你没有提供具体需求没法给你写,不过可以提示你一下:
用JS调用是通过XMLHttpRequest这个对象来实现的,他负责封装浏览器端的请求然后传递给服务器端,服务器端处理完将返回的数据封装成XML格式,放在Response对象里发回浏览器端,浏览器就可以通过JS提供的方法来访问XML文档得到服务器端返回的数据。建议你去看看Ajax有关资料
这是JS代码,被保存在"clienthint.js"文件中
var xmlHttp
function showHint(str)
{
if (str.length > 0)
{
var url="gethint.asp?sid=" + Math.random() + "&q=" + str
xmlHttp=GetXmlHttpObject(stateChanged)
xmlHttp.open("GET", url , true)
xmlHttp.send(null)
}
else
{
document.getElementById("txtHint").innerHTML=""
}
}
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtHint").innerHTML=xmlHttp.responseText
}
