How to set up form action

[TimAnderson]

I've been developing a web app on a single computer and have been using http://localhost:8080/myServlet in my form action field.

Now I'm trying to run my server on a remote machine and can get my web page to come up, but when I hit the Submit button, it tries to access the local host, not the host where the server resides. I'm sure that I can hard-code the name of the server instead of localhost, but what happens if the web app gets moved to a different server? I'd have to modify index.html to set the new name of the server.

How can I setup the action property such that it will access myServlet no matter the name of the server that it resides on?

You could do this with javascript. You could change the url (action) in the form tag or use javacript document.form1.submit();

You could figure out which location the code is running on using javascript location object.

var currentURL = window.location;
alert ( currentURL.host ); // Displays 'www.example.com:80'

As an alternative use relative paths (../page.htm, page1.html) instead of absolute paths (http://yourserver.domain/page.htm, http://yourserver.domain/folder/page1.html). Then you can change servers or domains to your hearts content without having to use javascript hacks.

That worked! Thanks!
