[jQuery] Combining selectors

[nguyenq]

I need help in this compound selector problem. I have the following
jQuery statements, which are working:

    $("[EMAIL PROTECTED]'button']").addClass("button");
    $("[EMAIL PROTECTED]'submit']").addClass("button");
    $("[EMAIL PROTECTED]'reset']").addClass("button");

I want to combine them into a single statement, such as:

    $("[EMAIL PROTECTED]'button' or @type='submit' or
@type='reset']").addClass("button");

or

    $("[EMAIL PROTECTED]'button'] or [EMAIL PROTECTED]'submit'] or
[EMAIL PROTECTED]'reset']").addClass("button");

similar to the Boolean OR that XPATH expresssion allows, but it does
not work. What is the proper syntax, if the combining is possible?
