单个星级评分(纯JS):

<script type="text/javascript">
    window.onload = function () {
            var star = document.getElementById(a1).getElementsByTagName(a);

            var temp = 0;

            for (var i = 0, len = star.length; i < len; i++) {
                star[i].index = i;

                star[i].onmouseover = function () {
                    clear();
                    for (var j = 0; j < this.index + 1; j++) {
                        star[j].style.backgroundPosition = 0 0;
                    }
                }

                star[i].onmouseout = function () {
                    for (var j = 0; j < this.index + 1; j++) {
                        star[j].style.backgroundPosition = 0 -20px;
                    }
                    current(temp);
                }

                star[i].onclick = function () {
                    temp = this.index + 1;
                    document.getElementById(p1).innerHTML = temp +  颗星;
                    current(temp);
                }
        }
        //清除所有
        function clear() {
            for (var i = 0, len = star.length; i < len; i++) {
                star[i].style.backgroundPosition = 0 -20px;
            }
        }
        //显示当前第几颗星
        function current(temp) {
            for (var i = 0; i < temp; i++) {

            }
        }
