If you put it in a form with a 'GET' method, it will do that without javascript. 
 

<pre><code class="code-1 nolinks" id="code-20-39744127-1">&lt;form action=&quot;mypage.asp&quot; method=&quot;get&quot; &gt;
&lt;label&gt;Go To party&lt;/label&gt;&lt;br /&gt;
&lt;input type=&quot;radio&quot; name=&quot;party&quot; id=&quot;rsvpyes&quot; value=&quot;yes&quot; /&gt; YES&lt;br /&gt;
&lt;input type=&quot;radio&quot; name=&quot;party&quot; id=&quot;rsvpno&quot; value=&quot;no&quot; /&gt; NO&lt;br /&gt;
&lt;input type=&quot;submit&quot; value=&quot;Submit&quot; /&gt;
</code></pre>

Did you want to click the link? or the radio?

As Dave has said why not use a form but with jquery

Dave GET won't work in this scenario. 
Scott and Padas, 
Very close to what I need but I should have been more clear with my question. My apologies, so I will increase points. 
 
My form POST but redirects to &quot;thankyoupage.asp&quot; based upon a value in a hidden input. I need to add/append &quot;yes&quot; or &quot;no&quot; to the end of &quot;thankyoupage.asp?party=&quot; so I can display the correct message dependent on whether they can attend or not attend party. 
 

<pre><code class="code-1 nolinks" id="code-20-39744199-1">&lt;form action=&quot;somepage.asp&quot; method=&quot;post&quot; name=&quot;form&quot; &gt;
&lt;input type=&quot;radio&quot; name=&quot;party&quot; id=&quot;rsvpyes&quot; value=&quot;yes&quot; /&gt; YES&lt;br /&gt;
&lt;input type=&quot;radio&quot; name=&quot;party&quot; id=&quot;rsvpno&quot; value=&quot;no&quot; /&gt; NO&lt;br /&gt;

&lt;button name=&quot;Submit&quot; type=&quot;submit&quot; value=&quot;Submit&quot; /&gt;RSVP&lt;/button&gt;

&lt;input type=&quot;hidden&quot; name=&quot;confirm page&quot; value=&quot;thankyoupage.asp?party=&quot;&gt;
&lt;/form&gt;
</code></pre>
 
Again, sorry for not being clearer.
</div>

<div>
when posting your page to somepage.asp, the script(somepage.asp) know if party is &lt;&lt;&nbsp;yes &gt;&gt;&nbsp;or &lt;&lt;&nbsp;no &gt;&gt;&nbsp; 
so why do you need an hidden field ? 
just concatenate the party query string value to your redirect string : 
 

<pre><code class="code-1 nolinks" id="code-20-39744212-1">Response.Redirect &quot;http://www.w3schools.com?party=&quot; &amp; Request.QueryString(&quot;party&quot;)
%&gt;
</code></pre>
</div>

<div>
There really is no need to use js or jquery on this page. &nbsp;The user selects yes or no then clicks the submit button. &nbsp;Then on the somepage.asp you would use 
 

<pre><code class="code-10 nolinks" id="code-20-39744223-1">&lt;%
party=&quot;no&quot;
if request.form(&quot;party&quot;)&lt;&gt;&quot;&quot; then
 if request.form(&quot;party&quot;)=&quot;yes&quot; then
 party=&quot;yes&quot;
end if
' later in the page

if party=&quot;yes&quot; then
 response.write &quot;Thank you for coming to my party&quot;
 else
 response.write &quot;I am sorry you can not come to my party&quot;
end if
%&gt;
</code></pre>
</div>

<div>
There you go, @swaggerking , three almost identical suggestions in a row as soon as we knew enough about what you were trying to do.
</div>

<div>
I hear you guys loud and clear and I agree with you 100%. Unfortunately I don't have access to &quot;somepage.asp&quot;. Somepage.asp is actually an internal form processing script. Internally we use this to process any inet form and redirect to any page using the hidden input &quot;confirm page&quot;. 
 
GaryC123, 

<pre><code class="code-1 nolinks" id="code-20-39744249-1">&lt;script&gt;
$(&quot;[name=form]&quot;).submit(function(){
 $(&quot;[name='confirm page']&quot;).val($(this).val() + $(&quot;:radio[name=party]:checked&quot;).val())
})
&lt;/script&gt;
</code></pre>
 
This only adds the value &quot;yes&quot; or &quot;no&quot; to the hidden 
example: 
&lt;input type=&quot;hidden&quot; name=&quot;confirmpage&quot; value=&quot;yes&quot;&gt; 
or 
&lt;input type=&quot;hidden&quot; name=&quot;confirmpage&quot; value=&quot;no&quot;&gt; 
 
I'd prefer: 
&lt;input type=&quot;hidden&quot; name=&quot;confirmpage&quot; value=&quot;thankyoupage.asp?party=yes&quot;&gt; 
or 
&lt;input type=&quot;hidden&quot; name=&quot;confirmpage&quot; value=&quot;thankyoupage.asp?party=no&quot;&gt;
</div>

<div>
Too late for me to test this now but if it is only setting the value to yes/no then change the script to 
 

<pre><code class="code-1 nolinks" id="code-20-39744302-1">&lt;script&gt;
$(&quot;[name=form]&quot;).submit(function(){
 $(&quot;[name='confirm page']&quot;).val($(&quot;[name='confirm page']&quot;).val + $(&quot;:radio[name=party]:checked&quot;).val())
})
&lt;/script&gt; 
</code></pre>
 
edit 
I see why now 
 
Still confused as to the logic behind this.
</div>

<div>
I got working with your suggestions. Much appreciation.

Javascript add input radio value to a parameter of a query string

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.

JavaScript

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

jQuery

Active Server Pages (ASP) is Microsoft’s first server-side engine for dynamic web pages. ASP’s support of the Component Object Model (COM) enables it to access and use compiled libraries such as DLLs. It has been superseded by ASP.NET, but will be supported by Internet Information Services (IIS) through at least 2022.
