I am currently working on implementing a web calendar module within an iframe on page-b. This module consists of 1 page with two sections. Upon entering zipcodes and house numbers, the inputs are hidden and the calendar is displayed. The technology used here is asp.net.
Furthermore, the user has requested an input widget for their homepage. To fulfill this request, I have created an html widget page that will be placed inside an iframe as well.
Now, my concern is how can I transmit the inputs from one iframe (on page-a) to another iframe on a different page (page-b).
Considering that I am using aspx language while the customer's CMS is based on PHP (probably Joomla), I came across suggestions advising to mention the target iframe in the form action like so:
<form id="kalenderForm" action="page-b.php" target="iframe_name" method="post">
However, it seems that I also need to include target="_top" to exit the initial iframe. Any tips or recommendations on this matter would be highly appreciated. Thank you in advance.
