JSF ui:repeat vs h:dataTable [英] JSF ui:repeat vs h:dataTable

问题描述

在问这个问题之前，我拜访了许多其他相关问题，并试图收集最多的信息.但是，到目前为止，我发现我发现ui:repeat和h:dataTable之间没有真正/主要的区别，并且每当我们可以使用h:dataTable时，我们也可以使用ui:repeat(有时其中一个是彼此之间没有什么复杂，但是最后我们得到了相同的结果.

Before asking this question, I visited many other related ones and tried to gather the maximum of information. But, what I found till now let me understand that there is no real/major difference between ui:repeat and h:dataTable, and that whenever we can use h:dataTable we can also use ui:repeat (sometimes one of them is a little complex than the other, but at the end we got same results).

那么，在所有用例中，唯一的选择就是使用h:dataTable吗?或相反(唯一选择是ui:repeat)?

So, is there any use cases where the only choice is to use h:dataTable? or the opposite (only choice is ui:repeat)?

推荐答案

在任何情况下，唯一的选择就是使用h:dataTable?

• 如果要使用 UIData 为基础的组件(UIRepeat中不存在其所有特殊属性).
• 如果要通过JSF组件呈现HTML <table>.
• 如果您希望能够自定义<table>渲染(例如PrimeFaces <p:dataTable>会进行排序，过滤，分组，折叠，延迟加载等).
• 如果您不使用Facelets作为查看技术.
• If you want to use an UIData-based component (with all of its special attributes absent in UIRepeat).
• If you want to render a HTML <table> by a JSF component.
• If you want to be able to customize the <table> rendering (like PrimeFaces <p:dataTable> does with sorting, filtering, grouping, folding, lazyloading, etc, etc).
• If you aren't using Facelets as view technology.

或相反(唯一选择是ui:repeat)?

• 如果您不希望以上任何内容，因此需要一个纯净的无标记迭代组件.
• 如果您希望能够在迭代过程中跳过每个 n 个项目(使用step属性).
• If you don't want any of above and thus need a pure markup-less iteration component.
• If you want to be able to skip every n items during iteration (using step attribute).
