option>
    <option value="2">Text 2</option>
    <option value="3">Text 3</option>
</select>

Answer 2

jQuery .val()

  var foo = $('#multiple').val(); 

Answer 3

You can also use js map function:

$("#multipleSelect :selected").map(function(i, el) {
    return $(el).val();
}).get();

And then you can get any property of the option element:

return $(el).text();
return $(el).data("mydata");
return $(el).prop("disabled");
etc...

Answer 4

var selected=[];
 $('#multipleSelect :selected').each(function(){
     selected[$(this).val()]=$(this).text();
    });
console.log(selected);

Yet another approch to this problem. The selected array will have the indexes as the option values and the each array item will have the text as its value.

for example

<select id="multipleSelect" multiple="multiple">
    <option value="abc">Text 1</option>
    <option value="def">Text 2</option>
    <option value="ghi">Text 3</option>
</select>

if say option 1 and 2 are selected.

the selected array will be :

selected['abc']=1; 
selected['def']=2.

Answer 5

Just by one line-

var select_button_text = $('#SelectQButton option:selected')
                .toArray().map(item => item.text);

Output: ["text1", "text2"]

var select_button_text = $('#SelectQButton option:selected')
                .toArray().map(item => item.value);

Output: ["value1", "value2"]

If you use .join()

var select_button_text = $('#SelectQButton option:selected')
                .toArray().map(item => item.text).join();

Output: text1,text2,text3

Answer 6

Html Code:

 <select id="multiple" multiple="multiple" name="multiple">
  <option value=""> -- Select -- </option>
  <option value="1">Opt1</option>
  <option value="2">Opt2</option>
  <option value="3">Opt3</option>
  <option value="4">Opt4</option>
  <option value="5">Opt5</option>
 </select>   

JQuery Code:

$('#multiple :selected').each(function(i, sel){ 
    alert( $(sel).val() ); 

});

Hope it works

Answer 7

Just use this

$('#multipleSelect').change(function() {
    var selectedValues = $(this).val();  
});

Answer 8

Get selected values in comma separator

var Accessids = "";
$(".multi_select .btn-group>ul>li input:checked").each(function(i,obj)
{
    Accessids=Accessids+$(obj).val()+",";
});
Accessids = Accessids.substring(0,Accessids.length - 1);
console.log(Accessids);

Answer 9

In case if you have multiple select boxes on a single page and they all have the same class which you can prefer in case of multiple rather than tracking id's:

$('.classname option:selected').map(function(){
    return this.value; // If you want value.
    // Or you could also do.
    return this.text; // If you want text of select boxes.
}).get(); // It will return an Array of selected values/texts.
