I have a form with this disabled select element (I have disabled it with jquery)
<select class="select form-control" id="ifacility" name="facility">
<option value="" selected="selected">------</option>
<option value="1">Room 1</option>
<option value="2">Room 1</option>
<option value="3">Room 2</option>
<option value="4">Room 3</option>
</select>
I want to use Jquery to find an option with a name eg Room 2 and make it selected.
$(document).on('click', '.select-option', function() {
var room = $(this).attr('value') //This is what gives the 'Room 2'
//I want to select this room from the options and make it selected
});
You don't really need jQuery for this, so here's a plain-old JavaScript solution.
Declare this function:
function setOptionByValue(select, value){
var options = select.options;
for(var i = 0, len = options.length; i < len; i++){
if(options[i].textContent === value){
select.selectedIndex = i;
return true; //Return so it breaks the loop and also lets you know if the function found an option by that value
}
}
return false; //Just to let you know it didn't find any option with that value.
}
Use it like this:
setOptionByValue(document.getElementById('ifacility'), 'Room 2');
Demo
A jQuery solution using filter():
var room2 = $('#ifacility option').filter(function() {
return $(this).text() == 'Room 2';
});
// room2.val() = '3'
$('#ifacility').val(room2.val());
Fiddle
If you want to user jQuery to accomplish task, try this
$('#ifacility').find('option:contains("Room 2")').prop('selected', true);
It finds option by text and sets its selected attribute.

I need a select element's options to change depending on the value of another.
<select id="first">
<option value="1">one</option> // When you click this one, all the values of #second change (arbitrary number of entries)
<option value="2">two</option> // When you click this one, all the values of #second change to something else (not necessarily the same number)
</select>
<select id="second">
<option value="thisChanges">soDoesThis</option>
<option value="thisToo">andThis</option>
</select>
<script>
$("#first").on("change", function() {
<pseudo>
if #first == "1"
#second = {"this", "that", "the other"}
else if #first == "2"
#second = {"more", "even more", "yet another", "still more"}
</pseudo>
}
</script>
This is pretty much what I'm after (took me years to figure out how to completely replace the values of a select box), but the button click event doesn't even work. It was working a minute ago, although the for loop was not.
Obviously for my use case I would check if the select is clicked and retrieve its value with .val(), but I figured this button is easier for debugging.
JSFiddle
HTML:
<select id="sel">
<option value="1">One</option>
<option value="2">Two</option>
</select>
<button>
Click me
</button>
JS:
var list = ['11', 'Eleven', '12', 'Twelve', '13', 'Thirteen'];
$('button').on('click', function () {
alert('click');
var sel = $('#sel');
alert('1');
sel.empty();
alert('2');
for (i = 0, i < list.length; i+2) {
$('#sel').append('<option value="' + list[i] + '">' + list[i+1] + '</option>');
}
alert('3');
});
I think you requirement similiar to the cascading dropdownlist, if i have understood correctly.
Ex jquery code:
$(document).ready(function () {
$("#state").prop("disabled", true);
$("#country").change(function () {
if ($("#country").val() != "Please select") {
var options = {};
options.url = "/home/getstates";
options.type = "POST";
options.data = JSON.stringify({ country: $("#country").val() });
options.dataType = "json";
options.contentType = "application/json";
options.success = function (states) {
$("#state").empty();
for (var i = 0; i < states.length; i++) {
$("#state").append("<option>" + states[i] + "</option>");
}
$("#state").prop("disabled", false);
};
options.error = function () { alert("Error retrieving states!"); };
$.ajax(options);
}
else {
$("#state").empty();
$("#state").prop("disabled", true);
}
});
});
Kindly refer this good article for the complete code:

Hope it will helps

Since you specified jQuery, I'll give you a jQuery answer! Grab the value and the text from the selected option, and append a new one to the select:
$(document).on('change', '#two', function() {
var option_to_add = $(this).find("option:selected").text();
var number_of_options = $('#two option').length
$('#one').append($('<option>', {
value: number_of_options,
text: option_to_add
}));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="one">
<option value="cash">Cash</option>
<option value="money">Money</option>
</select>
<select id="two">
<option value="stack">Stack</option>
<option value="overflow">Overflow</option>
<option value="my">My</option>
<option value="question">Question</option>
<option value="op1">Should be option 1: <a id="option1"></a></option>
</select> Should also be option 1:
<div id="option1"></div>
Based on your comments and changes to your post, if you just want to replace the options in a select element using a dummy array (or array of arrays,) you can do so the following way see code comments for details:
// dummy data array of arrays
var list = [
[11, "Eleven"],
[12, "Twelve"],
[13, "Thirteen"]
];
// click the button, replace the select contents
$('#btn').on('click', function() {
// build an array of option objects from an array of arrays
// see below
var opt_array = build_opt_array(list);
$('#sel').empty();
// add the new options
$(opt_array).each(function(index) {
$('#sel').append(opt_array[index]);
});
});
// helper function
// builds a new array of option html objects from
// an array of arrays
function build_opt_array(items) {
var opt_array = [];
$(items).each(function(index) {
var new_option = $('<option>', {
value: items[index][0],
text: items[index][1]
});
opt_array.push(new_option);
});
return opt_array;
};
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="sel">
<option value="1">One</option>
<option value="2">Two</option>
</select>
<button id="btn">
Click me
</button>
To get the text found in the first Select field, use the .text() function after using find(":selected") on your desired select field.
$("#two").focus(function() {
document.getElementById("option1").innerHTML = $("#one").find(":selected").text();
});
I'm trying to copy or move one select box item to another select box. The problem is that when one or more items are moved from the first box to the second, it should be selected. But it's not working.
My Code
function SelectMoveRows(SS1,SS2)
{
var SelID='';
var SelText='';
var SelText2='';
// Move rows from SS1 to SS2 from bottom to top
for (i=SS1.options.length - 1; i>=0; i--)
{
if (SS1.options[i].selected == true)
{
SelID=SS1.options[i].value;
SelText=SS1.options[i].text;
SelText2=SS1.options[i].attr("selected");
var newRow = new Option(SelText,SelID,SelText2);
SS2.options[SS2.length]=newRow;
SS1.options[i]=null;
}
}
SelectSort(SS2);
}
Then I use
SelText2=SS1.options[i].attr("selected");
But it's not working. If I use:
SelText2=SS1.options[i].select=true;
then option looks like:
<option value="3" selected="">Delivery</option>
But it should be:
<option value="3" selected="selected">Delivery</option>
In the option tag, the attribute selected doesn't need a value:
<option value="3" selected>Delivery</option>
is the same as
<option value="3" selected="selected">Delivery</option>
check it here:
http://jsfiddle.net/n99L2xhv/1/
you should use .prop not .attr
e.g.
SelText2=SS1.options[i].prop("selected", true);
for reference: .prop() vs .attr()
Update I would go about doing this as follows;
<select id="select1">
<option value="1">Option1</option>
<option value="2">Option2</option>
</select>
<select id="select2">
<option value="3">Option3</option>
</select>
$("#select1").change(function(){
$("#select1 option:selected").each(function() {
var option = $(this);
$("#select2").append(option);
$("#select1").remove(option);
});
});
This will shift the selected option from Select 1 to Select 2 when it is chosen.
As pointed out by David Thomas in the comments, .attr() is not a valid method on a select element; It is a method on a jQuery object, which you don't have.
You could just pass true as the parameter to the Option constructor, and the third parameter is really the defaultSelected property, while the fourth paramter is the selected property.
for (var i = SS1.options.length - 1; i >= 0; i--) {
var option = SS1.options[i];
if (option.selected) {
SS2.add(new Option(option.text, option.value, false, true));
SS1.remove(i);
}
}
You could use option.selected instead of true, but because of the if-statement, you know option.selected will always be true.

I'm not sure why this isn't working. Anyone care to take a stab?
I have a form with the below. When the user selects the "disabled" option in #frmcomments, I'd like #frmstatus to change to the option value of private.
<label for="type">Comments:</label>
<select class="sort-select" id="frmcomments" name="frmcomments">
<option value="enabled">Allow Comments</option>
<option value="disabled">No Comments</option>
</select>
<label for="type">Status:</label>
<select class="sort-select" id="frmstatus" name="frmstatus">
<option value="public">Anyone can see</option>
<option value="private">Only I can see</option>
</select>
I'm using the following jquery, but it's failing?
$('#frmcomments').change(function() {
var thistype = $(this).find(":selected").val();
if(thistype=="disabled") {
$("#frmstatus").val("private");
}
return false;
});
Check your thistype value. You should be able to call val() on the select and you shouldn't have to call .find(":selected") to get the selected list item.
$('#frmcomments').change(function() {
var thistype = $(this).val();
if(thistype=="disabled") {
$("#frmstatus").val("private").change();
}
return false;
});
var thistype = $(this).find(":selected").val();
try this
var thistype = $(this).val();
Is there a way to set the value of a dropdown list in jQuery (or Javascript) based on the node value?
<select name="ddlProperty">
<option value="1" selected="selected"></option>
<option value="2">Animal Kingdom</option>
<option value="3">Epcot</option>
<option value="4">Hollywood Studios</option>
<option value="5">Magic Kingdom</option>
<option value="6">Downtown Disney</option>
</select>
I'd need to set the option of Magic Kingdom, so something like:
$("#ddlLocation").val("Magic Kingdom")
So that Magic Kingdom would become the selected item, that doesn't work as expected. Any ideas?
If you can use the value (not text!), do that using .val():
$("#ddlProperty").val("5");
If you don't have that, use .filter(), .text() and .attr() to find and set the selected <option>, like this:
$("#ddlProperty option").filter(function() {
return $(this).text() === "Magic Kingdom"
}).attr('selected', true);
Something like:
var box = document.getElementById('box'),
options = box.options;
for(var i = 0; i < options.length; ++i){
if(options[i].text == val){
options[i].selected = true;
}
}
$("#ddlProperty > option").each(function(i, elem) {
if($(elem).text() == "Magic Kingdom") {
$('#ddlProperty').val(elem.value);
return false;
}
});
And next time please make a proper example where the element has an id and that ID matches the ID in your code. I've spent about 5 minutes checking for an error until I've noticed the ID being different...
http://jsbin.com/ikibi3/2
myselect="Magic Kingdom";
$("select[name='ddlProperty'] option").each(function() {
if($(this).text() == myselect) {
$(this).attr('selected', true);
} else {
$(this).attr('selected', false);
}
});
I have the following HTML <select> element:
<select id="leaveCode" name="leaveCode">
<option value="10">Annual Leave</option>
<option value="11">Medical Leave</option>
<option value="14">Long Service</option>
<option value="17">Leave Without Pay</option>
</select>
Using a JavaScript function with the leaveCode number as a parameter, how do I select the appropriate option in the list?
You can use this function:
function selectElement(id, valueToSelect) {
let element = document.getElementById(id);
element.value = valueToSelect;
}
selectElement('leaveCode', '11');
<select id="leaveCode" name="leaveCode">
<option value="10">Annual Leave</option>
<option value="11">Medical Leave</option>
<option value="14">Long Service</option>
<option value="17">Leave Without Pay</option>
</select>
Optionally if you want to trigger onchange event also, you can use :
element.dispatchEvent(new Event('change'))
If you are using jQuery you can also do this:
$('#leaveCode').val('14');
This will select the <option> with the value of 14.
With plain Javascript, this can also be achieved with two Document methods:
With document.querySelector, you can select an element based on a CSS selector:
document.querySelector('#leaveCode').value = '14'
Using the more established approach with document.getElementById(), that will, as the name of the function implies, let you select an element based on its id:
document.getElementById('leaveCode').value = '14'
You can run the below code snipped to see these methods and the jQuery function in action:
const jQueryFunction = () => {
$('#leaveCode').val('14');
}
const querySelectorFunction = () => {
document.querySelector('#leaveCode').value = '14'
}
const getElementByIdFunction = () => {
document.getElementById('leaveCode').value='14'
}
input {
display:block;
margin: 10px;
padding: 10px
}
<select id="leaveCode" name="leaveCode">
<option value="10">Annual Leave</option>
<option value="11">Medical Leave</option>
<option value="14">Long Service</option>
<option value="17">Leave Without Pay</option>
</select>
<input type="button" value="$('#leaveCode').val('14');" onclick="jQueryFunction()" />
<input type="button" value="document.querySelector('#leaveCode').value = '14'" onclick="querySelectorFunction()" />
<input type="button" value="document.getElementById('leaveCode').value = '14'" onclick="getElementByIdFunction()" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
function setSelectValue (id, val) {
document.getElementById(id).value = val;
}
setSelectValue('leaveCode', 14);
Not answering the question, but you can also select by index, where i is the index of the item you wish to select:
var formObj = document.getElementById('myForm');
formObj.leaveCode[i].selected = true;
You can also loop through the items to select by display value with a loop:
for (var i = 0, len < formObj.leaveCode.length; i < len; i++)
if (formObj.leaveCode[i].value == 'xxx') formObj.leaveCode[i].selected = true;
I compared the different methods:
Comparison of the different ways on how to set a value of a select with JS or jQuery
code:
$(function() {
var oldT = new Date().getTime();
var element = document.getElementById('myId');
element.value = 4;
console.error(new Date().getTime() - oldT);
oldT = new Date().getTime();
$("#myId option").filter(function() {
return $(this).attr('value') == 4;
}).attr('selected', true);
console.error(new Date().getTime() - oldT);
oldT = new Date().getTime();
$("#myId").val("4");
console.error(new Date().getTime() - oldT);
});
Output on a select with ~4000 elements:
1 ms
58 ms
612 ms
With Firefox 10. Note: The only reason I did this test, was because jQuery performed super poorly on our list with ~2000 entries (they had longer texts between the options).
We had roughly 2 s delay after a val()
Note as well: I am setting value depending on the real value, not the text value.
document.getElementById('leaveCode').value = '10';
That should set the selection to "Annual Leave"
I tried the above JavaScript/jQuery-based solutions, such as:
$("#leaveCode").val("14");
and
var leaveCode = document.querySelector('#leaveCode');
leaveCode[i].selected = true;
in an AngularJS app, where there was a required <select> element.
None of them works, because the AngularJS form validation is not fired. Although the right option was selected (and is displayed in the form), the input remained invalid (ng-pristine and ng-invalid classes still present).
To force the AngularJS validation, call jQuery change() after selecting an option:
$("#leaveCode").val("14").change();
and
var leaveCode = document.querySelector('#leaveCode');
leaveCode[i].selected = true;
$(leaveCode).change();
Short
This is size improvement of William answer
leaveCode.value = '14';
leaveCode.value = '14';
<select id="leaveCode" name="leaveCode">
<option value="10">Annual Leave</option>
<option value="11">Medical Leave</option>
<option value="14">Long Service</option>
<option value="17">Leave Without Pay</option>
</select>
The easiest way if you need to:
1) Click a button which defines select option
2) Go to another page, where select option is
3) Have that option value selected on another page
1) your button links (say, on home page)
<a onclick="location.href='contact.php?option=1';" style="cursor:pointer;">Sales</a>
<a onclick="location.href='contact.php?option=2';" style="cursor:pointer;">IT</a>
(where contact.php is your page with select options. Note the page url has ?option=1 or 2)
2) put this code on your second page (my case contact.php)
<?
if (isset($_GET['option']) && $_GET['option'] != "") {
$pg = $_GET['option'];
} ?>
3) make the option value selected, depending on the button clicked
<select>
<option value="Sales" <? if ($pg == '1') { echo "selected"; } ?> >Sales</option>
<option value="IT" <? if ($pg == '2') { echo "selected"; } ?> >IT</option>
</select>
.. and so on.
So this is an easy way of passing the value to another page (with select option list) through GET in url. No forms, no IDs.. just 3 steps and it works perfect.
function foo(value)
{
var e = document.getElementById('leaveCode');
if(e) e.value = value;
}
Suppose your form is named form1:
function selectValue(val)
{
var lc = document.form1.leaveCode;
for (i=0; i<lc.length; i++)
{
if (lc.options[i].value == val)
{
lc.selectedIndex = i;
return;
}
}
}
Should be something along these lines:
function setValue(inVal){
var dl = document.getElementById('leaveCode');
var el =0;
for (var i=0; i<dl.options.length; i++){
if (dl.options[i].value == inVal){
el=i;
break;
}
}
dl.selectedIndex = el;
}
Why not add a variable for the element's Id and make it a reusable function?
function SelectElement(selectElementId, valueToSelect)
{
var element = document.getElementById(selectElementId);
element.value = valueToSelect;
}
Most of the code mentioned here didn't worked for me!
At last, this worked
window.addEventListener is important, otherwise, your JS code will run before values are fetched in the Options
window.addEventListener("load", function () {
// Selecting Element with ID - leaveCode //
var formObj = document.getElementById('leaveCode');
// Setting option as selected
let len;
for (let i = 0, len = formObj.length; i < len; i++){
if (formObj[i].value == '<value to show in Select>')
formObj.options[i].selected = true;
}
});
Hope, this helps!
You most likely want this:
$("._statusDDL").val('2');
OR
$('select').prop('selectedIndex', 3);
If using PHP you could try something like this:
$value = '11';
$first = '';
$second = '';
$third = '';
$fourth = '';
switch($value) {
case '10' :
$first = 'selected';
break;
case '11' :
$second = 'selected';
break;
case '14' :
$third = 'selected';
break;
case '17' :
$fourth = 'selected';
break;
}
echo'
<select id="leaveCode" name="leaveCode">
<option value="10" '. $first .'>Annual Leave</option>
<option value="11" '. $second .'>Medical Leave</option>
<option value="14" '. $third .'>Long Service</option>
<option value="17" '. $fourth .'>Leave Without Pay</option>
</select>';
I'm afraid I'm unable to test this at the moment, but in the past, I believe I had to give each option tag an ID, and then I did something like:
document.getElementById("optionID").select();
If that doesn't work, maybe it'll get you closer to a solution :P
