save some byte in filter

[rformato]

Hi, I continue my search to save bytes in jQuery.

My current target is the filter function which refers multiple times to jQuery.expr[ m[1] ]

I stored this value in a var saving 17 bytes.

In the code there is also a resort call that moves the elements inside m to different indexes. However, it seems that the m[1] element remains at index 1.

This, even if dangerous in the long run (more resort functions can appear in the future moving the m[1] element), could bring us even more compression (saving 30 bytes).

This last optimization consists in deleting the second f assignment

f = jQuery.expr[ m[1] ];
if ( f._resort )
  m = f._resort( m );
f = jQuery.expr[ m[1] ];

The "secure" patch is attached.

This is old, there's nothing like this now.
