是否可以中止<f:ajax>用“return false”？</f:ajax>

Question

If you do this:

<h:commandButton action="..." onclick="return false" />

The action will not occur.

The same does not work for <f:ajax> , meaning this doesn't work:

<f:ajax event="click" onevent="return false" listener="#{mrBean.doSomething()}" >
    <h:commandLink value="A Link"  \>
</f:ajax>

Or more correctly, the ajax action runs and I get this error in the javascript console:

Uncaught SyntaxError: Unexpected token return
myfaces._impl.core._Runtime.singletonExtendClass.chainjsf.js.jsf:7491
chainjsf.js.jsf:7696
(anonymous function)file.jsf
onclick

Is there a way abort the <f:ajax> action through a javascript in a similar fashion to the h:commandbutton example?

Answer 1

I did this:

<f:ajax event="click" onevent="doTheRefreshingPart()" listener="#{mrBean.doSomething()}" >
    <h:commandLink value="A Link" onclick="return doTheConfirmationPart" \>
</f:ajax>

I moved the part that is confirmation dependent to the actual commandlink and left the part that takes part of refreshing the page in the <f:ajax> part
