f：ajax渲染接受哪些值

Question

In JSF I can update components with ajax:

<h:commandButton ...>
    <f:ajax render="@form" />
</h:commandButton>

I found some of these values in the web: @form @this @parent @none @region @all .

Is there a complete list of the standard values which come with <f:ajax> ? And do these values have a special name which I could lookup?

Answer 1

Just look in <f:ajax> tag documentation .

render

Evaluates to Collection<String> . The clientIds of components that will participate in the "render" portion of the Request Processing Lifecycle. If a literal is specified the identifiers must be space delimited. Any of the keywords " @this ", " @form ", " @all ", " @none " may be specified in the identifier list. If not specified, the default value of " @none " is assumed. For example, @this clientIdOne clientIdTwo .

The others you mentioned ( @region and @parent ) are recognizable as from PrimeFaces <p:ajax> . So if you were actually facing problems while trying that on <f:ajax> , you should now understand why.
