[jQuery] How to make it remove class show, and add class hide.

[jQuery] How to make it remove class show, and add class hide.


Okay, so I'm working on this site, currently I have this jquery code:
     $("a.show").click(function(event){
        $("a.show[id="+this.id+"]").removeClass("show")
        $("a[id="+this.id+"]").addClass("hide")
        $("div[title!="+this.id+"][class=news]").hide(500)
        $("div[title="+this.id+"][class=news]").show(500)
        event.preventDefault();
     });
it doesn't seem to remove the show class, and add the hide class.
