  Javascript代码

  

复制代码 代码如下:

  var TB = function() {

  var T$ = function(id) { return document.getElementById(id) }

  var T$$ = function(r, t) { return (r || document).getElementsByTagName(t) }

  var Stars = function(cid, rid, hid, config) {

  var lis = T$$(T$(cid), 'li'), curA;

  for (var i = 0, len = lis.length; i < len; i++) {

  lis[i]._val = i;

  lis[i].onclick = function() {

  T$(rid).innerHTML = '<em>' + (T$(hid).value = T$$(this, 'a')[0].getAttribute('star:value')) + '分</em> - ' + config.info[this._val];

  curA = T$$(T$(cid), 'a')[T$(hid).value / config.step - 1];

  };

  lis[i].onmouseout = function() {

  curA && (curA.className += config.curcss);

  }

  lis[i].onmouseover = function() {

  curA && (curA.className = curA.className.replace(config.curcss, ''));

  }

  }

  };

  return {Stars: Stars}

  }().Stars('stars2', 'stars2-tips', 'stars2-input', {
