更改dedecms的搜索框为多功能搜索

把　head.htm　的 <form>与</form>之间的代码，替换为以下代码：

 <form name=bf onSubmit="bottomForm();return false;">
   <script>
 function bottomForm(){
 var $=document.bf.key.value;
 if(document.bf.sto[0].checked)window.open("./plus/search.php?kwtype=0&keyword="+$,"a1");
 if(document.bf.sto[1].checked)window.open("?q1="+"&q6=www.5loveb.com","a2");
 if(document.bf.sto[2].checked)window.open("?hl=zh-CN&q="+"&as_sitesearch=www.5loveb.com","a3");
// if(document.bf.sto[3].checked)window.open("?id=1&search="+$,"a4");
// if(document.bf.sto[4].checked)window.open("?word="+$,"a5");
// if(document.bf.sto[5].checked)window.open("?kw="+"&submit=search","a6");
 return false}
 </script>  <div class="form">
