数据库表：复制内容到剪贴板
代码:

CREATE TABLE `xqbar`.`suggest` (
`id` INT NOT NULL AUTO_INCREMENT ,
`title` VARCHAR( 100 ) NOT NULL ,
`hits` INT NOT NULL DEFAULT 0,
PRIMARY KEY ( `id` )
) ENGINE = InnoDB

insert into suggest(title,hits)values(xqbar.com,100);
insert into suggest(title,hits)values(www.xqbar.com,410);
insert into suggest(title,hits)values(http://xqbar.com,700);
insert into suggest(title,hits)values(mail:xqbar.com,200);
insert into suggest(title,hits)values(ftp:xqbar.com,100);
insert into suggest(title,hits)values(http://www.xqbar.com,70)search.php
(关于php我也是接触不久，下面的php如果罗嗦还望高手指点)
返回的信息字符串要为 xxx1|xxx2$200|100 前后对应复制内容到剪贴板
代码:

if($_GET["action"]!=){
   #获取用户输入的关键字
   $keyword=$_GET["keyword"];
   #过滤关键字
   $keyword=str_replace("[","[[]",$keyword);
   $keyword=str_replace("&","[&]",$keyword);
   $keyword=str_replace("%","[%]",$keyword);
   $keyword=str_replace("^","[^]",$keyword);
   #链接数据库
   $conn=mysql_connect("localhost","xqbar","xqbaradmin");
   #选择数据库
   @mysql_select_db("xqbar") or die(sorry);
   mysql_query(set names utf-8);
   #查询语句
   $sql="select title,hits from suggest where title like %".$keyword."% order by hits desc limit 10";
   $result=mysql_query($sql);
   #循环得到查询结果，返回字符串
   #格式为结果1|结果2$结果1点击次数|结果2点击次数
   if($result){
   $i=1;$title=;$hits=;
   while($row=mysql_fetch_array($result,MYSQL_BOTH))
   {
     $title=$title.$row[title];
   $hits=$hits.$row[hits];
   if($i {
   $title=$title."|";
   $hits=$hits."|";
}
$i++;
    }
   }
   mysql_close();
}
?>
js代码复制内容到剪贴板
代码:

引入prototye.js有朋友说这个库太大，或者把，不习惯的朋友可以使用jquery.js框架或者直接创建ajax对象，这个我就不想说了，这里直接引用prototye.js框架

创建层和显示查询结果的js代码

var listFrame=document.createElement("iframe");
listFrame.id="rFrame";
listFrame.style.zIndex="1";
listFrame.style.position="absolute";
listFrame.style.border="0";
listFrame.style.display="none";
listFrame.style.width=$(keyword).clientWidth+"px";
listFrame.style.left=getposition($(keyword),offsetLeft)+1+"px";
listFrame.style.top =(getposition($(keyword),offsetTop)+$(keyword).clientHeight +3)+"px";
document.body.appendChild(listDiv);
document.body.appendChild(listFrame);
}
function setstyle(element,classname)
{
switch (classname)
    {
     case m:
       element.style.fontSize="12px";
    element.style.fontFamily="arial,sans-serif";
    element.style.backgroundColor="#3366cc";
    element.style.color="black";
    element.style.width=$(keyword).clientWidth-2+"px";
    element.style.height="20px";
          element.style.padding="1px 0px 0px 2px";
          if(element.displaySpan)element.displaySpan.style.color="white"
    break;
     case d:
       element.style.fontSize="12px";
    element.style.fontFamily="arial,sans-serif";
    element.style.backgroundColor="white";
    element.style.color="black";
    element.style.width=$(keyword).clientWidth-2+"px";
    element.style.height="20px";
          element.style.padding="1px 0px 0px 2px";
          if(element.displaySpan)element.displaySpan.style.color="green"
    break;
case t:
       element.style.width="80%";
    if(window.navigator.userAgent.toLowerCase().indexOf("firefox")!=-1)element.style.cssFloat="left";
    else element.style.styleFloat="left";
    element.style.whiteSpace="nowrap";
    element.style.overflow="hidden";
    element.style.textOverflow="ellipsis";
    element.style.fontSize="12px";
    element.style.textAlign="left";
    break;
case h:
       element.style.width="20%";
    if(window.navigator.userAgent.toLowerCase().indexOf("firefox")!=-1)element.style.cssFloat="right";
