在博客页首添加搜索功能

把博客园的搜索设置移植到了页面顶端，这样让博客的搜索功能更加醒目。
同时整合了“Adsense for Search” 以及“Add related keyword links”(添加相关关键字链接，起到搜索提示的功能）。
下面是我使用的代码：

<script language="JavaScript">
function SearchGoogle(key,evt,site)
        {
            if(evt.keyCode==13 || evt.keyCode==0 || evt.type =='click')
            {
                key.focus();
                var keystr = encodeURIComponent(key.value);
                url = "http://www.google.com/search?q=";
                url = url+keystr;
                url += "&client=pub-7558339387099421&forid=1&ie=UTF-8&oe=UTF-8&safe=active&cof=GALT%3A%23008000%3BGL%3A1%3BDIV%3A%23336699%3BVLC%3A663399%3BAH%3Acenter%3BBGC%3AFFFFFF%3BLBGC%3A336699%3BALC%3A0000FF%3BLC%3A0000FF%3BT%3A000000%3BGFNT%3A0000FF%3BGIMP%3A0000FF%3BFORID%3A1&hl=zh-CN&x=0&y=0&domains="+site+"&sitesearch="+site;
                window.location=url;
                return false;
            }
        }
</script>
