感觉是你的双引号没有转义造成的，
试试：
<script> if(online[0]==0){ document.write("<a href=\"http://sighttp.qq.com/cgi-bin/check?sigkey=81a37f0b7cac68639bddfdb9b93a6c92bc211f3e3a4e683afbb31a079382dc9d\"; target=_blank; onclick=\"var tempSrc='http://sighttp.qq.com/wpa.js?rantime='+Math.random()+'&sigkey=81a37f0b7cac68639bddfdb9b93a6c92bc211f3e3a4e683afbb31a079382dc9d';var oldscript=document.getElementById('testJs');var newscript=document.createElement('script');newscript.setAttribute('type','text/javascript'); newscript.setAttribute('id', 'testJs');newscript.setAttribute('src',tempSrc);if(oldscript == null){document.body.appendChild(newscript);}else{oldscript.parentNode.replaceChild(newscript, oldscript);}return false;\"><img border=\"0\" SRC='http://xxxx/outline.jpg' alt=\"点击这里给我发消息\"></a>");}else{ document.write("<a href=\"http://sighttp.qq.com/cgi-bin/check?sigkey=81a37f0b7cac68639bddfdb9b93a6c92bc211f3e3a4e683afbb31a079382dc9d\"; target=_blank; onclick=\"var tempSrc='http://sighttp.qq.com/wpa.js?rantime='+Math.random()+'&sigkey=81a37f0b7cac68639bddfdb9b93a6c92bc211f3e3a4e683afbb31a079382dc9d';var oldscript=document.getElementById('testJs');var newscript=document.createElement('script');newscript.setAttribute('type','text/javascript'); newscript.setAttribute('id', 'testJs');newscript.setAttribute('src',tempSrc);if(oldscript == null){document.body.appendChild(newscript);}else{oldscript.parentNode.replaceChild(newscript, oldscript);}return false;\"><img border=\"0\" SRC='http://xxxx/online.jpg' alt=\"点击这里给我发消息\"></a>");} </script>
