顶和踩JQ实现
样式如下：
js代码部分：<script><br />
$(function () {<br />
//鼠标滑向和离开投票按钮时，变换背景样式<br />
$("#dig_up").hover(function () {<br />
$(this).addClass("digup_on");<br />
}, function () {<br />
$(this).removeClass("digup_on");<br />
});<br />
$("#dig_down").hover(function () {<br />
$(this).addClass("digdown_on");<br />
}, function () {<br />
$(this).removeClass("digdown_on");<br />
});<br />
// 获得文章ID<br />
var aid = "{$article.art_id}";<br />
//初始化数据<br />
getdata("/votes/aid/" + aid);<br />
<br />
//单击“顶”时动作方法<br />
$("#dig_up").click(function () {<br />
//两种方法选其一<br />
//getdata("{:U('Index/votes',array('action'=>'like'))}",aid);<br />
getdata("/votes/action/like/aid/" + aid);<br />
});<br />
//单击“踩”时动作方法<br />
$("#dig_down").click(function () {<br />
//两种方法选其一<br />
//getdata("{:U('Index/votes',array('action'=>'unlike'))}",aid);<br />
getdata("/votes/action/unlike/aid/" + aid);<br />
});<br />
});<br />
function getdata(url, aid) {<br />
$.getJSON(url, {aid: aid}, function (data) {<br />
if (data.success == 1) {<br />
$("#num_up").html(data.like);<br />
$("#bar_up span").css("width", data.like_percent);<br />
$("#bar_up i").html(data.like_percent);<br />
$("#num_down").html(data.unlike);<br />
$("#bar_down span").css("width", data.unlike_percent);<br />
$("#bar_down i").html(data.unlike_percent);<br />
} else {<br />
$("#msg").html(data.msg).show().css({'opacity': 1, 'top': '40px'}).animate({<br />
top: '-50px',<br />
opacity: 0<br />
}, "slow");<br />
}<br />
});<br />
}<br />
