第一种
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
var body_element = document.getElementsByTagName('body')[0];
var selection = window.getSelection();
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
tag workaround
//otherwise the text inside "pre" loses all the line breaks!
if (selection.getRangeAt(0).commonAncestorContainer.nodeName == "PRE") {
newdiv.innerHTML = "" + newdiv.innerHTML + "";
}newdiv.innerHTML += "

- document.location.href + "'>"
- document.location.href + " © MySite.com";
selection.selectAllChildren(newdiv);
window.setTimeout(function () { body_element.removeChild(newdiv); },200);
});
