いまの時代、JavaScript側でQRコードを生成できるんですね

Last updated at Posted at 2014-08-21

ということで、試してみた。手を抜くために、angular-qr というのを使いました。

結果(デモ)

導入手順

前提

手順(AngularJSの雛型の生成後)

  • Bower で angular-qr をインストール

     $ bower install angular-qr --save
    
  • $ grunt bower-install とするか、もしくは index.html に下記を追記します。

    app/index.html
     <script src="bower_components/qrcode/lib/qrcode.js"></script>
     <script src="bower_components/angular-qr/src/angular-qr.js"></script>
    
  • AngularJS に組み込み

    app/scripts/app.js
     'use strict';
     
     angular.module('qrTestApp', [
       'ngCookies',
       'ngResource',
       'ngSanitize',
       'ngRoute',
     +  'ja.qr'
     ])
     〜
    
  • この状態で使えるようになっているはずなので、後は Controller と View を書きます。

    app/scripts/controllers/main.js
     'use strict';
     
     angular.module('qrTestApp')
       .controller('MainCtrl', ['$scope', function ($scope) {
     
         $scope.string = '';
     
       }]);
    
    app/views/main.html
     <div ng-controller="MainCtrl">
         <div class="header">
           <h3 class="text-muted">QRコードのテスト</h3>
         </div>
         <p>
             <input type="text" placeholder="http:// ※日本語はNG" size="30" ng-model="string">
         </p>
         <br>
         <p>
             <qr text="string" size="150"></qr>
         </p>
     </div>
    
  • 以上!
