使用ajax无刷新技术
ajax.htm
<script> function f(){ var req =new ActiveXObject("Microsoft.XMLHTTP"); req.open("GET","ajax.asp?t1="+t1.value, true); req.onreadystatechange = function(){ if (req.readyState == 4) { if (req.status == 200) { msg.innerText = req.responseXML.documentElement.tagName; } } } req.send(null); }</script>
1：显示”OK”; 其他字符:显示”Error”
<input id="t1" /> <input type="button" onclick="f();" />
ajax.asp
<!--r> Response.ContentType="text/xml"
if request.querystring("t1")="1" then
response.write("<ok/>")
else
response.write("<error/>")
end if
-->
传统asp无刷新技术
old.htm
<script> function f(){
document.getElementById("o").src="old.asp?t1=" mce_src="old.asp?t1="+t1.value }</script>
1：显示”OK”; 其他字符:显示”Error”
<input name="1" id="t1" /> <input type="button" onclick="f();" /><iframe src="old.asp" style="display: none" id="o"></iframe>
old.asp
<!--r> if request.querystring="" then response.end
end if
if request.querystring("t1")="1" then ss="OK"
-->
<script> parent.msg.innerText="<%=ss%>"</script>
