How to retrieve data using ajax and without going to post page? Laravel 5

I’m new to using ajax. For example after field title is filled, I want to search in database for specific data and return more fields based on that input. So far I can only receive my title data in /ajax/post page by pressing get data/post data or submit button. How do I receive my title input and data from Route::post while/after filling title? If I remove Form::model and Form::close() I do get my dummy data from Route::post without page refresh by clicking Post data button, but without title value.

I’m aware that checking title field involves some jQuery/js, but I have no idea how to actually bring that title field into my route to do some database searching and return some data with it.


            {!! Form::model($project = new AppProject, ['url' => 'ajax/post', 'method' => 'post']) !!}
            <!-- pass through the CSRF (cross-site request forgery) token -->
            <meta name="csrf-token" content="<?php echo csrf_token() ?>" />

            <!-- some test buttons -->
            <button id="get">Get data</button>
            <button id="post">Post data</button>

            <div class="form-group padding-top-10">
              {!! Form::label('title', 'Title') !!}
              {!! Form::text('title', null, ['class' => 'form-control', 'placeholder' => 'Title']) !!}
            {!! Form::submit('Submit Button', ['class' => 'btn btn-primary form-control']) !!}
            {!! Form::close() !!}

Ajax script:
    $.ajaxSetup({ headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') } });
    function onGetClick(event)
        // we're not passing any data with the get route, though you can if you want
        $.get('/ajax/get', onSuccess);
    function onPostClick(event)
        // we're passing data with the post route, as this is more normal
        $.post('/ajax/post', {payload:'hello'}, onSuccess);
    function onSuccess(data, status, xhr)
        console.log(data, status, xhr);
        // JSON is deserialised into an object
    $('button#get').on('click', onGetClick);
    $('button#post').on('click', onPostClick);

And in route:
    Route::get('/ajax/view', ['as' => 'home', 'uses' => '<a href="" class="__cf_email__" data-cfemail="e6a78c879ea589889294898a8a8394a6908f8391">[email protected]</a>']);
    Route::get('/ajax/get', function () {
        $data   = array('value' => 'some get');
        return  Response::json($data);
    Route::post('/ajax/post', function () {
        $data   = array('value' => 'some data', 'input' => Request::input());
        return  Response::json($data);

Method 1

What you need is to implement the jquery keypress function.

so here is you js:

    var title = $(this).val();

    // now do the ajax request and send in the title value
        url: 'url you want to send the request to',
        data: {"title": title}, 
        success: function(response){
           // here you can grab the response which would probably be 
           // the extra fields you want to generate and display it

as far as in Laravel you can pretty much treat it the same as a typical request except you will return json:
Route::get('/url-to-handle-request', function({
    // lets say what you need to populate is 
   //authors from the title and return them

   $title = Route::get('title'); // we are getting the value we passed in the ajax request

    $authors = Author::where('title' ,'=', $title)->get();

    return response()->json([
        'authors' => $authors->toArray();

Now I would probably use a controller and not just do everything within the route but I think you’ll get the basic idea.
