h:commandbutton与h:commandlink [英] h:commandbutton vs h:commandlink

问题描述

我们正在使用JSF-2.1.7并以所有形式发布请求.我试图证明是使用<h:commandButton>还是<h:commandLink>.可以使用样式和jQuery控制<h:commandLink>(href <a/>)的外观.

We are using JSF-2.1.7 and in all our form post requests. I am trying to justify whether to use <h:commandButton> or <h:commandLink> . The appearance of <h:commandLink> (href <a/> ) can be controlled using style and jQuery.

推荐使用哪个<h:commandButton>或<h:commandLink>?有什么真正的优势吗?

Which is recommended <h:commandButton> or <h:commandLink>? Is there any real advantage?

推荐答案

除了生成的标记和外观之外，没有功能上的区别. <h:commandButton>生成HTML <input type="submit">元素，而<h:commandLink>生成使用JavaScript提交表单的HTML <a>元素.两者都将用于提交表格.其他样式与功能无关.

There is no functional difference apart from the generated markup and the appearance. The <h:commandButton> generates a HTML <input type="submit"> element and the <h:commandLink> generates a HTML <a> element which uses JavaScript to submit the form. Both are to be used to submit a form. Additional styling is irrelevant to the functionality.

如果需要提交按钮，请使用<h:commandButton>；如果需要提交链接，请使用<h:commandLink>.如果那样对您没有意义，那么我不知道.如果您不能决定使用哪一种，则只需选择在UI角度最有意义的一种即可.询问网页设计师是否不确定.

Use the <h:commandButton> if you need a submit button and use the <h:commandLink> if you need a submit link. If that doesn't make sense to you, then I don't know. If you can't decide which one to use, just choose the one which makes the most sense in UI perspective. Ask the web designer if you're unsure.

<h:commandLink>和<h:outputLink>之间的区别更有趣.在此处可以得到详细解答:何时应改为使用h:outputLink的h:commandLink?

The difference between <h:commandLink> and <h:outputLink> is by the way more interesting. This is been answered in detail here: When should I use h:outputLink instead of h:commandLink?
