$ ("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 ();

 ');
 newdiv.style.position = ' absolute ';
 Newdiv.style.left = ' -99999px ';
 Body_element.appendchild (NEWDIV);
 
 Newdiv.appendchild (selection.getrangeat (0). Clonecontents ());

 newdiv.innerhtml + "</pre>"; } newdiv.innerhtml + + <br/><br/>read more at: <a href= ' "+ document.location.href +" ' > "+ docum Ent.locatioN.href + "</a>©mysite.com";
 Selection.selectallchildren (NEWDIV);
Window.settimeout (function () {body_element.removechild (newdiv);}, 200); });
