[jQuery] Function call

Hi,

I wrote some lines to make an element fade in & out when HOVER another
text
this is my script:

$(sw1).hover(function () {
            if ($(slide_img).attr("src")!="images/1.jpg"){
               $(slide_img).fadeOut(200,function() {
                   $(slide_img).attr({src:"images/1.jpg"});
                   $(slide_img).fadeIn(200);
                   }
                   );}
            },function(event){  /* NOTHING HERE */ }
            );


I want to define a function named "slide" then call it when HOVER like
this:

$(sw1).hover(slide(),function(event){  /* NOTHING HERE */ } );


what should i write ???
