这是内部链接的 div 。 我试图用点替换上一个 < code@ lt; a> 中的逗号 。 "

此逗号来自列表的数字排序, 应该替换为点 。

问题是,所有存储在 links var 中的所有链接, 不知道如何获取最后一个链接, 然后替换它 。

有什么想法吗?

最佳回答

使用 String. replace

var links = $( a );

var $last = links.filter(":last");

$last.html( $last.html().replace(",", "."));

"http://jsbin.com/uxepap/5/edit" rel="no follow" >http://jsbin.com/uxepap/5/edit

问题回答
links.eq(-1).html(function(index, value) {
  return value.replace(/,s*$/, ".");
});
