jsf - 什么是 JSF、RichFaces 中的 LimitToList？它在 RichFaces 4.x 中被删除了吗？

Question

什么是limitToList在 JSF 中，RichFaces？它在 RichFaces 4.x 中被删除了吗？是 limitToList和 limitRender一样吗？

Answer 1

limitRender在 RichFaces 4.x 中是什么 limitToList适用于 RichFaces 3.x。

除了 limitReder是通过 render 实现的属性和 limitToList是通过 reRender 实现的属性

以下是来自 limitToList 的 RichFaces 引用指南 3.x 的解释.

"limitToList" attribute allows to dismiss the behavior of the "ajaxRendered" attribute. limitToList = "true" means to update only the area(s) that mentioned in the "reRender" attribute explicitly. All output panels with ajaxRendered="true" is ignored. An example is placed below:

...
<h:form>
    <h:inputText value="#{person.name}">
        <a4j:support event="onkeyup" reRender="test" limitToList="true"/>
    </h:inputText>
    <h:outputText value="#{person.name}" id="test"/>
</form>
...

以下是对 limitRender的解释来自 RichFaces 开发指南。

RichFaces Ajax-enabled components and Ajax behaviors with limitRender="true" specified will not cause components with ajaxRendered="true" to re-render, and only those components listed in the render attribute will be updated. This essentially overrides the ajaxRendered attribute in other components.
