Javascript Question

Problems getting success or done response in $.ajax when using vue.js in Laravel

I have this simple form where the user should only type text inside a textarea. When the user clicks on the submit button, inside the javascript, I make a call with vue and ajax to insert that text into the database.

My problem is that, right after the user clicks on submit, I want the textarea to be cleared, but after the text has been saved into the database, the text is still there. It persists. Since I am using vue.js and ajax, there is this .done (success) callback function I am waiting in order to proceed to clear the form.

Or is there any other idea to clear the textarea, if the text was saved into the database?

Here is my blade code of the form:

<div class="row" id="timeline">
<div class="col-md-4">
<form action="#" v-on:submit="postStatus">{{-- Name of the method in Vue.js --}}
<div class="form-group">
<textarea class="form-control" rows="5" maxlength="140" autofocus placeholder="What are you upto?" required v-model="post" id="textareapost"></textarea>
<input type="submit" value="Post" class="form-control btn btn-info">

{{ csrf_field() }}

<div class="col-md-8">

This is my controller:


namespace App\Http\Controllers;

use App\Post;
use Illuminate\Http\Request;

use App\Http\Requests;

class PostController extends Controller
public function create(Request $request, Post $post)
//Remember, all we really need is the body. Because if create this post through
//the User model, it'll automatically assign us a user_id

'body' => 'required|max:140',
//die('Posted in the controller!: '.$request->body); //$request->get('body');

//creating the post from the user, from the post that belongs to the user:
$createdPost = $request->user()->posts()->create([
'body' => $request->body,

//Now respond with the post that has been created:
return response()->json($post->with('user')->find($createdPost->id));

And the javascript code so far:

var csrf_token = $('meta[name="csrf-token"]').attr('content');
/*Event handling within vue*/
//when we actually submit the form, we want to catch the action
new Vue({
el : '#timeline',
data : {
post : '',
token : csrf_token,
methods : {
postStatus : function (e) {
console.log('Posted: ' '. Token: '+this.token);
var request = $.ajax({
url : '/posts',
method : "POST",
dataType : 'json',
data : {
'body' :,
'_token': this.token,
}).done(function (msg) {
console.log('Data saved: '+msg); = '';/*Attempting to clear the form*/

request.done(function( msg ) {
console.log('Data saved: '+msg+'. Outside ...');
//$( "#log" ).html( msg );
}); jqXHR, textStatus ) {
console.log( "Request failed: " + textStatus );

After the the text has been saved, I never get the console.log text of the .done part, but I get the .fail message which says:

Request failed: parsererror

And the response from the controller is right the following:

<?php{"id":29,"user_id":1,"body":"Sunday evening post","created_at":"2016-10-09 23:03:11","updated_at":"2016-10-09 23:03:11","user":{"id":1,"firstname":null,"lastname":null,"username":"pathros","email":"","created_at":"2016-10-08 05:33:06","updated_at":"2016-10-08 18:57:19"}}

I noticed that the response adds
. Is it maybe the Chrome's inspect elements tool?
What am I missing?
(Note: I am using jQuery 3.1.1 and Laravel 5.3)

Your issue has to do with the dataType option on the AJAX. You currently have dataType: 'json', which means the request is successful when the server returns a JSON.

If you are returning something like return 'ok'; that AJAX will fail.

Make sure you're returning something like:

return Response::json(['ok' => 'true']);
