jquery - Prevent Javascript from being executed twice -

-

i have script developing creates sliding button type effect. 5 div's situated next eachother each link. when 1 of divs clicked on associated content expanded , rest of div's closed.

the problem is, if user clicks div twice while loads or clicks div in rapid succession, cracks start show.

i wondering if possible allow query executed once , wait until completion rather queuing it.

here current code, if crap feel free comment on how better it... not best @ javascript/jquery :p

    function mnuclick(x){     //reset elements     if($('#'+x).width()!=369){         $('.menu .menu_graphic').fadeout(300);         $('.menu_left .menu_graphic').fadeout(300);         $('.menu_right .menu_graphic').fadeout(300);         $('.menu').animate({width: "76px"},500);         $('.menu_left').animate({width: "76px"},500);         $('.menu_right').animate({width: "76px"},500);     }         var elementid = '#' + x;          $(elementid).animate({             width: 369 + "px"         },500, function(){              $(elementid + ' .menu_graphic').fadein(300);         }); }

thanks in advance, chris.

you need "isrunning" flag. check before start. set when start sequence, clear when ends.
