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 = $('#ioConceptName option:selected').text();
E.g. I have an HTML form:
<form role="search" method="get" id="searchform" action="" >
<!-- DIRECT SEARCH INPUT TO SEARCH STRING -->
<input type="text" value="" name="s" id="s" />
<input type="submit" id="searchsubmit" value="Search" />
<!-- DROPDOWN TO SELECT ONE CHOICE -->
<select name='country' id='country' class='postform' >
<option class="level-0" value="2">USA</option>
<option class="level-0" value="3">Canada</option>
<option class="level-0" value="4">Mexico</option>
<option class="level-0" value="5">Cuba</option>
</select>
<!-- CHECKBOXES TO SELECT MULTIPLE CHOICES -->
<div id="color">
<input type="checkbox" name="" value="21" />Beachfront
<input type="checkbox" name="" value="16" />TV
<input type="checkbox" name="" value="20" />Internet
<input type="checkbox" name="" value="17" />Pets Allowed
</div>
</form>
<div id="results"><!-- THE AJAX RESULTS GOES HERE --></div>
And I want to be able to make AJAX request every time the user:
1) write something in the search input box and click search button
OR
2) select one choice from the dropdown menu
OR
3) select one or multiple choices from the checkboxes that are checked
The problem is that I don't know how to structure my JavaScript code correctly and what is the best way to remember and manage choices that the user selected before, to take all things in account. For example, not just the search term when he write something and click search button, but also to take in count the dropdown choice (probably done one step before) and maybe the checked options from checkboxes if he has checked something before. Here is what I have so far:
jQuery(document).ready(function($){
// RESULTS SHOULD APPEAR IN #results DIV AFTER AJAX IS DONE
var $maincontent = $('#results');
// SEARCH INPUT PROCESSING
$('#searchsubmit').click(function(e){
e.preventDefault();
var searchval = $('#s').val();
$.post(
WPaAjax.ajaxurl,
{
action : 'ajax_search_action_do',
searchval : searchval
},
function( response ) {
$maincontent.empty();
$maincontent.append( response );
}
);
});
// COUNTRY DROPDOWN CHOICE PROCESSING
$('#country').on('change', function() {
var countryval = this.value;
$maincontent.animate({ opacity : '0.1' })
$.post(
WPaAjax.ajaxurl,
{
action : 'ajax_search_action_do',
countryval : countryval
},
function( response ) {
$maincontent.empty();
$maincontent.append( response );
$maincontent.animate({ opacity : '1' })
}
);
return false;
});
// CHECKBOXES PROCESSING
$('#color input[type=checkbox]').click(function() {
if (this.checked) {
// code if checked
}
else {
// nothing
}
});
});
As you can see, it's very bad. Because one "function" checks only click, one change and I don't know how to grab values from the checkboxes and make an array and send it via ajax ;(.
Any idea how to structure the JavaScript code so it is not so separated and the checks are somehow in one part (or more logical) instead of three separated parts?
Any ideas are welcome.
Create som logic :
var _do = {
bind: function() {
var self = this;
$('#searchsubmit').on('click', function(e){
e.preventDefault();
self.ajax('searchval', $('#s').val());
});
$('#country').on('change', function() {
self.ajax('countryval', this.value);
});
return self;
},
ajax: function(key, value) {
var data = {action: 'ajax_search_action_do'};
data[key] = value;
$.post(
WPaAjax.ajaxurl, data, function( response ) {
$maincontent.empty().append( response );
}
);
}
}
jQuery(document).ready(function($){
_do.bind();
});
Maybe use jquery.form.js?
http://malsup.com/jquery/form/
It's a great plugin, just structure the form like it was a normal redirection form, add array in name of checkboxes
<input type="checkbox" name="types[]" value="21" />Beachfront
Add target URL to the form, and then...
When u want to submit the form just do
$('searchform').ajaxSubmit({
success: function() {
// callback
}
)
Trigger this on checkboxes change, dropdown change etc. To make the code clean, use one selector
$('#country, #s, #color input').on('change', sendAjaxForm);
How do I can iterate through all checkboxes on the page with JQuery?
I.e. I have those checkboxes above...
<div>
<input checked="checked" type="checkbox" name="option_1" id="checkbox_1" value="1" />35 MM
<input checked="checked" type="checkbox" name="option_2" id="checkbox_2" value="2" /> DIGITAL
<input type="checkbox" name="option_3" id="checkbox_3" value="3" /> 3D DIGITAL
</div>
Have I use
$('input[id^="checkbox_"]').each(function() {
});
Is it correct? Thank you!
$("input[type='checkbox']").each(function(){
var name = $(this).attr('name'); // grab name of original
var value = $(this).attr('value'); // grab value of original
var ischecked = $(this).is(":checked"); //check if checked
});
You can use this to iterate through the checkboxes:
$("input:checkbox").each(function() {
alert($(this).val());
});
jQuery supports a selector :checkbox that is just for selecting checkboxes on the page so if you want all checkboxes on the page that's the simplest way to do it:
$(":checkbox").each(function(index, element) {
// put your code here
});
In the jQuery doc for :checked, they recommend that this selector might perform slightly faster:
$("input[type='checkbox']").each(function(index, element) {
// put your code here
});
$('input[type="checkbox"]').each(function() {
...
});
It seem alright but you can add further type check to ensure not other control type with mataching id comes in selector.
$('input[type=checkbox][id^="checkbox_"]').each(function() {
});
I'm having trouble trying to accomplishing this.. Whatever option I select from a dropdown list named programs_dropdown I want to add to a text field named programs_input and separate the options values by a comma.
e.g. php, jquery, html
Below the dropdown list I have an add div. On click, it should add what I selected from the dropdown to the text field.
$(document).ready(function(){
$('#add').click(function() {
var programs = $("#programs_dropdown").val(); //get value of selected option
$('#programs_input').val(programs.join(',')); //add to text input
});
});
HTML
<select name="programs_dropdown" id="programs_dropdown">
<option value="php">php</option>
<option value="jquery">jquery</option>
<option value="html" selected="selected">HTML</option>
</select>
<div id=add">Add</div>
<input type="text" name="programs_input" id="programs_input" />
I'm getting skill.join is not a function
The select has to multi option if you want to select multiple. Change it to
<select name="programs_dropdown" id="programs_dropdown" multiple>
Then it would start working.
Demo
EDIT:
$(document).ready(function(){
$('#add').click(function() {
var program = $("#programs_dropdown").val(); //get value of selected option
var programs = $('#programs_input').val().split(",");
if (programs[0] == "") {
programs.pop()
}
if ($.inArray(program, programs) == -1) {
programs.push(program);
}
$('#programs_input').val(programs.join(',')); //add to text input
});
});
DEMO
I think this is what you require Demo
I'm somewhat new to jQuery. I'm pretty sure this is possible, but I'm not quote certain how to code this.
What I'm looking to do is to use a dropdown with selections that represent ranges (e.g. if someone were searching for bedrooms, the dropdown selctions would look like "0-2", "3-5", "6+"). Then when someone chooses a selection, two hidden fields would by dynamically filled. One field with the minimum of the range, and the other field with the maximum of the range.
Here is an example of how I'm trying to structure this:
<select id="bedrooms" class="dropdown">
<option>Bedrooms</option>
<option></option>
<option value="1">0-2</option>
<option value="2">3-5</option>
<option value="3">6+</option>
</select>
<input type="hidden" name="bedrooms-from" value=''>
<input type="hidden" name="bedrooms-to" value=''>
I suppose the values of each option could change, I wasn't sure what the best way to approach that would be.
I haven't actually run this, but I think it should work:
$("#bedrooms").change(function ()
{
// Get a local reference to the JQuery-wrapped select and hidden field elements:
var sel = $(this);
var minValInput = $("input[name='bedrooms-from']");
var maxValInput = $("input[name='bedrooms-to']");
// Blank the values of the two hidden fields if appropriate:
if (sel.val() == "") {
minValInput.val("");
maxValInput.val("");
return;
}
// Get the selected option:
var opt = sel.children("[value='" + sel.val() + "']:first");
// Get the text of the selected option and split it on anything other than 0-9:
var values = opt.attr("text").split(/[^0-9]+/);
// Set the values to bedroom-from and bedroom-to:
minValInput.val(values[0]);
maxValInput.val((values[1] != "") ? values[1] : 99999999);
});
$("select").on("change", function() {
$("form").append( /* <input type='hidden'> tag here */ );
});
