A link that does the login procedure for me automatically

is there a HTML or a java script code that will allow me to create a link on my page and this link will allow me to access a site (that requires my username and password) to be automatically logs me in and access the data.:o

or is there a way to enter the username and password to the URL that would help me not to login... :o

Nope. Can't do it with JavaScript.

Browsers have a "same domain" policy builtin, which means that JavaScript can only affect pages from the same domain as where the source came from.
