[removed] Scroll to nth row in a table?

Question

Using either pure Javascript or jQuery, how do I scroll the page so that the nth row in a table is centered on the page?

Some examples I\'ve seen that have this sort

Answer 1

Latest update (no-jquery for for modern browsers)

var rows = document.querySelectorAll('#tableid tr');

// line is zero-based
// line is the row number that you want to see into view after scroll    
rows[line].scrollIntoView({
    behavior: 'smooth',
    block: 'center'
});

Since you can use jQuery here it is..

var w = $(window);
var row = $('#tableid').find('tr').eq( line );

if (row.length){
    w.scrollTop( row.offset().top - (w.height()/2) );
}

If you want it to animate instead of just going there use

var w = $(window);
var row = $('#tableid').find('tr').eq( line );

if (row.length){
    $('html,body').animate({scrollTop: row.offset().top - (w.height()/2)}, 1000 );
}
