Install Git for Windows

 

  • When you’ve successfully started the installer, you should see the Git Setup wizard screen. Follow the Next and Finish prompts to complete the installation. The default options are pretty sensible for most users.

 

  • Open a Command Prompt (or Git Bash if during installation you elected not to use Git from the Windows Command Prompt).

 




  • Run the following commands to configure your Git username and email using the following commands, replacing Jyothish name with your own. These details will be associated with any commits that you create.

$ git config --global user.name "Jyothish"
$ git config --global user.email "jyothish@mypassionmydreams.com"

 

simple Notepad application in ionic V1 and and AngularJS

Before We Get Started

Before you go through this tutorial, you should have at least a basic understanding of Ionic concepts. You must also already have Ionic installed on your machine.

So, to that end, we will be building a Notepad application that will allow a user to:

  • View a list of Notes
  • Add new Notes
  • Save the Notes to permanent storage

We will start with a blank ionic template.So First install the Ionic blank template.

Open your Git cmd and type the run the following command to generate a new Ionic application.

If your system does not have Git installed ,install it.Follow my tutorial for installation. Git For Windows

ionic start NotePad blank

The Ionic Start command will create a folder named NotePad and setup the Ionic files and folders.

Add the Cordova project for the Android Platform and install the basic Cordova plugins as explained above.

cd Notepad
ionic platform add android

Add the Sqlite plugin to the android project.Sqlite is used to store the data for Notepad app.

cordova plugin add https://github.com/litehelpers/Cordova-sqlite-storage.git

Build ionic project

ionic build android

Open your newly created project using android studio (you can use your own IDE).

In android studio.File>Open>select Your Folder where ionic project is present.Select android folder from it and click ok.

Create template folder in the www>templates (Create template folder in the android>asset>www>templates in android studio)

Change your index.html into

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

      if ('serviceWorker' in navigator) {
        navigator.serviceWorker.register('service-worker.js')
          .then(() => console.log('service worker installed'))
          .catch(err => console.log('Error', err));

  </head>
  <body ng-app="starter" class="platform-android platform-cordova platform-webview">

  <ion-nav-view>

  </ion-nav-view>
  </body>
</html>

 

Look into index.html

We add 3 hidden field named hfTemp,hfCheck and hfNoteValue in the index file.Use of it will explained later.

We use two html pages one Main page where you can see your data you add in notepad,here i named as Home.html.Another page for editing or adding text in  notepad,here i named as editor.html.

Create a new html file in templates folder named Home.html .Copy the below code.

<ion-view   >

  </div>  <div class="bar bar-header bar-positive">
        <button class="button" ng-click="Add()">Add</button>
        <h1 class="title">Notepad</h1>
    </div>
    <ion-content class="note" direction="y">

    <div ng-repeat="Notemessage in details" class="list card animated infinite " style="opacity: 0.4;"  >
        <div class="item item-divider" style="color:red;"></div>
        <button class="button button-small-light" ng-click="Delete(Notemessage)">Delete</button>
        <div  class="item item-body" ng-click="watch(Notemessage.id)">
            <div >
             <p>{{Notemessage.message}}</p>
            </div>
        </div>
    </div>


    </ion-content>
</ion-view>

It contains an Add button which is used to add new text file to the notepad.

ng-repeat is used to show all the text field you have added. 

Create a new html file in templates folder named editor.html.

<ion-view  >


    <div class="bar bar-header bar-positive">
        <button class="button" ng-click="Confirm(edit)">Add</button>
        <h1 class="title">Notepad</h1>
    </div>

<textarea class="editorcss" rows="25" ng-model="edit"  id="textset" cols="50" ng-bind="update"  placeholder="Enter text here..." style="width:355px;font-size:25px;background-color: rgba(255, 255, 255, .4);">
</textarea>
    <h1>{{Notemessage}}</h1>
</ion-view>

It Consist of textarea and an Add button to add file .

Change your style.css into

/* Empty. Add your own CSS if you like */
.test
{
margin-top:50px;

}
.imag1
{
width:350px;

}

.main1
{
margin-top:150px;
}

.item.item-input {
    background-color: transparent;
    color:#fff;
}
.editorcss

{
margin-top:45px;
}
.note
{
margin-top:40px;
}

Download ng-cordova.min.js and copy it in js page.We already specified it in index.html page

Change your app.js into

// Ionic Starter App


angular.module('starter', ['ionic','starter.controller','ngCordova'])


.run(function($ionicPlatform,$cordovaSQLite,$rootScope,$ionicSideMenuDelegate,$state,$ionicHistory,$ionicPopup) {
  $ionicPlatform.ready(function() {

    if(window.cordova && window.cordova.plugins.Keyboard) {
      // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
      // for form inputs)
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

      // Don't remove this line unless you know what you are doing. It stops the viewport
      // from snapping when text inputs are focused. Ionic handles this internally for
      // a much nicer keyboard experience.
      cordova.plugins.Keyboard.disableScroll(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();

    }
var db;
 db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
               $cordovaSQLite.execute(db, 'CREATE  TABLE IF NOT EXISTS Note (id INTEGER PRIMARY KEY AUTOINCREMENT, message TEXT)');

 $ionicPlatform.registerBackButtonAction(function(e){
    document.getElementById('hfTemp').value="test";

      e.preventDefault();
     if ($state.is('Home')) {
          navigator.app.exitApp();
            }
    else{
       $state.go('Home');
       }
      return false;
    },101);
});
})


.config
(function($stateProvider, $urlRouterProvider) {
 $stateProvider
 .state('editor', {
            url: '/editor',
        cache: false,
            templateUrl: 'templates/editor.html',
   controller: 'EditCtrl'
        })

    .state('Home', {
        url: '/Home',
    cache: false,
        templateUrl: 'templates/Home.html',
      controller: 'HomeCtrl'
    });
 $urlRouterProvider.otherwise('/Home');
});

Explanation

In app.js we created our database and table.I named database as Test.db.Then i created a table named Note having field id and message .

var db;
 db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
 $cordovaSQLite.execute(db, 'CREATE  TABLE IF NOT EXISTS Note (id INTEGER PRIMARY KEY AUTOINCREMENT, message TEXT)');

Then we config our back button.If  the app is in Home page then exit the app.Otherwise it go Home page.

$ionicPlatform.registerBackButtonAction(function(e){
    document.getElementById('hfTemp').value="test";

      e.preventDefault();
     if ($state.is('Home')) {
          navigator.app.exitApp();
            }
    else{
       $state.go('Home');
       }
      return false;
    },101);
});

Then define the 2 page we created in templates folder.

.config
(function($stateProvider, $urlRouterProvider) {
 $stateProvider
 .state('editor', {
            url: '/editor',
        cache: false,
            templateUrl: 'templates/editor.html',
   controller: 'EditCtrl'
        })

    .state('Home', {
        url: '/Home',
    cache: false,
        templateUrl: 'templates/Home.html',
      controller: 'HomeCtrl'
    });
 $urlRouterProvider.otherwise('/Home');
});

Add a controller.js in the js folder and copy the below code in it.

angular.module('starter.controller', [])
.controller('EditCtrl', function($scope,$stateParams,$cordovaSQLite,$ionicPlatform,$state) {
  $ionicPlatform.ready(function() {
  document.getElementById('hfCheck').value="CHECK";
  val1=document.getElementById('hfNoteValue').value;

  if(val1!=null)
  {
   vartemp=document.getElementById('hfTemp').value;
    if(vartemp=="SET")
     {
       db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
          var query=  "SELECT * FROM Note WHERE id= ?"
                 $cordovaSQLite.execute(db, query, [val1])
                   .then(
                   function(result) {
                      $scope.edit = result.rows.item(0).message;
                     /* document.getElementById('hfTemp').value="SET";*/
                   },
                   function(error) {
                   }
               );
           }
}
});
   $scope.Confirm= function(edit){
    vartemp=document.getElementById('hfTemp').value;
     if(vartemp!="SET")
         {
     db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
    $cordovaSQLite.execute(db, 'INSERT INTO Note (message) VALUES (?)', [edit])
        .then(function(result) {
         //   $scope.statusMessage = "Message saved successful, cheers!";
               $state.go('Home',{});
        }, function(error) {
         //   $scope.statusMessage = "Error on saving: " + error.message;
        })
}
  if(vartemp=="SET")
   {
     val1=document.getElementById('hfNoteValue').value;
    db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});

    var query =   "UPDATE  Note SET message='"+edit+"' WHERE id=?";
              $cordovaSQLite.execute(db, query,[val1])
             .then(function(result) {
               document.getElementById('hfTemp').value="test";
               $state.go('Home',{});
          }, function(error) {
     //   $scope.statusMessage = "Error on saving: " + error.message;
         });
   }
  };

})


.controller('HomeCtrl', function($scope,$stateParams,$cordovaSQLite,$ionicPlatform,$state,$ionicPopup) {
$ionicPlatform.ready(function() {
 document.getElementById('hfCheck').value="CHECK";
 $scope.details = [];
  db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
    $cordovaSQLite.execute(db, 'SELECT * FROM Note ORDER BY id DESC')
               .then(
                   function(result) {
                     if (result.rows.length > 0) {
                        for(var i = 0; i < result.rows.length; i++)
                       {
                         $scope.details.push({id: result.rows.item(i).id, message: result.rows.item(i).message});
                       }

                            }
                                },
                  function(error) {
                   $scope.statusMessage = "Error on loading: " + error.message;
                   }
               );
               });
   $scope.Delete= function(Notemessage){
        var confirmPopup = $ionicPopup.confirm({
           title: 'Delete',
           template: 'Are you sure?'
        });

        confirmPopup.then(function(res) {
           if(res) {
              console.log('Sure!');
                     db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
                            var query =   "DELETE  FROM Note WHERE  id = ?";
                            $cordovaSQLite.execute(db, query, [Notemessage.id]).then(function(res) {
                                $scope.details.splice($scope.details.indexOf(Notemessage), 1);
                            }, function (err) {
                                 $scope.statusMessage = "Error on loading: " + err.message;
                            });
           } else {
              console.log('Not sure!');
           }
        });

    }
 $scope.Add = function() {
   document.getElementById('hfTemp').value="test";
   $state.go('editor',{});
     }
  $scope.watch=function(val)
    {
  document.getElementById('hfTemp').value="SET";
  document.getElementById('hfNoteValue').value=val;
   $state.go('editor',{});
  }

});






Explanation

Define two controllers named HomeCtrl and EditCtrl.

Within the HomeCtrl.

Select all the data from table Note  using the query ‘SELECT * FROM Note ORDER BY id DESC’ and show in the Home.html using ng-repeat.

$ionicPlatform.ready(function() {
 document.getElementById('hfCheck').value="CHECK";
 $scope.details = [];
  db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
    $cordovaSQLite.execute(db, 'SELECT * FROM Note ORDER BY id DESC')
               .then(
                   function(result) {
                     if (result.rows.length > 0) {
                        for(var i = 0; i < result.rows.length; i++)
                       {
                         $scope.details.push({id: result.rows.item(i).id, message: result.rows.item(i).message});
                       }

                            }
                                },
                  function(error) {
                   $scope.statusMessage = "Error on loading: " + error.message;
                   }
               );
               });

Delete the data you add using the code.

 $scope.Delete= function(Notemessage){
        var confirmPopup = $ionicPopup.confirm({
           title: 'Delete',
           template: 'Are you sure?'
        });

        confirmPopup.then(function(res) {
           if(res) {
              console.log('Sure!');
                     db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
                            var query =   "DELETE  FROM Note WHERE  id = ?";
                            $cordovaSQLite.execute(db, query, [Notemessage.id]).then(function(res) {
                                $scope.details.splice($scope.details.indexOf(Notemessage), 1);
                            }, function (err) {
                                 $scope.statusMessage = "Error on loading: " + err.message;
                            });
           } else {
              console.log('Not sure!');
           }
        });

    }

For adding a file click on the Add button.Here i used hfTemp hidden field.It is used to differentiate the editor page whether it is an update or add a new file.

For New file hfTemp= test

$scope.Add = function() {
   document.getElementById('hfTemp').value="test";
   $state.go('editor',{});
     }

Watch is used to navigate to editor.html file when we click on the text file..Here i used hfTemp hidden field.It is used to differentiate the editor page whether it is an update or add a new file.

For update hfTemp= SET

$scope.watch=function(val)
  {
 document.getElementById('hfTemp').value="SET";
 document.getElementById('hfNoteValue').value=val;
 $state.go('editor',{});
}

In EditCtrl

If the hidden field value id Set Then Updatation

if(vartemp=="SET")
     {
       db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
          var query=  "SELECT * FROM Note WHERE id= ?"
                 $cordovaSQLite.execute(db, query, [val1])
                   .then(
                   function(result) {
                      $scope.edit = result.rows.item(0).message;
                     /* document.getElementById('hfTemp').value="SET";*/
                   },
                   function(error) {
                   }
               );
           }
if(vartemp=="SET")
 {
   val1=document.getElementById('hfNoteValue').value;
  db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});

  var query =   "UPDATE  Note SET message='"+edit+"' WHERE id=?";
            $cordovaSQLite.execute(db, query,[val1])
           .then(function(result) {
             document.getElementById('hfTemp').value="test";
             $state.go('Home',{});
        }, function(error) {
   //   $scope.statusMessage = "Error on saving: " + error.message;
       });
 }

If hidden field not equal SET then insert

 if(vartemp!="SET")
         {
     db = $cordovaSQLite.openDB({name:"Test.db", location:'default'});
    $cordovaSQLite.execute(db, 'INSERT INTO Note (message) VALUES (?)', [edit])
        .then(function(result) {
         //   $scope.statusMessage = "Message saved successful, cheers!";
               $state.go('Home',{});
        }, function(error) {
         //   $scope.statusMessage = "Error on saving: " + error.message;
        })
}

 

Then build and run your project

 ionic run android

Note:Copy all files from NotePad\platforms\android\assets\www into Notepad\www
(If you are developing using android studio).

Then Build ionic project.

Your notepad app is ready.

Check the app in playstore Notepad app

Download the code From Ionic Market or From GitHub
