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++) { star[i].style.backgroundPosition = '0 0'; } } }; </script>
