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 for="name">Name</label>
<input type="text" name="name" id="name" />
<label for="aioConceptName">AIO Concept Name</label>
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
For dropdown options you probably want something like this:
For selected text
var conceptName = $('#aioConceptName').find(":selected").text();
For selected value
var conceptName = $('#aioConceptName').find(":selected").val();
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
<label for="aioConceptName">AIO Concept Name</label>
<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();
For good practice you need to use val() to get value of selected options not text().
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
<option value="choose">choose io</option>
</select>
You can use
$("#aioConceptName").find(':selected').val();
Or
$("#aioConceptName :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();
With JQuery:
If you want to get the selected option text, you can use $(select element).text().
var text = $('#aioConceptName option:selected').text();
If you want to get selected option value, you can use $(select element).val().
var val = $('#aioConceptName option:selected').val();
Make sure to set value attribute in <option> tag, like:
<select id="aioConceptName">
<option value="">choose io</option>
<option value="roma(value)">roma(text)</option>
<option value="totti(value)">totti(text)</option>
</select>
With this HTML code sample, assuming last option is selected:
var text will give you totti(text)
var val will give you totti(value)
$(document).on('change','#aioConceptName' ,function(){
var val = $('#aioConceptName option:selected').val();
var text = $('#aioConceptName option:selected').text();
$('.result').text("Select Value = " + val);
$('.result').append("<br>Select Text = " + text);
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="aioConceptName">
<option value="io(value)">choose io</option>
<option value="roma(value)">roma(text)</option>
<option value="totti(value)">totti(text)</option>
</select>
<p class="result"></p>
you should use this syntax:
var value = $('#Id :selected').val();
So try this Code:
var values = $('#aioConceptName :selected').val();
you can test in Fiddle: http://jsfiddle.net/PJT6r/9/
see about this answer in this post
to find correct selections with jQuery consider multiple selections can be available in html trees and confuse your expected output.
(:selected).val() or (:selected).text() will not work correct on multiple select options. So we keep an array of all selections first like .map() could do and then return the desired argument or text.
The following example illustrates those problems and offers a better approach
<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>
see the different bug prone output in variant a, b compared to correctly working c & d that keep all selections in an array and then return what you look for.
Just this should work:
var conceptName = $('#aioConceptName').val();
$(function() {
$('#aioConceptName').on('change', function(event) {
console.log(event.type + " event with:", $(this).val());
$(this).prev('input').val($(this).val());
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>Name</label>
<input type="text" name="name" />
<select id="aioConceptName">
<option>choose io</option>
<option>roma</option>
<option>totti</option>
</select>
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'))
});
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.
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>
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.
});
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:
<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
$('#i_am_parent_of_select_tag').find(":selected").text();//OUTPUT:CR7 OR MESSI
</script>
You can try to debug it this way:
console.log($('#aioConceptName option:selected').val())
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));
});

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');
Here is the simple solution for this issue.
$("select#aioConceptName").change(function () {
var selectedaioConceptName = $('#aioConceptName').find(":selected").val();;
console.log(selectedaioConceptName);
});
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.
You can use $("#drpList").val();
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;
}
});
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>
There is only one correct way to find selected option - by option value attribute. So take the simple code:
//find selected option
$select = $("#mySelect");
$selectedOption = $select.find( "option[value=" + $select.val() + "]" );
//get selected option text
console.log( $selectedOption.text() );
So if you have list like this:
<select id="#mySelect" >
<option value="value1" >First option</option>
<option value="value2" >Second option</option>
<option value="value3" selected >Third option</option>
</select>
If you use selected attribute for option, then find(":selected") will give incorrect result because selected attribute will stay at option forever, even user selects another option.
Even if user will selects first or second option, the result of $("select option:selected") will give two elements! So $("select :selected").text() will give a result like "First option Third option"
So use value attribute selector and don't forget to set value attribute for all options!
You many try this:
var ioConceptName = $('#ioConceptName option:selected').text();
I have this sample:
link
CODE HTML:
<select name="card_type" id="card_type" class="card-sel com-c select-full">
<option value="visa">Visa</option>
<option value="mastercard">Mastercard</option>
<option value="discovery">Discovery</option>
<option value="maestro">Maestro</option>
</select>
CODE JS:
$( document ).ready(function() {
var stateSelectValue = "Mastercard"; //this value in my site returns a dynamic type of card
console.log("primul log" + stateSelectValue);
if(stateSelectValue)
{
console.log("al doilea log" + stateSelectValue); $("#card_type").val(stateSelectValue).attr("selected","selected").trigger("change");
console.log("al treilea log" + stateSelectValue);
}
$( ".com-c" ).change(function() {
var data= $(this).val();
console.log(data);
});
});
Perhaps the example understand what they want to do.
Basically when they are receiving a value in the variable stateSelectValue to look if there is value in that list and make selected.
For example IF:
var stateSelectValue = "Mastercard";
then
<option value="mastercard" selected="selected">Mastercard</option>
and so on...
Can you help me to solve this problem please?
Thanks in advance!
First as I have already commented, you do not need to set attribute selected and trigger change function.
$("#card_type").val(stateSelectValue)
This should be enough.
Second, if you do this change, still it will not work. W
Why?:
Variable value:
var stateSelectValue = "Mastercard";
is not equal to value of option
<option value="mastercard">Mastercard</option>
Updated Codepen
You were all good just one typo mistake, your selected value was in capital i.e "Mastercard" where as in option value it was "mastercard". But in simple way doing below was enough without trigger change event.
var stateSelectValue = "mastercard";
$("#card_type").val(stateSelectValue)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<select name="card_type" id="card_type" class="card-sel com-c select-full">
<option value="visa">Visa</option>
<option value="mastercard">Mastercard</option>
<option value="discovery">Discovery</option>
<option value="maestro">Maestro</option>
</select>
This question already asked some . please refers the below link:
JQuery setting the selected attribute on a select list
$(document).ready(function () {
$('#card_type').val("mastercard"); // Select by value
text1 = "Maestro";
$("#card_type option:contains(" + text1 + ")").attr('selected', 'selected'); // select by text
});

Get selected value of a dropdown's item using jQuery
(31 answers)
Closed 8 years ago.
I have this <select>:
<select id="week" multiple="multiple" >
<option value="1">Monday</option>
<option value="2">Tuesday</option>
<option value="3">Wednesday</option>
<option value="4">Thursday</option>
<option value="5">Friday</option>
<option value="6">Saturday</option>
<option value="7">Sunday</option>
</select>
How can I know that whether each <option> is selected or not in jQuery or JS?
Try to use :selected selector to grab the selected option elements,
$('#week option:selected').each(function(){
//Your code to manipulate things over selected option elements
});
You need to use .is :
$('#week option').each(function() {
if($(this).is(':selected')){
//code
}
});
You can use length property of selected and total options, see below jquery :
var totalOptions = $('#week option').length; // all options available
var selectedOptions = $('#week option:selected').length;// selected options
if(totalOptions == selectedOptions)
alert('All options selected');
else
alert('Not all options selected');
I'm using .val() in jQuery to retain the value of an options menu onChange.
How would I retain the number (as in as it is ordered) of the item in the drop down using jQuery?
<select>
<option> //option 1
<option> //option 2
</select>
Here is what I have set up now:
<select id="start_month" onChange="getMonthDay()">
<option>Jan</option>
<option>Feb</option>
<option>March</option>
<option>April</option>
<select>
Using,
function getMonthDay()
{
$('#start_month').val()
}
I can get whatever value is selected, but my question is how do I get the Number down of this value in the markup? For March, I would want 3.. and so on
Can you reformulate your question better? I'm still lost in what do you want.
But, nevertheless here is how <select> works in jQuery
<select id="selection">
<option value="val_1">value 1</option>
<option value="val_2">value 2</option>
</select>
$("#selection").val() will give you val_1 or val_2 depending on witch item is currently selected.
If you want to go through all options and check the selected on, you can use
$("#selection option:selected").val();
or itenerate through all <option>'s
$("#selection option").each(function() {
if( $(this).is(":selected") ) {
var v = $(this).val();
}
});
If you want to retain all options you can easily clone them or assign them as data, if you want to keep those values throughout the pages, use Local Database or Cookies to persist the data.
To answer your question after your update:
First: Why don't you have:
<select id="start_month" onChange="getMonthDay()">
<option value="1">Jan</option>
<option value="2">Feb</option>
<option value="3">March</option>
<option value="4">April</option>
<select>
And use the value of the selected item?
Second: Just use what I wrote above and itenerate through the options
$("#start_month option").each(function(index, element) {
if( $(this).is(":selected") ) {
// get index position, remember to add 1 as arrays start at 0
var n = index;
// break each
return false;
}
});
You'd get a list of the <option> elements, find the selected one, and use index:
var $opts = $('#start_month option');
var zero_based_index = $opts.index($opts.filter(':selected'));
Demo: http://jsfiddle.net/ambiguous/HyukW/
Just add 1 if you want a one-based index.
I made something like this,with zero based key ;
<select id='deneme'>
<option>Val1</option>
<option>Val2</option>
<option>Val3</option>
<option>Val4</option>
</select>
$('#deneme').change(function(){
$.each( $('#deneme').children('option'),function(key,value){
if($(this).is(':selected'))
alert(key)
})
})
u can check from here http://jsfiddle.net/8JZCw/
No need for any iteration here, let jQuery do that for you, just get the selected index and increment...
$('#start_month option:selected').index() + 1
i am using javascript to get the text of selected item from dropdown list.
but i am not getting the text.
i am traversing the dropdown list by name..
my html dropdownlist is as:
<select name="SomeName" onchange="div1();">
<option value="someVal">A</option>
<option value="someOtherVal">B</option>
<option value="someThirdVal">C</option>
</select>
and my javascript is as:
function div1() {
var select = document.getElementsByName("SomeName");
var result = select.options[select.selectedIndex].text;
alert(result);
}
can you please help me out..
Option 1 - If you're just looking for the value of the selected item, pass it.
<select name="SomeName" onchange="div1(this.value);">
<option value="someVal">A</option>
<option value="someOtherVal">B</option>
<option value="someThirdVal">C</option>
</select>
function div1(val)
{
alert(val);
}
Option 2 - You could also use the ID as suggested.
<select id="someID" name="SomeName" onchange="div1();">
<option value="someVal">A</option>
<option value="someOtherVal">B</option>
<option value="someThirdVal">C</option>
</select>
function div1()
{
var ddl = document.getElementById("someID");
var selectedText = ddl.options[ddl.selectedIndex].value;
alert(selectedText);
}
Option 3 - You could also pass the object itself...
<select name="SomeName" onchange="div1(this);">
<option value="someVal">A</option>
<option value="someOtherVal">B</option>
<option value="someThirdVal">C</option>
</select>
function div1(obj)
{
alert(obj.options[obj.selectedIndex].value);
}
getElementsByName returns an array of items, so you'd need:
var select = document.getElementsByName("SomeName");
var text = select[0].options[select[0].selectedIndex].text;
alert(text);
Or something along those lines.
Edit: instead of the "[0]" bit of code, you probably want either (a) to loop all items in the "select" if you expect many selects with that name, or (b) give the select an id and use document.getElementById() which returns just 1 item.
The problem with the original snippet posted is that document.getElementsByName() returns an array and not a single element.
To fix the original snippet, instead of:
document.getElementsByName("SomeName"); // returns an array
try:
document.getElementsByName("SomeName")[0]; // returns first element in array
EDIT: While that will get you up and running, please note the other great alternative answers here that avoid getElementsByName().
