Ionic Framework web services loop $http json request

Web Services Loop $http json request

Today Discussed Ionic Framework web Services data looping Concepts. Angularjs Previously discussed angularjs looping concepts same based ionic framework used. Angularjs and Ionic Framework is same concepts. Here follows this sample code in ionic framework and more information and example click here



controller('DataCtrl', function($scope, $http, data) {
  $scope.name = 'World';
  $scope.allads = [];
  $scope.data= [];

  $http.get('http://www.mysite.com/list.json').success(function(data) {
    $scope.allads = data;
    $scope.loadMore();
  });

  var counter = 0;

  $scope.loadMore = function() {
    var data = [];
    var l = $scope.data.length;
    var m = Math.min(l+10, $scope.allads.length);
    for ( var i = l; i < m; i++) {
      data.push($scope.allads[i]);
    }

    console.log('Loading more!', m);
    $scope.ads = $scope.ads.concat(data);
    $scope.$broadcast('scroll.infiniteScrollComplete');
  };

  $scope.$on('stateChangeSuccess', function() {
    $scope.loadMore();
  });

  // THIS METHOD LOADS 4 LOCAL TEST ITEMS WITH THE ADSSERVICE
  //$scope.ads = ads;
})

and
.service('AdsService', function($q) {

  return {
    ads : [
        { shortrelativetime:'30 min ago', title: 'TST อาหารเสริมเพี่มความสูง', group:'Vehicles', category:'Cars', province:'Vientiane Capital', district:'Xaythany', price:'24000', currency:'USD', photo:'20140202-040753-c1395444fd.jpg', id: 1 },

    ],
    getAds: function() {
        return this.data
    },
    getAd: function(adId) {
        var dfd = $q.defer()
        this.ads.forEach(function(ad) {
            if (ad.id === adId) dfd.resolve(ad)
        })

        return dfd.promise
    }

  }

ionic framework Making a Signature Drawpad

Ionic Framework Making a Signature Drawpad today discussed this task is Recently I was working on some app and wanted an opportunity for the user to write something down. As I was working with the html5 canvas, I found a very good looking library which I want to show you today: The signature pad. This library allows to draw on your device, with not just a normal bold line but with a quite realistic appeal. Let’s make a simple app to test it!

ionic framework Making a Signature Drawpad

Setup a simple App


ionic start devdactic-signature blank

cd devdactic-signature

bower install --save signature_pad

I like to install those packages whenever possible through bower, as it makes managing those dependencies a lot easier. As bower will install our libs always to the same folder, we can go ahead and include the js file at the top of our index.html file:


<script src='lib/signature_pad/signature_pad.js'></script>

Include the Signature Pad functionalities

To use the library, we must define a canvas element inside our index.html which will be the area for the user to draw his signature (or anything else). For this tutorial, we will just have a tiny area at the top, which has the signatureCanvas id so we can get it later in our controller. Additionally I created 2 buttons, which can clear the area or save the current content of the area. Below we have a image, which will show our last saved signature from the canvas. So go ahead and replace everything inside the body with this:

<body ng-app='starter' ng-controller='SignatureCtrl'>
 
    <ion-pane>
      <ion-header-bar class='bar-calm'>
        <h1 class='title'>Devdactic Signature Drawpad</h1>
      </ion-header-bar>
 
      <ion-content class='has-header padding' scroll='false'>
          <canvas id='signatureCanvas' width='300' height='180' style='border: 1px solid black;'></canvas>
          <div class='button-bar'>
              <a class='button button-energized' ng-click='clearCanvas()'>Clear</a>
              <a class='button button-balanced' ng-click='saveCanvas()'>Save</a>
          </div>
          <br>
          <img ng-src='{{signature}}'/>
      </ion-content>
    </ion-pane>
  </body>

We have now defined everything we need inside our index, now we will create the controller which will use the signature pad functionality. Open your app.js and add this:

.controller('SignatureCtrl', function($scope) {
    var canvas = document.getElementById('signatureCanvas');
    var signaturePad = new SignaturePad(canvas);
 
    $scope.clearCanvas = function() {
        signaturePad.clear();
    }
 
    $scope.saveCanvas = function() {
        var sigImg = signaturePad.toDataURL();
        $scope.signature = sigImg;
    }
})

First of all, we get our canvas element through our defined id. Afterwards, we create a new SignaruePad from our canvas element. Now we can simply call functions on this element, thats all! Our clearCanvas() will, well, obviously just clear the canvas drawing area, and our saveCanvas() function gets the image data from the canvas by calling the toDataURL() on our signature pad. This info can be directly used to update our image below.

These are just some simple functions, there are some more things you can edit, which include:

dotSize – Size of dot
minWidth – Minimum size of a line
maxWidth – Maximum sizw of a line
backgroundColor – Color used when the canvas is cleared
penColor – Color of your line
onBegin & onEnd – Callback functions

Ionic Framework Session Controller

Ionic Framework Session

Ionic Framework Session Controller is two controllers you create in this module use the Session service defined in the starter.services module. To add starter.services as a dependency to the starter.controller module:

Open conference/www/js/controllers.js
Add starter.services as a dependency to make the Session service available to the controllers:

angular.module('starter.controllers', ['starter.services'])

Implement the Session

In controllers.js, delete PlayListsCtrl (plural)
Replace it with a controller named SessionsCtrl that retrieves the list of conference sessions using the Session service and stores it in a scope variable named sessions:

.controller('SessionsCtrl', function($scope, Session) {
    $scope.sessions = Session.query();
})

.controller('SessionCtrl', function($scope, $stateParams, Session) {
    $scope.session = Session.get({sessionId: $stateParams.sessionId});
});
