javascript - 结合多个悬停功能

我对jQuery很陌生，我想弄清楚是否有更好的方法来编写下面编写的jQuery代码。

我想知道是否可以使代码更精简，而不是为基本上做同样事情的每个悬停效果编写函数。

HTML:

<form action="" method="post" class="rating-choice empty">
    <ul>
        <li class="one">
            <label><input type="radio" value="0.5" name="rating" id="rating-1" />0.5 stars</label>
        </li>
        <li class="two">
            <label><input type="radio" value="1" name="rating" id="rating-2" />1 star</label>
        </li>
        <li class="three">
            <label><input type="radio" value="1.5" name="rating" id="rating-3" />1.5 stars</label>
        </li>
        <li class="four">
            <label><input type="radio" value="2" name="rating" id="rating-4" />2 stars</label>
        </li>
        <li class="five">
            <label><input type="radio" value="2.5" name="rating" id="rating-5" />2.5 stars</label>
        </li>
        <li class="six">
            <label><input type="radio" value="3" name="rating" id="rating-6" />3 stars</label>
        </li>
        <li class="seven">
            <label><input type="radio" value="3.5" name="rating" id="rating-7" />3.5 stars</label>
        </li>
        <li class="eight">
            <label><input type="radio" value="4" name="rating" id="rating-8" />4 stars</label>
        </li>
        <li class="nine">
            <label><input type="radio" value="4.5" name="rating" id="rating-9" />4.5 stars</label>
        </li>
        <li class="ten">
            <label><input type="radio" value="5" name="rating" id="rating-10" />5 stars</label>
        </li>
    </ul>
</form>

最佳答案

只需将hover事件附加到li上，如下所示:

$(document).ready(function(){
    $('li').hover(
        function(){
            var classSuffix = $(this).find('input').attr('id').split('-')[1];
            $('.rating-choice').prevAll().addBack().addClass('rating-' + classSuffix);
            $('.rating-choice').nextAll().removeClass('empty');
        },
        function(){
            var classSuffix = $(this).find('input').attr('id').split('-')[1];
            $('.rating-choice').prevAll().addBack().removeClass('rating-' + classSuffix);
        }
    );
});
