2. $(function () { var id = 0;
3. $(“pre“).each(function () {
4. $(this).attr(“id“, ++id).attr(“ondblclick“, ‘copycode(‘ + id + ‘)‘);
5. })
6. }); function copycode(i) { const range = document.createRange();
7. range.selectNode(document.getElementsByTagName(‘pre‘)[i – 1]); const selection = window.getSelection(); if (selection.rangeCount > 0) selection.removeAllRanges();
8. selection.addRange(range); document.execCommand(‘copy‘);
9. alert(“复制成功“)
10. }</script>

第二种

1. <script>
2. function Toast(msg,duration){
3. duration=isNaN(duration)?3000:duration; var m = document.createElement(‘div‘);
4. m.innerHTML = msg;
5. m.style.cssText=“max–width:60%;min–width: 150px;padding:0 14px;height: 40px;color: rgb(255, 255, 255);line–height: 40px;text–align: center;border–radius: 4px;position: fixed;top: 50%;left: 50%;transform: translate(-50%, –50%);z–index: 999999;background: rgba(0, 0, 0,.7);font–size: 16px;“; document.body.appendChild(m);
6. setTimeout(function() { var d = 0.5;
7. m.style.webkitTransition = ‘-webkit–transform ‘ + d + ‘s ease–in, opacity ‘ + d + ‘s ease–in‘;
8. m.style.opacity = ‘0‘;
9. setTimeout(function() { document.body.removeChild(m) }, d * 1000);
