Reset to default 6 +25Change "show" to "shown" when did you use bootstrap 3 or 4
$('#centralModalLg').on('shown.bs.modal', function() {
$( "#elementId" ).scrollTop(0);
});
check that Bootstrap 3 codepen example
check that Bootstrap 4 codepen example
$('#centralModalLg').on('shown.bs.modal', function() {
$('#elementId').scrollTop(0);
});
A Fiddle with your code.
EDIT: The issue is caused by the event listener, should be shown.bs.modal instead of show.bs.modal, updated the fiddle as well.
jQuery.scrollTop() could be conflicting if the event is started but not yet pleted as of Bootstrap's official documentation :
the infinitive (ex. show) is triggered at the start of an event, and its past participle form (ex. shown) is triggered on the pletion of an action.
try this:
$('#centralModalLg').on('show.bs.modal', function() {
setTimeout(function() {
var $elem = $('#scrollto') // add this ID to an element you want scroll to
var $container = $("#elementId")
$container.scrollTop(0) // edge case - reset scroll in case it is reopened
var t = $container.offset().top
$container.scrollTop($elem.position().top - t);
}, 500) // run after modal animation
});
It is based on this answer: https://stackoverflow./a/21179878/8164758
Here is working jsfiddle example: https://jsfiddle/954jnt2y/1/
