It's interesting to see a simple Todo app on the web today, using ANGULARJS to do front-end data binding and using Localstorage to store data.

Ng-app declares the use of Todoapp as model

Ng-controller declares Todocontroller as the controller

Ng-model= "Note" Data is bound to the input box, which is bound to the $scope.note

ng-click= "Createnote" binds a function (object), bound to $scope.createnote = function () {...}

Ng-repeat = "Note in Notes track by $index" and {{Note}} does not look familiar, right, is the ANGULARJS loop traversal, listing all the notes array of data

The following is Todoapp JS Kurding, controller ' Todocontroller ' incoming $scope and notesfactory services,

Object.keys Traverse all the Key-value key pairs in the Localstorage

varTodoapp = Angular.module (' Todoapp '), []); Todoapp.controller (' Todocontroller ',function($scope, notesfactory) {$scope. Notes=Notesfactory.get (); $scope. Createnote=function() {notesfactory.put ($scope. Note); $scope. Note= ' '; $scope. Notes=Notesfactory.get (); }}); Todoapp.factory (' Notesfactory ',function(){    return{put:function(note) {Localstorage.setitem (' Todo ' + (Object.keys (localstorage). length + 1), note); }, get:function(){        varNotes = []; varKeys =Object.keys (localstorage);  for(vari = 0; i < keys.length; i++) {Notes.push (Localstorage.getitem (keys[i)); }        returnnotes; }           };})

BTW, through the Firefox developer Tool can see the changes to delete the current page of localstorage content, specific methods please poke here

The last thing I want to say is that Angularjs is really a good stuff.
