How to add a JavaScript listener to a PrimeFaces Ajax event
提问by dsafagasg14124
I want to listen pickList transfer event via javascript method,
我想通过javascript方法监听pickList传输事件，
Listener works well with java bean:
侦听器与 java bean 配合良好：
<p:pickList value="#{pickListBean.cities}" var="city"
itemLabel="#{city}" itemValue="#{city}">
<p:ajax event="transfer" listener="#{pickListBean.handleTransfer}" />
</p:pickList>
But that doesn't work:
但这不起作用：
listener="myJavaScriptMethod(event)"
Are there any way listening events like above?
有没有办法像上面那样监听事件？

listener is serverside, in client you can use oncomplete, onsuccess,..(your option):
侦听器是服务器端，在客户端，您可以使用 oncomplete、onsuccess、..（您的选项）：
<p:ajax event="transfer" oncomplete="js_function()" />
<p:ajax event="transfer" onstart="js_function()" />
...
