Why is jQuery.parseJSON not a function?

Question

I use the following jQuery statements and I am getting the error,

jQuery.parseJSON is not a function

My function is,

function Iteratejsondata() {var HfJsonValue = 
      { "Table": [{ "Emp_Id": "3",

    //var jsonObj = eval('(' + HfJsonValue + ')');
    var jsonObj = jQuery.parseJSON(HfJsonValue);

and my page looks like this

 <div id="Pagination" class="page-numbers"></div>
  <br style="clear:both;" />
  <div id="Searchresult"></div>

  <div id="hiddenresult" style="display:none;">

  </div>
 <script type="text/javascript">
     var pagination_options = {
         num_edge_entries: 2,
         num_display_entries: 8,
         callback: pageselectCallback,
         items_per_page: 3
     }
     function pageselectCallback(page_index, jq) {
         var items_per_page = pagination_options.items_per_page;
         var offset = page_index * items_per_page;
         var new_content = $('#hiddenresult div.resultsdiv').slice(offset, offset + items_per_page).clone();
         $('#Searchresult').empty().append(new_content);
         return false;
     }
     function initPagination() {
         var num_entries = $('#hiddenresult div.resultsdiv').length;
         // Create pagination element
         $("#Pagination").pagination(num_entries, pagination_options);
     }
     $(document).ready(function() {
         Iteratejsondata();
         initPagination();
     });
</script>

I have inspected through Firebug and saw all jQuery files have been downloaded but why is this happening?

Answer 1

You can also use JSON.parse(). Its natively supported on FF, Chrome,Safari and IE8 and is most likely going to be faster than the JQuery version.

If you are targeting IE7 and IE6, JQuery would be the best bet.

Answer 2

I also ran into this error but it was due to an old javascript library I was using along with jQuery 3.

As of jQuery 3+ jQuery.parseJson has been deprecated in favor of the native JSON.parse that has the same browser support as jQuery 3
