IE 和 Chrome（开发工具）都没有显示任何错误，然后呢？

Question

$(".slides_container").append(liHtml) 语法正确吗？没有人（浏览器客户端）在抱怨。

Answer 1

我使用 W3C 验证器 根据 HTML5 文档类型检查您的标记（经过一些编辑）：

<!DOCTYPE html>
<html>
  <head>
     <title>asdf</title>
  </head>
  <body>
    <div class='slide'><a href='asdf' target='_blank' border='0'><img width='420' height='220'  src='asdf'/></a><div class='caption' style='bottom:0'><p>asdf</p></div></div>
  </body>
</html>

这会出现以下错误：

• 锚点没有边框属性。您的意思是将其样式设置为 吗？
• 图像应该有一个 alt 标签

所以是的，您在 liHtml 的标记无效，但很容易修复。
