<input type="text" id="url" readonly class="form-control" name="url" placeholder="Email to:" value="<?= $sharelink ?>">
<button ?onClick="url.select();document.execCommand(‘Copy‘);alert(‘复制成功‘)" class="btn btn-primary btn-block"><b>复制链接</b></a>
2、引入js插件clipboard.js
<!-- 1. Define some markup -->
<div>hello</div>
<button class="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>
