title: Jquery .ajax() Returns No Response Body if dataType is JSON
body: <p>I am trying to login to a server through an API, but I'm having an issue where setting the 'dataType' to JSON causes me to receive 'No Response Body'.</p>
  
  <p>When dataType is 'json' I receive this back:</p>
  
  <pre><code>Request URL:    http://104.236.232.23/api/user/login/?Email=haye123%40gmail.com&amp;Password=password&amp;_=1438891065386

  <p>However, if I change the dataType to 'script' I receive this:</p>

  <p>What could be causing the Response body to not show up when json is set as the dataType?</p>
  
  <p>Below is the code in question:</p>
  
  <pre><code>function Login2() {
    if( xhr != null ) {
      xhr.abort();
      xhr = null;
    }
  
    ajax_url = "http://104.236.232.23/api/user/login/";
    ajax_type = "GET";
    ajax_data = {'Email' : "email@gmail.com", 'Password' : "password" };
  
    xhr = $.ajax({
      url: ajax_url,
      type: ajax_type,
      data: ajax_data,
      crossDomain: true,
      dataType: 'json',
      xhrFields: {
        withCredentials: true
      },
      headers: {
        'Accept': '*/*'
      },
      success: function(data, textStatus, XMLHttpRequest){
        alert("boom");
        var cookietoSet=XMLHttpRequest.getResponseHeader('Set-Cookie');
        Set_Cookie(cookietoSet.split('=')[0],cookietoSet.split('=')[1],expires, path, domain, secure) //change as per ur needs
      }, //close success
      error: function( jqXHR, textStatus ){
        alert( "Request failed: " + textStatus );
      }
    });
  } //end function
  </code></pre>
