title: How To Replace jQuery 1.9.1's $.parseJSON function with the implementation from jQuery 1.8.3
body: <p>jQuery has altered it's implementation of $.parseJSON as of version 1.9.0 and we really depended on the way earlier versions of jQuery parsed null and empty strings, e.g. jQuery used to not throw an exception and would return a null value for null and empty string.</p>
  
  <p>We would like to utilize the newest version of jQuery which at the time of writing is 1.9.1, but replace the implementation of $.parseJSON.</p>
  
  <p>Documentation stating the change from jQuery: <a href="http://api.jquery.com/jQuery.parseJSON/" rel="nofollow">http://api.jquery.com/jQuery.parseJSON/</a></p>
  
  <p>Is there some JavaScript we could use to tell jQuery to replace it's "natural" version of the $.parseJSON function with another implementation / function with the same name...the version from jQuery 1.8.3?</p>
  
  <p><a href="http://code.jquery.com/jquery-1.8.3.js" rel="nofollow">http://code.jquery.com/jquery-1.8.3.js</a> has the function's implementation that we need.</p>
