콘텐츠 편집 가능한 요소에서 캐럿 위치를 설정하는 방법은 무엇입니까?

function setCaret() {
    var el = document.getElementById("editable");
    var range = document.createRange();
    var sel = window.getSelection();

    // Set the start position of the range at the beginning of the fifth character of the third line
    range.setStart(el.childNodes[2], 5);

    // Collapse the range to the start point
    range.collapse(true);

    // Set the selection to start at the start position of the range
    sel.removeAllRanges();
    sel.addRange(range);
}
