Get the position from div top from last elment in scrollable div with jQuery

How can i get the position from div top from the last elment in a scrollable div with jQuery? I have tried this but it doesnt work:

let bES = $(id).children().last().scrollTop()
console.log(bES)

Answer

You can use the .position() method to read its top property :

let bES = $('#content').children().last().position().top
console.log(bES)

div {
  height: 60px;
  overflow: scroll;
}

input {
  display: block;
}

<div id="content">
  <input value="123">
  <input value="456">
  <input value="789">
</div>
