I am trying to create a terms and conditions page where I have 'I Agree' button which should be disabled when the user is at the top/middle of the page. When the user reaches the end of the page the button should be enabled. For that I want to have Hostlistner/Directive/event binding which will listen to scroll and get the position of the scroll and inform when it reaches at bottom and enable I agree button. Is there any other way of doing it? I am new to angular. Thanks in advance
my html
<div class="modal-body" #agreement>
<h6 class="inittext">You must scroll to the end of the terms and conditions And press "Agree"
to continue with your request.</h6>
