continue abc;
Response.Write ("eee");

I get:

Microsoft JScript compilation error '800a0402'
Label not found
/js.asp, line 8
continue abc;
------------^

I don't believe you can use a label, just the continue command (which looks
like it will accomplish the same thing). continue tells the loop to move to
the next iteration without executing the code that follows. In VBScript
you'd have to nest an if/else or select case. In JScript, if you want to
skip statements, you won't use continue, you'd have to use if ...

Try this instead:

<%@ Language=JScript %>
<%
var a=0;
while(a<20)
{
a++;
if (a==10) continue;
Response.Write ("eee");
}
%>

Thank you for your help!
But,I want use a statement in JScript,which like C language's goto;

<%@ Language=JScript %>
<%
var a=0,b=7;
while(a<20)
{
a++;
if (a==b)
continue abc;
}
Response.Write ("eee");
abc:
%>
I know this script is error.How can use a statement like C's goto?
Thank you

Like I said, I don't think you can use it the way you're trying (I assume
you want to put code under abc: so that you can skip the response.write line
but stay in the same iteration). Continue is used to move to the next
iteration; it is not a goto, and you cannot use it to move to different
lines of code within the same scope. Have you considered using IF like most
people would?
