jQuery Get Selected Option From Dropdown


Usually I use $("#id").val() to return the value of the selected option, but this time it doesn't work. The selected tag has the id aioConceptName

html code

<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
    <option>choose io</option>
    <option>roma</option>
    <option>totti</option>
</select>

For dropdown options you probably want something like this:

var conceptName = $('#aioConceptName').find(":selected").text();

The reason val() doesn't do the trick is because clicking an option doesn't change the value of the dropdown--it just adds the :selected property to the selected option which is a child of the dropdown.


Set the values for each of the options

<select id="aioConceptName">
    <option value="0">choose io</option>
    <option value="1">roma</option>
    <option value="2">totti</option>
</select>

$('#aioConceptName').val() didn't work because .val() returns the value attribute. To have it work properly, the value attributes must be set on each <option>.

Now you can call $('#aioConceptName').val() instead of all this :selected voodoo being suggested by others.


I stumbled across this question and developed a more concise version of Elliot BOnneville's answer:

var conceptName = $('#aioConceptName :selected').text();

or generically:

$('#id :pseudoclass')

This saves you an extra jQuery call, selects everything in one shot, and is more clear (my opinion).


Try this for value...

$("select#id_of_select_element option").filter(":selected").val();

or this for text...

$("select#id_of_select_element option").filter(":selected").text();

If you are in event context, in jQuery, you can retrieve the selected option element using :
$(this).find('option:selected') like this :

$('dropdown_selector').change(function() {
    //Use $option (with the "$") to see that the variable is a jQuery object
    var $option = $(this).find('option:selected');
    //Added with the EDIT
    var value = $option.val();//to get content of "value" attrib
    var text = $option.text();//to get <option>Text</option> content
});

Edit

As mentioned by PossessWithin, My answer just answer to the question : How to select selected "Option".

Next, to get the option value, use option.val().


Have you considered using plain old javascript?

var box = document.getElementById('aioConceptName');

conceptName = box.options[box.selectedIndex].text;

See also Getting an option text/value with JavaScript


$('#aioConceptName option:selected').val();

Reading the value (not the text) of a select:

var status = $("#Status").val();
var status = $("#Status")[0].value;
var status = $('#Status option:selected').val();

How to disable a select? in both variants, value can be changed using:

A

User can not interact with the dropdown. And he doesn't know what other options might exists.

$('#Status').prop('disabled', true);

B

User can see the options in the dropdown but all of them are disabled:

$('#Status option').attr('disabled', true);

In this case, $("#Status").val() will only work for jQuery versions smaller than 1.9.0. All other variants will work.

How to update a disabled select?

From code behind you can still update the value in your select. It is disabled only for users:

$("#Status").val(2);

In some cases you might need to fire events:

$("#Status").val(2).change();

you should use this syntax:

var value = $('#Id :selected').val();

So try this Code:

var values = $('#aioConceptName :selected').val();

<select id="form-s" multiple="multiple">
    <option selected>city1</option>
    <option selected value="c2">city2</option>
    <option value="c3">city3</option>
</select>   
<select id="aioConceptName">
    <option value="s1" selected >choose io</option>
    <option value="s2">roma </option>
    <option value="s3">totti</option>
</select>
<select id="test">
    <option value="s4">paloma</option>
    <option value="s5" selected >foo</option>
    <option value="s6">bar</option>
</select>
<script>
$('select').change(function() {
    var a=$(':selected').text(); // "city1city2choose iofoo"
    var b=$(':selected').val();  // "city1" - selects just first query !
    //but..
    var c=$(':selected').map(function(){ // ["city1","city2","choose io","foo"]
        return $(this).text();
    }); 
    var d=$(':selected').map(function(){ // ["city1","c2","s1","s5"]
        return $(this).val();
    });
    console.log(a,b,c,d);
});
</script>

Using jQuery, just add a change event and get selected value or text within that handler.

If you need selected text, please use this code:

$("#aioConceptName").change(function () {
    alert($("#aioConceptName :selected").text())
});

Or if you need selected value, please use this code:

$("#aioConceptName").change(function () {
    alert($("#aioConceptName :selected").attr('value'))
});

Use the jQuery.val() function for select elements, too:

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of select elements, it returns null when no option is selected and an array containing the value of each selected option when there is at least one and it is possible to select more because the multiple attribute is present.

$(function() {
  $("#aioConceptName").on("change", function() {
    $("#debug").text($("#aioConceptName").val());
  }).trigger("change");
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

<select id="aioConceptName">
  <option>choose io</option>
  <option>roma</option>
  <option>totti</option>
</select>
<div id="debug"></div>


For anyone who found out that best answer don't work.

Try to use:

  $( "#aioConceptName option:selected" ).attr("value");

Works for me in recent projects so it is worth to look on it.


Just this should work:

var conceptName = $('#aioConceptName').val();

Straight forward and pretty easy:

Your dropdown

<select id="aioConceptName">
    <option>choose io</option>
    <option>roma</option>
    <option>totti</option>
</select>

Jquery code to get the selected value

$('#aioConceptName').change(function() {
    var $option = $(this).find('option:selected');

    //Added with the EDIT
    var value = $option.val(); //returns the value of the selected option.
    var text = $option.text(); //returns the text of the selected option.
});

use this pattern (syntax):

var value = $('#Id :selected').val();

So replace your variables and try this Code:

var values = $('#aioConceptName :selected').val();

then Enjoy it!


You can try to debug it this way:

console.log($('#aioConceptName option:selected').val())

If you want to grab the 'value' attribute instead of the text node, this will work for you:

var conceptName = $('#aioConceptName').find(":selected").attr('value');

try to this one

$(document).ready(function() {

    $("#name option").filter(function() {
        return $(this).val() == $("#firstname").val();
    }).attr('selected', true);

    $("#name").live("change", function() {

        $("#firstname").val($(this).find("option:selected").attr("value"));
    });
});


<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script>
<select id="name" name="name"> 
<option value="">Please select...</option> 
<option value="Elvis">Elvis</option> 
<option value="Frank">Frank</option> 
<option value="Jim">Jim</option> 
</select>

<input type="text" id="firstname" name="firstname" value="Elvis" readonly="readonly">

$('nameofDropDownList').prop('selectedIndex', whateverNumberasInt);

Imagine the DDL as an array with indexes, you are selecting one index. Choose the one which you want to set it to with your JS.


try this Code:

var values = $('#aioConceptName :selected').val();

For get value of tag selected:

 $('#id_Of_Parent_Selected_Tag').find(":selected").val();

And if you want to get text use this code:

 $('#id_Of_Parent_Selected_Tag').find(":selected").text();

For Example => i have this tag selected :

<div id="i_am_parent_of_select_tag">
<select>
        <option value="1">CR7</option>
        <option value="2">MESSI</option>
</select>
</div>
<script>
 $('#i_am_parent_of_select_tag').find(":selected").val();//OUTPUT:1 OR 2
 $('#i_am_parent_of_select_tag').find(":selected").text();//OUTPUT:CR7 OR MESSI
</script>

I hope this also helps to understand better and helps try this below,

$('select[id="aioConceptName[]"] option:selected').each(function(key,value){
   options2[$(this).val()] = $(this).text();
   console.log(JSON.stringify(options2));
});

to more details please http://www.drtuts.com/get-value-multi-select-dropdown-without-value-attribute-using-jquery/


to fetch a select with same class= name you could do this, to check if a select option is selected.

var bOK = true;
$('.optKategorien').each(function(index,el){
    if($(el).find(":selected").text() == "") {
        bOK = false;
    }
});

to use $("#id").val, You should add a value to the option like this :

<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
    <option value="choose">choose io</option>
</select>

else, You can use

   $("#aioConceptName").find(':selected').text();

I wish that helps ..


Here is the simple solution for this issue.

$("select#aioConceptName").change(function () {
           var selectedaioConceptName = $('#aioConceptName').find(":selected").val();;
           console.log(selectedaioConceptName);
        });

Probably your best bet with this kind of scenario is to use jQuery's change method to find the currently selected value, like so:

$('#aioConceptName').change(function(){

   //get the selected val using jQuery's 'this' method and assign to a var
   var selectedVal = $(this).val();

   //perform the rest of your operations using aforementioned var

});

I prefer this method because you can then perform functions for each selected option in a given select field.

Hope that helps!


You can use $("#drpList").val();


Usually you'd need to not only get the selected value, but also run some action. So why not avoid all the jQuery magic and just pass the selected value as an argument to the action call?

<select onchange="your_action(this.value)">
   <option value='*'>All</option>
   <option ... />
</select>

You can select using exact selected option : Below will give innerText

$("select#aioConceptName > option:selected").text()

While below will give you value.

$("select#aioConceptName > option:selected").val()

I had the same issue and I figured out why it was not working on my case
The html page was divided into different html fragments and I found that I have another input field that carries the same Id of the select, which caused the val() to be always empty
I hope this saves the day for anyone who have similar issue.


Try

aioConceptName.selectedOptions[0].value

let val = aioConceptName.selectedOptions[0].value

console.log('selected value:',val);
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
    <option>choose io</option>
    <option>roma</option>
    <option>totti</option>
</select>
