RichFaces复选框树 [英] RichFaces checkbox tree

问题描述

我正在实现RichFaces复选框树，但是有一个问题...当用户选择根节点时，我需要将所有子节点标记为已选中...

I'm implementing RichFaces checkbox tree, and I've got a problem... I need to mark all the child nodes as selected when user selects root node...

我想应该使用一些当用户选择根节点时调用的javascript函数来完成它.

I guees it should be done using some javascript function called when users selects root node...

任何想法?

推荐答案

花了很多时间使用javascript之后，我决定转到服务器端. 因此，要实现上述功能，树节点将在每次单击时发送ajax请求，然后服务器端对所有子节点执行选择或取消选择，并在请求处理完成后重新呈现树组件.以下代码演示了单节点内容:

After spending a lot of time with javascript, I decided to move to server side. So, to implement the above feature tree nodes are sending ajax requests on each click, then server-side performs selection or deselection of all the child nodes, and after request processing is finished tree component gets rerendered. The following code demonstrates single node content:

<rich:tree id="tree" ...
<rich:treeNode ...
    <h:selectBooleanCheckbox value="#{_node.selected}">
           <a4j:support event="onclick" action="#{_node.select(_node.selected)}" reRender="tree">
           </a4j:support>
    </h:selectBooleanCheckbox>
</rich:treeNode>
</rich:tree>

_node.select(_node.selected)在服务器端完成所有工作的地方.

Where _node.select(_node.selected) does all the job on server side.
