Uncaught TypeError: jQuery(...).select2 is not a function Laravel 5.3

Question

I am using Select2 and seeing the error below. This is my file:

@extends('layouts.app')
<link rel="stylesheet" type="text/css" href="{{URL::asset('css/select2.min.css')}}">

    @section('content')
    <div class="container">
        <div class="row">
            <div class="col-md-8 col-md-offset-2">
                <div class="panel panel-default">
                    <div class="panel-heading">Dashboard</div>

                    <div class="panel-body">
                         <select name="primaryLanguage" id="primaryLanguage">
                          <option value="AL">Alabama</option>
                          <option value="WY">Wyoming</option>
                        </select>
                    </div>
                </div>
            </div>
        </div>
    </div>
    @endsection
    <script type="text/javascript" src="{{URL::asset('js/jquery-1.10.2.js')}}"></script>
    <script type="text/javascript" src="{{URL::asset('js/select2.full.min.js')}}"></script>
    <script type="text/javascript">
        jQuery(document).ready(function(){
            jQuery("primaryLanguage").select2();
        });
    </script>

Answer 1

i just faced your own problem, i solved it like this: put these

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="/js/select2.min.js"></script>

in your main layout file (in my case app.blade.php) then under those scripts put @yield('scripts') Then in your blade file where you want to call the plugin, after the

@section('content') 
...
@endsection
@section('scripts')
 <!-- Here you call the select2 js plugin -->
@endsection

PS : you must put the css file & js file under public folder (public/css & public/js) And here i'm using Laravel Collective for the forms I hope i helped

Answer 2

just remove this code from you main layout

<script src="{{ asset('js/app.js') }}" defer></script>
