文档一
<script language="text/javascript">
var xmlHttp
function showHint(str)
{
xmlHttp=GetXmlHttpObject()//创建xmlHttp实例对象的的函数被我省略了
var url="gethint.jsp";
url=url+"?q="+str;
url=url+"&sid="+Math.random();//1
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("GET",url,true);
xmlHttp.send(null);
}
function stateChanged()
{
if (xmlHttp.readyState==4)
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText;
}
}
</script>
</head>
<body>
<form>
First Name:<input type="text" id="txt1" onkeyup="showHint(this.value)" />
</form>
<p>Suggestions: <span id="txtHint"></span></p>
</body>
</html>

文档gethint.jsp
<%
response.expires=-1
dim a(5)
a(0)="Jack"
a(1)="Anna"
a(2)="Brittany"
a(3)="Cinderella"
a(4)="Diana"
a(5)="Eva"
q=ucase(request.querystring("q"))
if len(q)>0 then
hint=""
for i=0 to 5
if q=ucase(mid(a(i),1,len(q))) then
if hint="" then
hint=a(i)
else
hint=hint & " , " & a(i)
end if
end if
next
end if
if hint="" then
response.write("no suggestion")
else
response.write(hint)
end if
%>
上面是一个通过ajax进行异步通信，文档一中我省略了一些代码,所请求的页面gethint.jsp是用vbscript完成的，文档一中//1这一句是什么意思？？
