一个快速添加标签的小玩意，但在FF下不能用，望高手指点

初步判断是obj.style.backgroundcolor在ff下返回的是rgb(xxx,xxx,xxx)的缘故。偶是新手，代码很菜，高手勿笑啊

<meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>untitled document</title> <style type="text/css"> a.blue:link,a.blue:visited{ font-size: 12px; color: #69c; text-decoration: none; } a.blue:hover{ background: #69c; color: #fff; } </style> <input type="text" id="cc" style=" width: 300px;"><a href="/default/index/url?u=aHR0cHM6Ly93d3cuMTBxaWFud2FuLmNvbWphdmFzY3JpcHQ6dm9pZCgwKTs=" class="blue" onclick="finsert('cc',this);" target="_blank" rel="nofollow">关键字</a>　<a href="/default/index/url?u=aHR0cHM6Ly93d3cuMTBxaWFud2FuLmNvbWphdmFzY3JpcHQ6dm9pZCgwKTs=" class="blue" onclick="finsert('cc',this);" target="_blank" rel="nofollow">关键字2</a>　<a href="/default/index/url?u=aHR0cHM6Ly93d3cuMTBxaWFud2FuLmNvbWphdmFzY3JpcHQ6dm9pZCgwKTs=" class="blue" onclick="finsert('cc',this);" target="_blank" rel="nofollow">关键字3</a>
