如何在angular JS中获取剪贴板数据 [英] how to get clipboard data in angular JS

问题描述

我实际上是想使用 angular JS 来获取剪贴板的内容来模拟复制粘贴的东西.

I was actually looking to get the content of clipboard using angular JS to simulate a copy paste thing.

推荐答案

我创建了一个用于复制到剪贴板的指令，该指令使用 document.execCommand() 方法.

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

指令

(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>
