Question

Silly question I think, but is there a way to use the “if” statement as a reusable function

    success: function(msg){
     if(msg=='o'){
        $j('#ok').show();
        $j(button).show();
        $j('#chk').hide();
        }
    else{
        $j('#ok').hide();
        $j('#chk').show();
        $j(button).hide();
        }

    }

I have a number of times when I want to call it and I would rather have a “smaller” weight.

This technique employs ‘closures’ to generate a function to provide as a success method:

function doStuffGenerator( button ){ 
  return function( msg ){ 
    if(msg=='o'){
        $j('#ok').show();
        $j(button).show();
        $j('#chk').hide();
    }
    else{
        $j('#ok').hide();
        $j('#chk').show();
        $j(button).hide();
    }
  };
}

...
jQuery.ajax({ 
   ...
   success: doStuffGenerator( button )
   ...
});
