javascript - Hide one div, unhide another div, scroll to the new unhidden div -


i have function closegeneralhelp takes 1 parameter: idtag. function supposed following:

a) slideup "help" div, b) slidedown set of divs , c) scroll, jump, or otherwise go specific (but dynamically determined) other div of set of divs exposed via slidedown.

i have 2 classes of divs ("divstoshow" , "divtohide"). "divstoshow" has few other divs contained in , each of divs has unique id (this idtag is).

parts (a) , (b) work fine. scrolling specific (but dynamically determined) div seems fail no matter try. here code. each /* */ comment block represents separate, failed (and flailing) attempt @ making work.

any on getting (c) work? javascript / jquery infant. reasonably related advice / pointers appreciated.

function closegeneralhelp(idtag){     $(".divstoshow").slidedown("slow");     $(".divtohide").slideup("slow");     /* var divid = document.getelementbyid(idtag);     divid.style.display = 'block';     divid.scrollintoview(true);  */     /*  document.getelementbyid(idtag).scrollintoview();*/     /*  $(window).scrollto(idtag,800,{queue:true});*/     /* window.location.hash = idtag;*/     /* window.settimeout(function() {window.scroll(0, findpos(idtag));}, 5);*/ }

thank you!

you need callback function, in case after slidedown done:

$(".divtohide").slideup("slow"); $(".divstoshow").slidedown("slow", function(){     var $showndiv = $(this);     // callback of slidedown, after done, perform this:     $('html,body').scrolltop( $showndiv.scrolltop() );      // or animated:     $('html,body').animate({scrolltop: $showndiv.scrolltop()}, 1000); // in ms      // or more native js     document.getelementbyid( $(showndiv)[0].id ).scro‌​‌​llintoview(); });

if have old jquery , cant upgrade, might want discard $("#someelement").scrolltop() in favor of $('#someelement').offset().top
