scroll event not firing on div inside scroll-able div

I wish did fix the issue. The scroll event handler should be on the outer div, the one that has the scrollbar:
code :
<div style="overflow:auto; height:200px" (scroll)="scrollHandler($event)">
  <div>Hello {{name}}</div>
  ...
</div>

(jQuery) Scroll event.. I want to scroll the document to the point specified if the user scroll the page

should help you out The scrollTop property only accepts an integer (not pixels). Omit the px and it should be fine.
code :
$(window).scroll(function() {
    $('body').get(0).scrollTop = 3000; // note that this does only work if body has overflow
    // if it hasn't, use window instead
});

help you fix your problem Please refer below sample html , What you need is to bind the event "scroll" with the #parent element.
code :
$("#parent").on("scroll",function(){
    alert("Event Triggered!");
});

Prevent .scroll event from firing every time I scroll in same direction unless done otherwise

it fixes the issue I've a jquery code that changes my css class when I scroll up/down the page. This solves my purpose but it's firing the event every time I scroll the page and I'm concerned that this may affect the website performance. , Just check if you already operated the class change
code :
if(_top < _cur_top && _direction !== "down")
{
    // [...]
}
else if(_top >= _cur_top && _direction !== "up")
{
    // [...]
}
$(function(){
var _top = $(window).scrollTop();
var _direction = "";
$(window).scroll(function(){
    var _cur_top = $(window).scrollTop();
    if(_top < _cur_top && _direction !== "down")
    {
        _direction = 'down';
        $("#my_div").removeClass("up").addClass("down");
    }
    else if(_top >= _cur_top && _direction !== "up")
    {
        _direction = 'up';
        $("#my_div").removeClass("down").addClass("up");
    }
    _top = _cur_top;
    console.log(_direction);
});
});

JQuery Scroll Event keeps firing when you scroll more

this one helps. Of course it keeps firing with every scroll - you haven't removed the scroll event handler, and if the user keeps scrolling down the if condition will continue to be true for subsequent scroll events. Note that the handler is also firing for every scroll before the user reaches that point of the page, it just doesn't do anything noticeable because of the if.
code :
$(window).on('scroll', function() {
    var y_scroll_pos = window.pageYOffset;
    var scroll_pos_test = 450;  // set to whatever you want it to be

    if(y_scroll_pos > scroll_pos_test) {
      $(window).off('scroll');  // <--- add this
      alert("hey you hit it");
    }
});
