JQ “顶”和“踩”代码分享

废话不多说请看代码
js代码部分：


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

HTML代码部分：

具体CSS样式根据自己的实际情况调整吧

<div class="digg">
        <div id="dig_up" class="digup">
            <span id="num_up">133</span>
            <p>写的好，我很赞！</p>
            <div id="bar_up" class="bar"><span style="width:68%"></span><i>68%</i></div>
        </div>
        <div id="dig_down" class="digdown">
            <span id="num_down">42</span>
            <p>太差劲了！</p>
              <div id="bar_down" class="bar"><span style="width:32%"></span><i>32%</i></div>
        </div>
        <div id="msg"></div>
</div>
