TOP     utility.addDelUrlP()

Add or delete a particular url parameter to the provided url-query (?x&y=2&z) string.

PARAMETERS

• s_urlq: The window.location.search. Assumed to be valid and provided. Must be either empty string (''), or start with a question mark ('?').
• b_pNeeded: Is the url parameter desired? If true, yes. If false, no.
• s_urlp: The url parameter that should ultimately exist or not exist, depending on the value of b_pNeeded, in the returned value.

RETURNS

• The url query string (either empty string [''], or a string starting with '?'), with s_urlp in or not in it, as appropriate. For example, if s_urlp needed but not currently existing, then s_urlp is added to s_urlq. If it's needed and already there, s_urlq is returned as is...
