嘿所有我试图找到所有标签 data-required =＆＃34; true＆＃34; 以找到它下面的下一个范围并添加*到
$('[data-required="True"]').next("span").append(
"<i class='icon-asterisk' style='color: rgba(255, 46, 49, 1);'>*</i> "

示例文字估算费用应变为估算费用* ，但不是。
像这样做 .next（＆＃34; span＆＃34;）：
$('[data-required="True"]').next("span").append(...)
似乎没有产生我想要的东西。有什么帮助吗？
答案 0 :(得分：2)
next()无效，it targets only siblings，而您的span不是label的兄弟。
这将获得父（<td>），它紧跟在元素（下一个<td>），find所有<span>的子元素之后<td>，将匹配的集合简化为first元素，append a＆＃34; *＆＃34;它。
$('[data-required="True"]').each(function(){
$(this).parent().next().find('span').first().append('*');
});
你能否编辑标记？即在跨度中添加一个类？
