How do i set the active tab in Primefaces tabView?
提问by Horacio González
I have a menubar in which two items on a submenu, both calling the same page:
我有一个菜单栏，其中子菜单上的两个项目都调用同一个页面：
<p:menubar autoSubmenuDisplay="true">
<p:submenu label="Perfil">
<p:menuitem value="Editar" url="perfil.xhtml" />
<p:menuitem value="Ver" url="perfil.xhtml" />
</p:submenu>
</p:menubar>
In that page i have a tabview with two tabs:
在该页面中，我有一个带有两个选项卡的 tabview：
<p:tabView dynamic="true">
<p:tab id="ver" title="Ver perfil">
<ui:include src="verPerfil.xhtml" />
</p:tab>
<p:tab id="editar" title="Editar perfil">
<ui:include src="editarPerfil.xhtml" />
</p:tab>
</p:tabView>
How can i set the active tab, so each menuitem activate the corresponding tab?

If you want to do this.You can't use the urlin the p:menuitembecause we must call a method to changing the tabindex beforeskipping to the prefil.xhtmlpage. If you use the url, the method will be invoked after we skip to the prefil.xhtmlpage .
如果你想这样做。你不能使用urlin ，p:menuitem因为我们必须在跳转到prefil.xhtml页面之前调用一个方法来更改 tabindex 。如果使用url，则跳转到prefil.xhtml页面后会调用该方法。
First, you can use the action field of the p:menuitem, the method returns the address you want to skip to:
首先，您可以使用 的操作字段p:menuitem，该方法返回您要跳转到的地址：
<p:menubar autoSubmenuDisplay="true">
<p:submenu label="Perfil">
<p:menuitem value="Editar" action="#{some.editar}" ajax="false"/>
<p:menuitem value="Ver" action="#{some.ver}" ajax="false" />
</p:submenu>
</p:menubar>
These two method do something to change the tabindex like this:
这两种方法可以像这样更改 tabindex：
public String editar() {
tabindex = 0;
return "verPerfil";
}
public String ver() {
tabindex = 1;
return "verPerfil";
}
Then the p:tabViewhas an attribute named activeIndex. It is the index of the active tab, its default value is 0. So you can do as follows:
然后p:tabView有一个名为 的属性activeIndex。它是活动选项卡的索引，其默认值为0。所以你可以这样做：
<p:tabView dynamic="true" activeIndex="#{some.tabindex}" >
<p:tab id="ver" title="Ver perfil">
<ui:include src="verPerfil.xhtml" />
</p:tab>
<p:tab id="editar" title="Editar perfil">
<ui:include src="editarPerfil.xhtml" />
</p:tab>
</p:tabView>
Then each menuitem will activate the corresponding tab.
然后每个菜单项将激活相应的选项卡。
