Hi,
I may be wrong on understanding your question or need, but it sounds
like something I came across as well and wrote a plug-in solution.
Background:
The bottom line is the jQuery AJAX calls (.get, .load, etc) will use
an encoded url request and it issues ampersand (&) delimited key=value
(or name=value) pairs. lets call them NV pairs. The final request is:
url?parameters_in_nvpairs_format
example
/someprogram?p1=v1&p2=v2
However, that is not what you pass for parameters for the
optional .get(,parameter) variable. It only access an JSON formatted
object or array.
WRONG: --> .get(url, "p1=v1&p2=v2");
RIGHT--> .get(url, {p1:"v1", p2:"v2"})';
If you pass NVpairs, believe it or not, jQuery will see the strng as
an array of characters and send a pair for each character in the
string using the index of the string as the name or key:
0=p&1=1&2=%3D&3=v&4=1&5=%26&6=p&7=2&8=%3D&9=v&10=2
Solution:
I found this non support for passing a natural stirng of nvpairs to
be a "obstrusive" design so I created a override plug-in for the base
method $.param() which handles this transformation.
(function($) {
var _inherit = $.param;
if ($.fn.jquery && $.fn.jquery <= "1.1.3.1") {
$.param = function(a) {
return (a.constructor == String)?a:_inherit(a);
};
}
})(jQuery);
This will allow you to send a string of nvpairs, an JSON object or
array.
Note, the (a.constructor == String) line. Maybe that is all you
needed? To detect the type of variable?
Not sure if this applies to you, but I hope it helps.
