how to get clipboard data in angular JS

I created a directive for copy to clipboard which is using the document.execCommand() method.

Directive

(function() {
app.directive('copyToClipboard',  function ($window) {
        var body = angular.element($window.document.body);
        var textarea = angular.element('<textarea/>');
        textarea.css({
            position: 'fixed',
            opacity: '0'
        });

        function copy(toCopy) {
            textarea.val(toCopy);
            body.append(textarea);
            textarea[0].select();

            try {
                var successful = document.execCommand('copy');
                if (!successful) throw successful;
            } catch (err) {
                console.log("failed to copy", toCopy);
            }
            textarea.remove();
        }

        return {
            restrict: 'A',
            link: function (scope, element, attrs) {
                element.bind('click', function (e) {
                    copy(attrs.copyToClipboard);
                });
            }
        }
    })
}).call(this);    

Html

<button  copy-to-clipboard="Copy Me!!!!" class="button">COPY</button> 

here's a concise version I use -

function copyToClipboard(data) {
    angular.element('<textarea/>')
        .css({ 'opacity' : '0', 'position' : 'fixed' })
        .text(data)
        .appendTo(angular.element($window.document.body))
        .select()
        .each(function() { document.execCommand('copy') })
        .remove();
}

BTW, if using Angular to copy to clipboard with a Chrome Packaged App, do the following:

1. Add "clipboardRead" and "clipboardWrite" to the "permissions" in the manifest.json.
2. use ng-click in your view to feed the value to the controller $scope, like: data-ng-click="copyUrlToClipboard(file.webContentLink)"

3. Put a function in your controller like:

   $scope.copyUrlToClipboard =  function(url) {
       var copyFrom = document.createElement("textarea");
       copyFrom.textContent = url;
       var body = document.getElementsByTagName('body')[0];
       body.appendChild(copyFrom);
       copyFrom.select();
       document.execCommand('copy');
       body.removeChild(copyFrom);
       this.flashMessage('over5');
   }

I had the same issue and I used angular-clipboard feature[1] which uses new Selection API and Clipboard API available in the latest browsers.

First we have to install angular-clipboard lib, i'm using bower.

$ bower install angular-clipboard --save

To import the module use following in html.

<script src="../../bower_components/angular-clipboard/angular-clipboard.js"></script>

To set values to element using $scope in controller

$scope.textToCopy = 'Testing clip board';

Load the clipboard module using,

angular.module('testmodule', ['angular-clipboard']);

This works for Chrome 43+, Firefox 41+, Opera 29+ and IE10+.

Its simple & worked fine.

Thanks,

A completely different approach:

I need to copy & paste text between windows, so I used this to save (copy) the data to local storage. Then, in the other window, I load it out of local storage, using the same key, and I can then 'paste' is as I like.
