Select2: How to select the "value" of an option?

Select2: How to select the "value" of an option? - javascript

I have a dropdown of countries:
<select size="1" class="product-load-port" name="product-load-port">
<option value=""></option>
<option value="AF">Afghanistan</option>
<option value="AX">Aland Islands</option>
<option value="AL">Albania</option>
<option value="DZ">Algeria</option>
</select>
How to select the value of the chosen country, ex. if Albania was chosen, value should be "AL"?
I'm trying to do that with
$('select.product-load-port').select2('data')[0].text;
but it gives me "Albania" as a value.

You can do that by simply accessing the .val() of the underlying native <select> element:
$('select.product-load-port').val()
You can also proxy it through .select2().val(), but that's not really necessary anyway:
$('select.product-load-port').select2().val()
$('select.product-load-port').select2();
$('#getSelectedValue').on('click', function() {
console.log($('select.product-load-port').val());
});

<option value="AF">Afghanistan</option>
<option value="AX">Aland Islands</option>
<option value="AL">Albania</option>
<option value="DZ">Algeria</option>
</select>
<button type="button" id="getSelectedValue">Log selected value to console</button>

How to remove choosen item once it is selected and get it back once unselected

Hi i problem in achieving choosen select/unselect, i'm using https://harvesthq.github.io/chosen/
Question: i want to remove item from drop-down once selected and get it back once unselected
Here is my image showing problem:
below is my whole choosen code:
$('.chosen-select').chosen({}).change( function(obj, result) {
//console.debug("changed: %o", arguments);
console.log("selected: " + result.selected);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/chosen/1.4.2/chosen.min.css">

Other stuff I tried did not work, but the CSS change works fine:
$('.chosen-select').chosen({}).change(function(obj, result) {
console.log("selected: " + result.selected);
/* None of this works. The CSS does work
const vals = $(".chosen-select").val();
$('.chosen-select').find("option[value='"+result.selected+"']").remove()
console.log(vals)
$(".chosen-select").val(vals);
// $('.chosen-select').trigger("chosen:updated");
*/
});
li.result-selected {
display: none !important;

Ignore 1st option from multiple select box-jquery

I have multiple select box with same options which are mutually exclusive .For example if select box A and select box B has option1 ,option2 and option 3 , Then if I select option1 for select box A, then it should not be available on select box B
My demonstration
<select name="select" class="alert_type">
<option selected disabled>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
<select name="select" class="alert_type">
<option selected disabled>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
<select name="select" class="alert_type">
<option selected disabled>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
$('.alert_type').change(function() {
var selected_value=$(this).val();
$(".alert_type option[value='" + selected_value + "']").not(this.selectedOptions[0]).hide();
});
But I want to make 1st option as exception i.e <option value="">Select below</option> as I need flexibility to revert all the option
You can see on fiddle below , if I select option1 from select box 1 ,"select below" from option 3 is also removed which I want to put in exception
Fiddle
https://jsfiddle.net/timus2001/rbuyk7na/3/
When I try with
$(".alert_type option").show();
to show all at first it is not mutually exclusive any more (see the picture)

Ok. let me see if I get you this time:
$('.alert_type').change(function() {
var selected_values = [],
iteration;
$(".alert_type option").show();
$(".alert_type").each(function(){
iteration = $(this).find('option:selected').val();
if ( iteration !== "" ) {
selected_values.push( iteration );
}
})
for ( var i = 0; i < selected_values.length; i++ ) {
$(".alert_type option[value='"+ selected_values[i] +"']").hide();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select name="select" class="alert_type">
<option selected>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
<select name="select" class="alert_type">
<option selected>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
<select name="select" class="alert_type">
<option selected>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>

This is what you need:
$('select.alert_type').on('change keyup',function() {
var val = $(this).val();
$('select.alert_type option').prop('disabled',false);
$(this).siblings().find('option[value='+val+']').prop('disabled',true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="select" class="alert_type">
<option selected disabled>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
<select name="select" class="alert_type">
<option selected disabled>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
<select name="select" class="alert_type">
<option selected disabled>Select below</option>
<option value="1">option1</option>
<option value="2">option2</option>
<option value="3">option3</option>
<option value="4">option4</option>
</select>
Good luck :D

drop down + user input (text)

Hi guys I've looked around and I haven't really gotten a really good answer on this.
So I have a drop down list that allows my users to pick which city they live in and stuff. However I want it so that that drop down has the ability to allow users to first type in their value first or select a value from the drop down.
Here is what I have so far:
<div class="atl_form_row">
<div class="atl_left"><span class="mandatory">*</span>
<label class="control-label atlFormLabel" for="Service City">Service City/County:</label>
</div>
<div class="atl_right">
<select id="ServiceCity" name="ServiceCity">
<option value "" disabled selected>Select City/County</option>
<option value="Alpharetta">Alpharetta</option>
<option value="Atlanta">Atlanta</option>
<option value="Brookhaven">Brookhaven</option>
<option value="Chamblee">Chamblee</option>
<option value="Chattahoochee Hills">Chattahoochee Hills</option>
<option value="College Park">College Park</option>
<option value="Decatur">Decatur</option>
<option value="Douglasville">Douglasville</option>
<option value="Duluth">Duluth</option>
<option value="Dunwoody">Dunwoody</option>
<option value="East Point">East Point</option>
<option value="Fairburn">Fairburn</option>
<option value="Fulton County">Fulton County</option>
<option value="Hapeville">Hapeville</option>
<option value="Johns Creek">Johns Creek</option>
<option value="Marietta">Marietta</option>
<option value="Milton">Milton</option>
<option value="Mountain Park">Mountain Park</option>
<option value="Newnan">Newnan</option>
<option value="Palmetto">Palmetto</option>
<option value="Riverdale">Riverdale</option>
<option value="Roswell">Roswell</option>
<option value="Sandy Springs">Sandy Springs</option>
<option value="Smyrna">Smyrna</option>
<option value="Union City">Union City</option>
</select>
</div>
</div>';

The new HTML5 <datalist> element is what you are looking for:
<input list="ServiceCity">
<datalist id="ServiceCity" name="ServiceCity">
<option value "" disabled selected>Select City/County</option>
<option value="Alpharetta">Alpharetta</option>
<option value="Atlanta">Atlanta</option>
<option value="Brookhaven">Brookhaven</option>
<option value="Chamblee">Chamblee</option>
<option value="Chattahoochee Hills">Chattahoochee Hills</option>
<option value="College Park">College Park</option>
<option value="Decatur">Decatur</option>
<option value="Douglasville">Douglasville</option>
<option value="Duluth">Duluth</option>
<option value="Dunwoody">Dunwoody</option>
<option value="East Point">East Point</option>
<option value="Fairburn">Fairburn</option>
<option value="Fulton County">Fulton County</option>
<option value="Hapeville">Hapeville</option>
<option value="Johns Creek">Johns Creek</option>
<option value="Marietta">Marietta</option>
<option value="Milton">Milton</option>
<option value="Mountain Park">Mountain Park</option>
<option value="Newnan">Newnan</option>
<option value="Palmetto">Palmetto</option>
<option value="Riverdale">Riverdale</option>
<option value="Roswell">Roswell</option>
<option value="Sandy Springs">Sandy Springs</option>
<option value="Smyrna">Smyrna</option>
<option value="Union City">Union City</option>
</datalist>
As the user types in the <input>, the options from the datalist drop down. Or, a double click makes the whole list drop, like a select.
