JSON Response parse error from controller

Question

Magento 1 - I keep getting a parse error. I can't figure out where my syntax is wrong.

$this->getResponse()->setHeader('Content-type', 'application/json');
$this->getResponse()->setBody(json_encode({"user": true}));

This is my ajax request:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
 <script type="text/javascript">
 $(document).ready(function(){
 $(".emailfocusout").focusout(function(){
 var email = $('.emailfocusout').val();
 console.log('EMAIL: ', email);
 $.ajax({
 url: '/checkout/Email/Email/email/' + email,
 type: 'POST',
 contentType: 'application/json',
 success: function(data) {
 console.log('SUCCESS: ', data);
 },
 error: function(data) {
 console.log('ERROR: ', data);
 },
 });
 });
 });
 </script>

Answer 1

It throws an error because your syntax seems wrong, tries with below syntax

$result = ['user'=>true];
$this->getResponse()->setBody(json_encode($result));

Also, I would suggest you to use core Magento function rather then core PHP function,

$this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));

• Che Figueroa: When I check the Network tab, it still says: SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data I updated the original question with the ajax request. I trigger the error function with the response.
