jQuery：为无序列表编号

Posted 2021-02-24

Here’s a very simple script which adds numbers sequentially to an unordered list using jQuery

<script type="text/javascript"
src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.1.min.js">
</script>
 
<script type="text/javascript">
    $(function () {
        $('ul > li').each(function () {
            $(this).prepend("(" + 
                ($(this).index() + 1) + ") ");
        });
    })
</script>
