A lightweight example to get Laravel 5 users up to speed with jQuery AJAX

laravel-ajax.php

/**
 * Laravel / jQuery AJAX code example
 * See conversation here: http://laravel.io/forum/04-29-2015-people-asking-about-jquery-ajax
 *
 * Drop this code into your App/Http/routes.php file, and go to /ajax/view in your browser
 * Be sure to bring up the JavaScript console by pressing F12.

// This is your View AJAX route - load this in your browser
Route::get('/ajax/view', function () {

	// really all this should be set up as a view, but I'm showing it here as
	// inline html just to be easy to drop into your routes file and test
	?>

		<!-- jquery library -->
		<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>

		<!-- 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>

		<!-- your custom code -->
		<script>

			// set up jQuery with the CSRF token, or else post routes will fail
			$.ajaxSetup({ headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') } });

			// handlers
			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)
			{
				// with our success handler, we're just logging the data...
				console.log(data, status, xhr);

				// but you can do something with it if you like - the JSON is deserialised into an object
				console.log(String(data.value).toUpperCase())
			}

			// listeners
			$('button#get').on('click', onGetClick);
			$('button#post').on('click', onPostClick);

		</script>

	<?php
});

// this is your GET AJAX route
Route::get('/ajax/get', function () {

	// pass back some data
	$data   = array('value' => 'some data');

	// return a JSON response
	return  Response::json($data);

});

// this is your POST AJAX route
Route::post('/ajax/post', function () {

	// pass back some data, along with the original data, just to prove it was received
	$data   = array('value' => 'some data', 'input' => Request::input());

	// return a JSON response
	return  Response::json($data);
});

This code really helped me to figure this out. Thanks for your help!
