you have call getfoodmenudata(), , inside callback asynchronous $.getjson, call showfoodmenudata().

function getfoodmenudata() {   var url = 'http://localhost:8888/tom_carp_final_project/chorizios/foodmenu.json';   $.getjson(url, function(data) {     window.localstorage.setitem('choriziosmenu333', json.stringify(data));     showfoodmenudata(); // <--- call inside callback   }); }  function showfoodmenudata() {   var data = json.parse(window.localstorage.getitem('choriziosmenu333'));   var images = "";   $.each(data.menu, function() {     images += '<li class="list-group-item"><img style="width: 100%;" src= "' + this.url + '"></li>';     images += '<li class="list-group-item">' + this.description + '</li>';   });   $('#foodmenu').append(images); }  getfoodmenudata(); // <--- call first
