Realization of random generator of famous sayings based on JQuery and AJAX

This is a small application that I made when I first came into contact with AJAX. The main functions are as follows:

1. Click the button to randomly generate a famous saying and its author's name. If there is no author's name, "Unknown" will be displayed.
2. Click the button to share famous sayings on Twitter or Weibo.

HTML:

<div class="container-fluid text-center">

JQuery:

$(document).ready(function() { 
 var quote, author; 
 
 function getNewQuote() { 
  $.ajax({ 
   type: "get", 
   url: "http://api.forismatic.com/api/1.0/", 
   jsonp: 'jsonp', 
   dataType: 'jsonp', 
   data: { 
    method: 'getQuote', 
    lang: 'en', 
    format: 'jsonp' 
   }, 
   success: function(response) { 
    quote = response.quoteText; 
    author = response.quoteAuthor; 
    $('.quote').text('\"' + quote + '\"'); 
    if (author) { 
     $('.author').text('by ' + author); 
    } else { 
     $('.author').text('by Unknown'); 
    } 
   } 
  }); 
 } 
 
 getNewQuote(); 
 
 $('#change').on('click', 
 function(event) { 
  event.preventDefault(); 
  getNewQuote(); 
 }); 
 
 $('#tweet').on('click', 
 function(event) { 
  event.preventDefault(); 
  window.open('http://twitter.com/intent/tweet?text=' + encodeURIComponent(quote + ' by ' + author)); 
 }); 
 
 $('#weibo').on('click', 
 function(event) { 
  event.preventDefault(); 
  window.open('http://v.t.sina.com.cn/share/share.php?title=' + encodeURIComponent(quote + ' by ' + author)); 
 }) 
}); 

* forismatic's API can get famous sayings, but only English and Russian versions... However, there are many similar API in Chinese, and the implementation principles are similar.
