I have a search page here (TinyURL used to avoid google indexing):
By default the form action is this:
<form action="residential?frame=RESI&base=frames" method="post" name="byCity" id="byCity">
Under Step 2, I have the following form action onClick event.
<input type="radio" name="proptype" id="RESI" value="RESI" checked="checked" onClick="this.form.action='residential?frame=RESI&base=frames';" />
This works great EXCEPT when the user performs a search and then click the Back button in their browser to return to the search page.
When they do this, the form shows the Radio select in Step 2 is still selected but in reality it defaults to the default form action in Firefox. I assume its the same for other browsers.
Please provide a sample to try.
