[jQuery] Using Wildcards to find specific ID on a page

[jQuery] Using Wildcards to find specific ID on a page


Summary: I am new to JQuery. Is it possible to search for a element
by ID using a wildcard? Something like this where "*" indicates a
wildcard?
$('#*btnTest')
Background: I develop in ASP.Net. The button in question exist in a
user control, which when placed on a page modifies the generated input
id to something like "usercontrol1_btnTest". I could find new id and
modify the jquerry, but then the jquery code would only work for that
page. It seems a better design would be to write the script so it was
not dependant on the name of the page it lives on.
I am open to other suggestions as how to make this happen. I have not
looked at using classes vs IDs, allthough the elements in question are
already using classes. I have not considered multiple classes
though. However where I am really going though is binding to a
specifc (yes/no) radio button options (as genreated by a radio button
control), so a unique class should not apply to each radio button
option.
Thanks.
