貌似要支持javascript的浏览器才行，ie9不行。。。。。
新浪：
javascript:(function(){window.open('http://v.t.sina.com.cn/share/share.php?title='+encodeURIComponent(document.title)+'&url='+encodeURIComponent(location.href)+'&source=bookmark','_blank','width=450,height=400');})()
腾讯：javascript:(function(){window.open('http://v.t.qq.com/share/share.php?title='+encodeURIComponent(document.title)+'&url='+encodeURIComponent(location.href)+'&source=bookmark','_blank','width=450,height=400');})()
其他的只要在“【】”中输入萎勃域名应该就可以：javascript:(function(){window.open('http://v.【】/share/share.php?title='+encodeURIComponent(document.title)+'&url='+encodeURIComponent(location.href)+'&source=bookmark','_blank','width=450,height=400');})()
