php - Php echo功能不适用于联系表单上的ajax
问题描述
最近我一直在尝试制作一个带有recaptcha 支持的html 联系表格,在php 上使用echo 来显示失败和成功消息,问题是我不知道为什么它没有与css 一起出现。但是当我<p class="alert alert-warning">Please check the the captcha form.</p>
在主网站上使用代码时它可以工作。

解决方案
因为在某处,您的 ajax 代码可能会像这样插入 HTML:
$('.ajax-response').text(result);
什么时候应该
$('.ajax-response').html(result);
