jQuery的animate scrolltop（）不在IE10中向下滚动

Question

When I apply this code and test this in Internet Explorer and FireFox, on click, the page does not scroll down with the toggle function, but it does scroll back up after closing the overlay. This works fine in Google Chrome, but not in IE 10 or Firefox. Please help. :)

  $(document).ready(function(){


 $(".PlaceHolders").click(function(e){

e.preventDefault();
$(".overlay").slideToggle(2000, function(){

  $("#url_placeholder").text($(this).is(':visible') ? "Close Components" : "View Available Components");
});
   $('html','body').animate({scrollTop: $(".PlaceHolders").offset().top}, 2000);
 });

Answer 1

It's just your selector. See http://codepen.io/anon/pen/MYNZzW

   $('html,body').animate({scrollTop: $(".PlaceHolders").offset().top}, 2000);

Answer 2

hope this is what you had wanted. Here's a working fiddle, tested in chrome and ie10,

$(document).ready(function(){

 $(".PlaceHolders").click(function(e){

$(".overlay").slideToggle("slow", function() {

 setTimeout(function(){
   $("#url_placeholder").text($(this).parent(".overlay").is(':visible') ? "Close Components" : "View Available Components");
  },500);
  });

  $("html, body").animate({ scrollTop: $("#url_placeholder").offset().top }, 1000);

e.preventDefault();
});

});
