Ajax replace instead of append

you could empty the element before you append

$("#results").empty().append(myHtml);

or use the html method

$("#results").html(myHtml)

Just change

$('#results').append(myHtml);

to

$('#results').html(myHtml);

OK, last entry 2009, but if the problem still exist:

let oldElement = $('#results')
let content = '<div id="#results>9000+</div>'
oldElement = oldElement.replaceWith(content)
let newElement = $('#results')
