使用循环在 JSF 中创建命令按钮？

Question

for an example in an array there is

Edit --> #{testBean.edit}
Delete --> #{testBean.delete}
Copy --> #{testBean.copy}

is it possible to create commandbutton using loop or something

for(i=0;i<=array.length;i++)<br>
{
print '<h:commandbutton value="#{testBean.array.name}" action="#{testBean.array.action}" />'
}

so the output shld be like

<h:commandbutton value="Edit" action="#{testBean.edit}" />
<h:commandbutton value="Delete" action="#{testBean.delete}" />
<h:commandbutton value="Copy" action="#{testBean.copy}" />

Answer 1

That's only possible if you change the collection (map?) to look something like

Edit --> edit
Delete --> delete
Copy --> copy

Eg

Map<String, String> buttons = new LinkedHashMap<String, String>();
buttons.put("Edit", "edit");
buttons.put("Delete", "delete");
buttons.put("Copy", "copy");

You can then loop over it as follows:

<ui:repeat value="#{bean.buttons}" var="button">
    <h:commandButton value="#{button.key}" action="#{bean[button.value]}" />
</ui:repeat>

As an alternative, you can create the components programmatically from in the bean side.
