单选全选框如何实现

// 全选
function quanxuan() {
    let quan = document.getElementById("全选名");
    let ge = document.getElementsByClassName("单选名")
    for (let i = 0; i < ge.length; i++) {
        if (quan.checked == false) {
            ge[i].checked = false;
        } else {
            ge[i].checked = true;
        }
    }
}

// 单选
function danxuan() {
    let quan = document.getElementById("全选名");
    let ge = document.getElementsByClassName("单选名")
    for (let i = 0; i < ge.length; i++) {
        if (ge[i].checked == false) {
            quan.checked = false;
            return;
        } else {
            quan.checked = true;
        }
    }
}
