<%
var w;
w = String(Request.Cookies("name"));
var len = w.length;
Response.Write("w="+w+" len2="+len+"<br>");
%>
<%
var w;
w = String(Request.Cookies("name"));
var len = w.length;
Response.Write("w="+w+" len2="+len+"<br>");
%>

var w;
w = Request.Cookies("name").toString();
var len = w.length;

<%
var w;
w = Request.Cookies( "name ").toString();
var len = w.length;
Response.Write( "w= "+w+ " len2= "+len+ " <br> ");
%>
var w;
w = Request.Cookies( "name ").toString();
var len = w.length;
Response.Write( "w= "+w+ " len2= "+len+ " <br> ");

以下代码是ok的
<%
var w;
w = Request.Cookies("name");
w = "1234";
var len = w.length;
Response.Write("w="+w+" len2="+len+"<br>");
%>
结果
w=1234 len2=4
<%
var w;
w = Request.Cookies("name");
w = "1234";
var len = w.length;
Response.Write("w="+w+" len2="+len+"<br>");
%>
结果
w=1234 len2=4

w.length(); ？？？asp忘了
DoubleJiang 2007-11-21
不行，修改为
<%
var w;
w = Request.Cookies("name");
var len = w.length;
Response.Write("w="+w+" len2="+len+"<br>");
%>
结果
w=b1 len2=undefined
<%
var w;
w = Request.Cookies("name");
var len = w.length;
Response.Write("w="+w+" len2="+len+"<br>");
%>
结果
w=b1 len2=undefined
