我使用剪贴板.js,单击我的一个按钮后,我想在该按钮下显示一条成功消息,但我无法遍历整个循环。
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,而不是每个按钮都显示。
感谢您的帮助,我做了很多尝试。我是JS初学者,所以请耐心等待。 :)

您应该看的是实现检索单击的DOM元素(在这种情况下为按钮)。这样就很容易找到对应的.clipboard-message
span元素。
要检索被单击的元素,可以使用赋予success
事件回调函数的参数,如此处所述:https://clipboardjs.com/#events
然后您的JavaScript代码变为:
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);
});
这是一个工作代码段供您尝试:
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;
}
