jQuery extend with key in variable

Question

I have this function to add key in a data with k="Toto"

 $Root = $("#" + n); $Root.data("TFO", $.extend({ k: v }, $Root.data("TFO")));

But when I see $Root.data("TFO") I get k instead of the value in k

How can I do it?

Answer 1

Try this:

 var obj = {};
 obj[ k ] = v; //<--------- VALUE of k will be used here & NOT k
 $Root = $("#" + n); 
 $Root.data("tfo", $.extend(obj, $Root.data("tfo")));
 //or $Root.data()['tfo'] = $.extend( obj, $Root.data('tfo') );
