Laravel & Ajax, Jquery - Input Value Of Select Dropdown To Textbox

How can I achieve this output? I want a dynamic dropdown like when I select a value on the dropdown then it the textbox should be filled with its connected value automatically h

Solution 1:

You're targeting the wrong element in the jquery. If you want to change the value of the textbox when the select dropdown is changed then you need to target the select. Change the target element from .aircraft_id to .aircraftsName on this line $(document).on('change', '.aircraftsName', function() {.

Also, you don't need to make a call to the controller. You could put the aircraft_id as the value in the select dropdown. Updating the way the select dropdown is created to something like this might work:

<select name="aircraft_name" class="aircraftsName">
    <option value="0" disabled="true" selected="true"> Select </option>
    @foreach ($aircrafts as $aircraft)
       <option value="{{ $aircraft->aircraft_id }}">{{ $aircraft->aircraft_registration_number }}</option>
    @endforeach
</select>

Then your jquery could be as simple as this:

$(document).ready(function() {
    $(document).on('change', '.aircraftsName', function() {
        var air_id =  $('.aircraftsName').val();     // get id the value from the select
        $('.aircraft_id').val(air_id);   // set the textbox value// if you want the selected text instead of the value// var air_text = $('.aircraftsName option:selected').text(); 
    });
});

If you want to use an ajax call I've updated the code a little:

$(document).ready(function() {
    $(document).on('change', '.aircraftsName', function() {
        var air_id =  $(this).val();

        var a = $(this).parent();

        console.log("Its Change !");

        var op = "";

        $.ajax({
            type: 'get',
            url: '/admin/settings/findAirName',
            data: { 'id': air_id },
            dataType: 'json',      //return data will be jsonsuccess: function(data) {
                // console.log("price");console.log(data.registred_company_name);

                a.find('.aircraft_id').val(data.aircraft_id); 
                // do you want to display id or registration name?
            },
            error:function(){

            }
        });
    });
});

This might get you closer. Since it's a get request you could append the id to the url and not use the data parameter: url: '/admin/settings/findAirName?id=' + air_id;, but don't include the line data: {id: air_id}.

Solution 2:

you can do it this way:

VIEW

<span>Aircraft Name</span>
<select id="aircraft_name" name="aircraft_name" class="aircraftsName">
    <option value="0" disabled="true" selected="true"> Select </option>
    @foreach ($aircrafts as $aircraft)
       <option value="{{ $aircraft->id}}">{{ $aircraft->aircraft_registration_number }}</option>
    @endforeach
</select>

<span>Aircraft ID</span>
<input id="aircraft_id"type="text" class="aircraft_id">

//JS
$(document).ready(function(){
  $("#aircraft_name").change(function(){
    var air_id =  $(this).val();
    $("#aircraft_id").val(air_id );
  });
});

I've added id on the select and input element
