Clipboard.js 循环按钮

Clipboard.js loop buttons

我使用 clipboard.js,点击其中一个按钮后,我想在按钮下方显示一条成功消息,但我无法循环。

这是按钮:

<button type="button" class="clipboard-button button-rect" data-clipboard-text="{{ site.author.email|safe_email }}">
  <span class="button-text">Get in touch</span>
  <span class="clipboard-message">My E-Mail has been copied</span>
</button>

这是 js:

var clipboard = new ClipboardJS('.clipboard-button');

clipboard.on('success', function () {
    var message = document.querySelectorAll('.clipboard-message');
    message.style.opacity = '1';
    setTimeout(function () {
        message.style.opacity = '0';
    }, 2000);
});

我想在按下的按钮下方显示消息,而不是为每个按钮显示消息。

非常感谢您的帮助,我已经尽力了。顺便说一句,我是 JS 初学者,所以请耐心等待。 :)

您应该注意的是实现检索单击的 DOM 元素(在本例中为按钮)。然后很容易找到相应的 .clipboard-message span 元素。

要检索单击的元素,您可以使用提供给 success 事件回调函数的参数,如下所述:https://clipboardjs.com/#events

然后你的JavaScript代码变成:

var clipboard = new ClipboardJS('.clipboard-button');

clipboard.on('success', function (e) {
    // e.trigger corresponds to the clipboard-button DOM element that triggered the event
    // You can then use querySelector(...) to retrieve to first child element with the class clipboard-message
    var message = e.trigger.querySelector('.clipboard-message');
    message.style.opacity = '1';
    setTimeout(function () {
        message.style.opacity = '0';
    }, 2000);
});

这里有一个工作代码片段供您尝试:

var clipboard = new ClipboardJS('.clipboard-button');

clipboard.on('success', function (e) {
    var message = e.trigger.querySelector('.clipboard-message');
    message.style.opacity = '1';
    setTimeout(function () {
        message.style.opacity = '0';
    }, 2000);
});
.clipboard-message {
    color: green;
    opacity: 0;
}
