Default Chapter 34 Files


i follows the filereader API practice from page 304 to page 307, but my code does not seem to work, the error message is "Uncaught TypeError: this.store is not a function"

the following is the code i entered:

$(screen).find('#importJSONFile').change(function( evt) {
var reader = new FileReader();
reader.onload = function(evt) {
var contacts = JSON.parse(evt.target.result);
for (var i = 0; i < contacts.length; i++) {

and i think this is my store function:

function store(contact) {
var contactsStored = localStorage.getItem('contacts');
var contacts = [];
if (contactsStored) {
contacts = JSON.parse(contactsStored);
localStorage.setItem('contacts', JSON.stringify(contacts));

Please let me know how to rectify this.

Many thanks in advance
