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
<script type="text/javascript" src="prototype.js"></script>
创建层和显示查询结果的js代码
<script type="text/javascript">
//定义变量lastindex 表示为鼠标在查询结果上滑动所在位置，初始为-1
var lastindex=-1;
//定义变量flag 表示是否根据用户输入的关键字进行ajax查询,flase为允许查询 true为禁止查询
var flag=false;
//返回的查询结果生成的数组长度
var listlength=0;
//创建自定字符串，优化效率
function StringBuffer(){this.data=[];}
//赋值
StringBuffer.prototype.append=function(){this.data.push(arguments[0]);return this;}
//输出
StringBuffer.prototype.tostring=function(){return this.data.join("");}
//去掉字符串两边空格
String.prototype.Trim = function(){return this.replace(/(^s*)|(s*$)/g, "");}
//隐藏函数主要是隐藏显示的提示下拉层和iframe，关于iframe下面在说其作用
function hiddensearch()
{
$('rlist').style.display="none";
$('rFrame').style.display="none";
}
//显示函数主要是显示的提示下拉层和iframe 参数num,根据该参数控制要显示提示层和iframe的高度
function showsearch(num)
{
$('rlist').style.display='';
$('rFrame').style.display='';
//这里我定义每个返回查询结果的提示高度为20px,其中提示层总高度又加了num,是因为我在定义样式时使用了padding一个像素
$('rlist').style.height=num*20+num+'px';
//同样定位iframe的高度
$('rFrame').style.height=num*20+num+'px';
}
//返回文本输入框的坐标函数，参数element为要返回的对象,参数offset可选为offsetLeft|offsetTop 分别表示为该对象距离左窗口上角的绝对位置
//利用这个函数可以定位我们要显示的提示层位置，使提示层正确的显示在文本输入框下面
function getposition(element,offset)
{
    var c=0;
    while(element)
    {
        c+=element[offset];
        element=element.offsetParent
    }
    return c;
}
//创建提示层函数包括提示层和为了避免在文本输入框下面出现select下拉选框时我们的提示层不能再select之上的iframe
//可以理解为当文本输入框下有select下拉选框时从底向上依次为 select下拉选框-iframe-提示层
function createlist()
{
//创建提示层
var listDiv=document.createElement("div");
//提示层id
listDiv.id="rlist";
listDiv.style.zIndex="2";
listDiv.style.position="absolute";
listDiv.style.border="solid 1px #000000";
listDiv.style.backgroundColor="#FFFFFF";
listDiv.style.display="none";
listDiv.style.width=$('keyword').clientWidth+"px";
listDiv.style.left=getposition($('keyword'),'offsetLeft')+1.5+"px";
listDiv.style.top =(getposition($('keyword'),'offsetTop')+$('keyword').clientHeight +3)+"px";
