（2）clipboard复印内容的方式
从target复印目标内容通过function 要复印的内容通过属性返回复印的内容（3）clipboard使用实例
从target复印目标内容：
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8" /><title>target-div</title><meta name="viewport" content="width=device-width, initial-scale=1" /></head><body><!-- 1. Define some markup --><div>hello</div><buttonclass="btn"data-clipboard-action="copy"data-clipboard-target="div">Copy</button><!-- 2. Include library --><script src="../dist/clipboard.min.js"></script><!-- 3. Instantiate clipboard --><script>var clipboard = new ClipboardJS('.btn');clipboard.on('success', function (e) {console.log(e);});clipboard.on('error', function (e) {console.log(e);});</script></body></html>
通过function 要复印的内容：
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8" /><title>function-text</title><meta name="viewport" content="width=device-width, initial-scale=1" /></head><body><!-- 1. Define some markup --><button class="btn">Copy</button><!-- 2. Include library --><script src="../dist/clipboard.min.js"></script><!-- 3. Instantiate clipboard --><script>var clipboard = new ClipboardJS('.btn', {text: function () {return 'to be or not to be';},});clipboard.on('success', function (e) {console.log(e);});clipboard.on('error', function (e) {console.log(e);});</script></body></html>
通过属性返回复印的内容:
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8" /><title>constructor-node</title><meta name="viewport" content="width=device-width, initial-scale=1" /></head><body><!-- 1. Define some markup --><div id="btn" data-clipboard-text="1"><span>Copy</span></div><!-- 2. Include library --><script src="../dist/clipboard.min.js"></script><!-- 3. Instantiate clipboard by passing a HTML element --><script>var btn = document.getElementById('btn');var clipboard = new ClipboardJS(btn);clipboard.on('success', function (e) {console.log(e);});clipboard.on('error', function (e) {console.log(e);});</script></body></html>
