On the browser page I'm on there is a "Log in" button that initializes a child window (i.e. window.open(...)). The page that actually loads is a
jsp from a totally different domain. It's this page that prompts for a username and password, the form's action goes to another page (which happens far too quickly to see which one). The validation is done there. I supply the path of the "success" page and wherever the validation occurs handles transferring here. I'm unable to pass in values to tack onto the URL (well... I could but they aren't handled). The initial browser page (one that has the button to initialize logging in) has the "validtextfield" field. When the "success" page gets hit I want to hide the log in button and display a message (along the lines of Welcome <user>!). On the success page (which is actually a CGI script written in Perl) I have an in-line javascript that tries to handle communication with the parent window (main browser page).
Going by what you wrote, are you saying that because the initial child's page has been left behind I have no access to the parent window? The main issue here is not passing values to the success page but rather having the success page modify/access the parent window after it has determined whether the login passed or failed. I need to dynamically change the parent page accordingly to the response I get from the external application doing the validation. Does that make sense? If not let me know if you have any questions to help clarify. Thanks for the response.
