JSF中的class和styleClass属性之间有什么区别? [英] What is the difference between class and styleClass attributes in JSF?

问题描述

我看到，在JSF中，大多数标准组件都映射到HTML标签，例如<h:commandButton/>，具有属性class和styleClass.但是，无论我使用哪一个，都在标记中都呈现为class属性.

I see, that in JSF most of the standard components that mapped to HTML tags, e.g. <h:commandButton/>, have attributes class and styleClass. But no matter, which one I use, both is rendered as class attributes in markup.

那么为什么有两个目的相同的属性?

So why there are two attributes with the same purpose?

推荐答案

JSF组件中根本没有class属性.

There is simply no class attribute in JSF components.

在文档中，属性为styleClass:

呈现此元素时要应用的CSS样式类的以空格分隔的列表.此值必须作为生成的标记的类"属性传递.

Space-separated list of CSS style class(es) to be applied when this element is rendered. This value must be passed through as the "class" attribute on generated markup.

styleClass只是在呈现的HTML中转换为class.

The styleClass is simply converted as class in the rendered HTML.
