ul, li {margin: 0; padding: 0; border: 0;}
.shop-rating {
height: 25px;
overflow: hidden;
zoom: 1;
padding: 2px 0;

width: 60%;
z-index: 4;
}
.rating-level a.four-stars {
width: 80%;
z-index: 3;
}
.rating-level a.five-stars {

}
.rating-level .current-rating, .rating-level a:hover {background-position:0 -28px}
.rating-level a.one-star:hover,.rating-level a.two-stars:hover,.rating-level a.one-star.current-rating,.rating-level a.two-stars.current-rating{background-position:0 -116px;}
.rating-level .three-stars .current-rating,.rating-level .four-stars .current-rating,.rating-level .five-stars .current-rating{background-position:0 -28px;}
HTML結構
復制代碼 代碼如下:
<div class="shop-rating">
<span class="title">你對我人品的評價:</span>
<ul class="rating-level" id="stars2">
<li><a href="Javascript:void(0);" class="one-star" star:value="20">20</a></li>
<li><a href="Javascript:void(0);" class="two-stars" star:value="40">40</a></li>
<li><a href="Javascript:void(0);" class="three-stars" star:value="60">60</a></li>
<li><a href="Javascript:void(0);" class="four-stars" star:value="80">80</a></li>
<li><a href="Javascript:void(0);" class="five-stars" star:value="100">100</a></li>
</ul>
<span id="stars2-tips" class="result"></span>
<input type="hidden" id="stars2-input" name="b" value="" size="2" />
</div>
Javascript代碼
復制代碼 代碼如下:
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', {
'info' : ['人品極差', '人品不咋地', '人品一般吧', '人品不錯', '人品極好啊'],
'curcss': ' current-rating',
'step': 20
});
