我正在使用backbone.js 创建一个联系人管理器,这是我的代码
$(document).ready(function() {
var Contact=Backbone.Model.extend({
defaults: {
fname : '',
lname : '',
phoneno : ''
}
});
var ContactList=Backbone.Collection.extend({
model : Contact,
localStorage: new Store("ContactList-backbone")
});
var ContactView=Backbone.View.extend({
el : $('div#contactmanager'),
events: {
'click #additems' : 'add'
},
initialize: function() {
this.render();
this.collection = new ContactList();
},
add : function() {
s1=$('#fname').val();
s2=$('#lname').val();
s3=$('#phoneno').val();
if(s1 =="" || s2=="" || s3=="")
{
alert("Enter values in Textfield");
}
else
{
$('#tlist').append("<tr><td>"+s1+"</td><td>"+s2+"</td><td>"+s3+"</td> </tr>");
cont=new Contact({fname:s1,lname:s2,phoneno:s3});
this.collection.add(cont);
cont.save();
}
},
render : function() {
$(this.el).append("<label><b>First Name</b></label><input id= 'fname' type='text' placeholder='Write ur first name'></input>");
$(this.el).append("<br><label><b>Last Name</b></label><input id= 'lname' type='text' placeholder='Write ur last name'></input>");
$(this.el).append("<br><label><b>Phone Number</b></label><input id= 'phoneno' type='text' placeholder='Write ur phone number'></input>");
$(this.el).append("<br><button id='additems'>ADD</button>");
var showdata=localStorage.getItem('ContactList-backbone',this.model);
console.log(showdata,"showdata");
}
return this;
},
});
var contactManager=new ContactView();
});
这就是我使用本地存储的方式
function S4() {
return (((1+Math.random())*0x10000)|0).toString(16).substring(1);
};
function guid() {
return (S4());
};
var Store = function(name)
{
this.name = name;
var store = localStorage.getItem(this.name);
this.data = (store && JSON.parse(store)) || {};
};
_.extend(Store.prototype,
{
save: function() {
localStorage.setItem(this.name, JSON.stringify(this.data));
},
create: function(model) {
if (!model.id) model.id = model.attributes.id = guid();
this.data[model.id] = model;
this.save();
return model;
},
Backbone.sync = function(method, model, options) {
var resp;
var store = model.localStorage || model.collection.localStorage;
switch (method) {
case "create": resp = store.create(model); break;
//I am using only create
}
if (resp) {
options.success(resp);
}
else {
options.error("Record not found");
}
};
数据存储在本地存储中。但是当页面重新加载时,我无法弄清楚如何在我的表格中显示这些数据。例如:我想在表格中显示名字、lname 和电话号码;我是骨干新手,所以请帮助我
