JS:

  var grades = ["极差", "差", "一般", "好", "非常好"];

    function outStar(num, obj) {
        let nextAll = $(obj).nextAll(); //该节点后所有节点
        for (let i = 0; i < nextAll.length; i++) {
                $(nextAll[i]).text("☆")
        }
    }

    function setStar(nub, obj) {
        let prevAll = $(obj).prevAll(); //该节点后所有节点
        let nextAll = $(obj).nextAll(); //该节点后所有节点
        for (let i = 0; i < nextAll.length; i++) {
            $(nextAll[i]).text("☆")
        }
        for (var i = 0; i < prevAll.length; i++) {
            $(prevAll[i]).text("★")
        }
        $(obj).text("★")
        $(obj).parent().next().text(grades[nub]);
    }

    function clickStar(obj) {
        $(obj).text("★")
