第一种
<script type="text/javascript"> document.body.oncopy = function(){ setTimeout( function (){ var text = clipboardData.getData("text"); if(text){ text = text + "/r/n本文来自: (www.VeVB.COm) 详细出处参考："+location.href; clipboardData.setData("text", text); } },100) } </script> 注意：这段代码必须复制到 body 区域里面才能生效，放到 head 区域内是不起作用的。
第二种
$("body").bind('copy', function (e) { if (typeof window.getSelection == "undefined") return; //IE8 or earlier... var body_element = document.getElementsByTagName('body')[0]; var selection = window.getSelection(); //if the selection is short let's not annoy our users if (("" + selection).length < 30) return; //create a div outside of the visible area //and fill it with the selected text var newdiv = document.createElement('div'); newdiv.style.position = 'absolute'; newdiv.style.left = '-99999px'; body_element.appendChild(newdiv); newdiv.appendChild(selection.getRangeAt(0).cloneContents()); //we need a <pre> tag workaround //otherwise the text inside "pre" loses all the line breaks! if (selection.getRangeAt(0).commonAncestorContainer.nodeName == "PRE") { newdiv.innerHTML = "<pre>" + newdiv.innerHTML + "</pre>"; } newdiv.innerHTML += "<br /><br />Read more at: <a href='" + document.location.href + "'>" + document.location.href + "</a> © MySite.com"; selection.selectAllChildren(newdiv); window.setTimeout(function () { body_element.removeChild(newdiv); }, 200);});总结
