How to get all options of a select using jQuery?
JavascriptJqueryJquery SelectorsJavascript Problem Overview
How can I get all the options of a select through jQuery by passing on its ID?
I am only looking to get their values, not the text.
Javascript Solutions
Solution 1 - Javascript
Use:
$("#id option").each(function()
{
// Add $(this).val() to your list
});
Solution 2 - Javascript
Without jQuery
I do know that the HTMLSelectElement
element contains an options
property, which is a HTMLOptionsCollection
.
const myOpts = document.getElementById('yourselect').options;
console.log(myOpts[0].value) //=> Value of the first option
A 12 year old answer. Let's modernize it a bit (using .querySelectorAll
, spreading the resulting HTMLOptionsCollection
to Array
and map the values).
// helper to retrieve an array of elements using a css selector
const nodes = selector => [...document.querySelectorAll(selector)];
const results = {
pojs: nodes(`#demo option`).map(o => o.value),
jq: $(`#demo option`).toArray().map( o => o.value ),
}
console.log( `pojs: [${results.pojs.slice(0, 5)}]` );
console.log( `jq: [${results.jq.slice(0, 5)}]` );

$.map
is probably the most efficient way to do this.
var options = $('#selectBox option');
var values = $.map(options ,function(option) {
return option.value;
});
You can add change options to $('#selectBox option:selected')
if you only want the ones that are selected.
The first line selects all of the checkboxes and puts their jQuery element into a variable. We then use the .map
function of jQuery to apply a function to each of the elements of that variable; all we are doing is returning the value of each element as that is all we care about. Because we are returning them inside of the map function it actually builds an array of the values just as requested.
Solution 4 - Javascript
Some answers uses each
, but map
is a better alternative here IMHO:
$("select#example option").map(function() {return $(this).val();}).get();
There are (at least) two map
functions in jQuery. Thomas Petersen's answer uses "Utilities/jQuery.map"; this answer uses "Traversing/map" (and therefore a little cleaner code).
It depends on what you are going to do with the values. If you, let's say, want to return the values from a function, map
is probably the better alternative. But if you are going to use the values directly you probably want each
.
Solution 5 - Javascript
$('select#id').find('option').each(function() {
alert($(this).val());
});
Solution 6 - Javascript
This will put the option values of #myselectbox
into a nice clean array for you:
// First, get the elements into a list
var options = $('#myselectbox option');
// Next, translate that into an array of just the values
var values = $.map(options, e => $(e).val())
Solution 7 - Javascript
$("#id option").each(function()
{
$(this).prop('selected', true);
});
Although, the CORRECT way is to set the DOM property of the element, like so:
$("#id option").each(function(){
$(this).attr('selected', true);
});
Solution 8 - Javascript
You can take all your "selected values" by the name of the checkboxes and present them in a sting separated by ",".
A nice way to do this is to use jQuery's $.map():
var selected_val = $.map($("input[name='d_name']:checked"), function(a)
{
return a.value;
}).join(',');
alert(selected_val);
Solution 9 - Javascript
The most efficient way to do this is to use $.map()
Example:
var values = $.map($('#selectBox option'), function(ele) {
return ele.value;
});
Solution 10 - Javascript
You can use following code for that:
var assignedRoleId = new Array();
$('#RolesListAssigned option').each(function(){
assignedRoleId.push(this.value);
});
Solution 11 - Javascript
For multiselect option:
$('#test').val()
returns list of selected values.
$('#test option').length
returns total number of options (both selected and not selected)
Solution 12 - Javascript
Here is a simple example in jquery to get all the values, texts, or value of the selected item, or text of the selected item
$('#nCS1 > option').each((index, obj) => {
console.log($(obj).val());
})
printOptionValues = () => {
$('#nCS1 > option').each((index, obj) => {
console.log($(obj).val());
})
}
printOptionTexts = () => {
$('#nCS1 > option').each((index, obj) => {
console.log($(obj).text());
})
}
printSelectedItemText = () => {
console.log($('#nCS1 option:selected').text());
}
printSelectedItemValue = () => {
console.log($('#nCS1 option:selected').val());
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select size="1" id="nCS1" name="nCS1" class="form-control" >
<option value="22">Australia</option>
<option value="23">Brunei</option>
<option value="33">Cambodia</option>
<option value="32">Canada</option>
<option value="27">Dubai</option>
<option value="28">Indonesia</option>
<option value="25">Malaysia</option>
</select>
<br/>
<input type='button' onclick='printOptionValues()' value='print option values' />
<br/>
<input type='button' onclick='printOptionTexts()' value='print option texts' />
<br/>
<input type='button' onclick='printSelectedItemText()' value='print selected option text'/>
<br/>
<input type='button' onclick='printSelectedItemValue()' value='print selected option value' />
Solution 13 - Javascript
var arr = [], option='';
$('select#idunit').find('option').each(function(index) {
arr.push ([$(this).val(),$(this).text()]);
//option = '<option '+ ((result[0].idunit==arr[index][0])?'selected':'') +' value="'+arr[index][0]+'">'+arr[index][1]+'</option>';
});
console.log(arr);
//$('select#idunit').empty();
//$('select#idunit').html(option);
Solution 14 - Javascript
This is a simple Script with jQuery:
var items = $("#IDSELECT > option").map(function() {
var opt = {};
opt[$(this).val()] = $(this).text();
return opt;
}).get();
var selectvalues = [];
for(var i = 0; i < items.length; i++) {
for(key in items[i]) {
var id = key;
var text = items[i][key];
item = {}
item ["id"] = id;
item ["text"] = text;
selectvalues.push(item);
}
}
console.log(selectvalues);
copy(selectvalues);
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="mercedes">Mercedes</option>
<option value="audi">Audi</option>
</select>
Solution 15 - Javascript
$("input[type=checkbox][checked]").serializeArray();
Or:
$(".some_class[type=checkbox][checked]").serializeArray();
To see the results:
alert($("input[type=checkbox][checked]").serializeArray().toSource());
Solution 16 - Javascript
If you're looking for all options with some selected text then the below code will work.
$('#test').find("select option:contains('B')").filter(":selected");
Solution 17 - Javascript
The short way
$(() => {
$('#myselect option').each((index, data) => {
console.log(data.attributes.value.value)
})})
or
export function GetSelectValues(id) {
const mData = document.getElementById(id);
let arry = [];
for (let index = 0; index < mData.children.length; index++) {
arry.push(mData.children[index].value);
}
return arry;}
Solution 18 - Javascript
I found it short and simple, and can be tested in Dev Tool console itself.
$('#id option').each( (index,element)=>console.log(
index : ${index}, value : ${element.value}, text : ${element.text} ) )
Solution 19 - Javascript
Another way would be to use toArray()
in order to use fat arrow function with map e.g:
const options = $('#myselect option').toArray().map(it => $(it).val())
Solution 20 - Javascript
This is a very simple way to generate a list of comma separated values.
var values = "";
$('#sel-box option').each(function () {
values = values + $(this).val() + ";";
});
