Question

我有一个问题，当我尝试多重警报时，我看到所有结果都相同（所有数据都是＆＃34; 1＆＃34;）。我想要：

如果点击按钮number1 =＆gt; alert：1
如果点击按钮number2 =＆gt;警告：2
如果点击按钮number3 =＆gt;警告：3

我附上了一张关于我的问题的照片

Answer 1

更改此行

var test = $(".btn").attr("data-clipboard-text");

用这个

var test = e.text;

实例化剪贴板并且copy事件成功后，事件的文本e.text基本上是点击按钮的data-clipboard-text属性的值。

	var clipboard = new Clipboard('button');
	// once text is copied to clipboard
	clipboard.on('success', function(e) {
        // event action "copy"
        // event text "e.text" now has the value of data-clipboard-text attribute
		//console.log(e);
		var test = e.text;
		alert (test + " : was copy on clipboard");
	});

	clipboard.on('error', function(e) {
		console.log(e);
	});

Answer 2

试试这个：

＆＃13;

var clipboard = new Clipboard('.btn');
	
	clipboard.on('success', function(e) {
		console.log(e);
		var test = e.text;
		alert (test + " : was copy on clipboard");
	});

	clipboard.on('error', function(e) {
		console.log(e);
	});

<script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/1.6.1/clipboard.min.js"></script>
<button class="btn" data-clipboard-text="1">Copy</button>
<button class="btn" data-clipboard-text="2">Copy</button>
<button class="btn" data-clipboard-text="3">Copy</button>
