JQuery: scrolling stops before reaching element -

-

i'm using jquery's scrolltop scroll specific element but, weirdly, scrolling stops before reaching element. can have codepen have made.

here's html:

<div id="events">     <div id="event-list">         <div class="content">             <h2>vendredi 17 octobre</h2>             <ul id="event-1" class="event-title">                 list items             </ul>             <h2>vendredi 21 octobre</h2>             <ul id="event-2" class="event-title">                 list-items             </ul>         </div>     </div>      <div id="event-details">         <div class="content">             <section id="event-1" class="details">                 stuff             </section>              <section id="event-2" class="details">                 stuff             </section>         </div>     </div> </div>

and jquery:

$(function(){   var thisoffset = $("#event-2").offset().top;   console.log(thisoffset)    $(".scroll").on("click", function(e){     console.log("scroll")      $("#event-details .content").animate({        scrolltop: thisoffset      }, 1000)      e.preventdefault();   }); });

any idea why , how solve issue? thank you!

you can use 1 time same id in html page. use event-2 2 times id, scrolls first one.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
