Question

进一步提出这个问题：
Copy to clipboard with jQuery/js in Chrome

上述问题的代码非常适合用javascript将字符串复制到剪贴板，但是我需要从用户点击注入元素来触发该过程。出于某种原因，如果注入元素，代码将无法工作。有人可以让我直截了当吗？

在下面的代码示例中，我添加了一个红色？按钮并将其添加到身体上。请注意，单击它不会将所需的文本复制到剪贴板。倒q'hy？有什么想法吗？

Answer 1

使用win = new BrowserWindow({width: 800, height: 600}) const template = [ { label: 'Custom', submenu: [ { label: 'navigate', click () { win.loadURL('https://electron.atom.io'); } } ] } ] const menu = Menu.buildFromTemplate(template) Menu.setApplicationMenu(menu) // and load the index.html of the app. win.loadURL(url.format({ pathname: path.join(__dirname, 'index.html'), protocol: 'file:', slashes: true }))获取原始事件，而不是jQuery事件对象

＆＃13;

e.originalEvent.clipboardData

＆＃13;

var elem = document.getElementById('test');
var elem2 = document.getElementById('test2');
var elem3 = document.getElementById('test3');
elem.onmouseup = function () {
    document.execCommand('copy');
}

elem2.addEventListener('copy', function (e) {
    e.preventDefault();
    if (e.clipboardData) {
        e.clipboardData.setData('text/plain', 'custom content');
    } else if (window.clipboardData) {
        window.clipboardData.setData('Text', 'custom content');
    }

});

elem3.onclick = function () {
    document.execCommand('copy');
}

elem3.addEventListener('copy', function (e) {
    e.preventDefault();
    if (e.clipboardData) {
        e.clipboardData.setData('text/plain', 'bonk custom contentt');
    } else if (window.clipboardData) {
        window.clipboardData.setData('Text', 'bonkcustom content from click');
    }
});
$('body').prepend('<div id="test4" title="Click to copy text RAINBOX to clipboard">?</div>');
$(document).on('click', '#test4', function(e){
    document.execCommand('copy');
});
$(document).on('copy', '#test4', function(e){
    e.preventDefault();
    if (e.originalEvent.clipboardData) {
        e.originalEvent.clipboardData.setData('text/plain', 'Over the rainbox');
    } else if (window.clipboardData) {
        window.clipboardData.setData('Text', 'Rainbox');
    }
});

Answer 2

您需要将on事件发送到动态创建的元素。试试这个：

$('#test4').on("click", function() {
  //Your copy code  here
});

通过单击注入的元素将javascript复制到剪贴板
