我無法save gender data和無法delete particular data or clear all data。我想使用html5 localStorage創建一個聯繫表單。但沒有工作刪除和刪除所有按鈕？也無法保存性別數據
$(document).ready(function() {
contactsNamespace.initialize();

ns.display();
};
function retrieveFromStorage() {
var contactsJSON = localStorage.getItem('contacts');
return contactsJSON ? JSON.parse(contactsJSON) : [];
}
ns.display = function() {
$('#currentAction').html('Add Contact');
currentRecord = { key: null, contact: {} };
displayCurrentRecord();
var results = retrieveFromStorage();
bindToGrid(results);
};
function bindToGrid(results) {
var html = '';
for (var i = 0; i < results.length; i++) {
var contact = results[i];
html += '<tr><td>' + contact.email + '</td>';
html += '<td>' + contact.firstName + ' ' + contact.lastName + '</td>';
html += '<td><a class="edit" href="javascript:void(0)" data-key=' + i + '>Edit</a>' + '|' + '<a class="delete" href="javascript:void(1)" data-key=' + i + '>Delete</a></td></tr>';
