Using jquery ajax to call a jsf managed bean method (an AjaxBehaviorEvent listener handler)
提问by Bardelman
i would like to know if there is a way to fire a jsf managed bean method (with an AjaxBehaviorEvent type parameter: the same triggered when using f:ajax) directly by using a jquery ajax server request.By the way , i m a jsf developper and i didn't find an example about using jquery ajax with Java EE as a server-side framework, all examples i found were with php..so i wish to get a complete example about doing that. i think the other workaround maybe is to make a commandLink being submitted with jquery on the client side and passing parameters through that call but i prefer the former solution and i wish it work.
我想知道是否有办法直接通过使用 jquery ajax 服务器请求来触发 jsf 托管 bean 方法（使用 AjaxBehaviorEvent 类型参数：使用 f:ajax 时触发相同）。顺便说一句，ima jsf 开发人员和我没有找到关于将 jquery ajax 与 Java EE 一起用作服务器端框架的示例，我找到的所有示例都使用 php..所以我希望得到一个关于这样做的完整示例。我认为另一种解决方法可能是在客户端使用 jquery 提交 commandLink 并通过该调用传递参数，但我更喜欢前一种解决方案，我希望它起作用。
Thanks very much for help !
非常感谢您的帮助！

Here you go:
干得好：
<script type="text/javascript">
doAwesomeness();
</script>
In your page:
在您的页面中：
<a4j:jsFunction name="doAwesomeness" action="#{awesomeBean.awesomeMethod}"/>
Good luck!
祝你好运！

jQuery ajax request and JSF ajax request uses different js library's , I don't think there is a point in trying to mix those to too much...
jQuery ajax 请求和 JSF ajax 请求使用不同的 js 库，我认为尝试将它们混合太多没有意义......
If you whish to fire a JSF managed bean action from jQuery you better use a hidden h:commandButtonfor that purpose...
如果您希望从 jQuery 触发 JSF 托管 bean 操作，您最好h:commandButton为此目的使用 hidden ...
JSF:
JSF：
<h:commandButton id="someId" action="#{someBean.someMethod}" style="display:none">
<f:ajax render="someId" execute="someId"/>
</h:commandButton>
if you want to pass some more hidden args you can add some more hidden JSF components ids in the hidden h:commandButtonexecuteattribute, that way their corresponding properties will be updated on server side...
如果您想传递更多隐藏的参数，您可以在隐藏h:commandButtonexecute属性中添加更多隐藏的 JSF 组件 ID ，这样它们的相应属性将在服务器端更新...
js
js
$("#someId").click();
On the other side , if you want to use managed bean data in servlets that corresponds to your jQuery calls you can always access that JSF managed data, like this : JSF - get managed bean by name
另一方面，如果您想在对应于您的 jQuery 调用的 servlet 中使用托管 bean 数据，您始终可以访问该 JSF 托管数据，如下所示：JSF - 按名称获取托管 bean

In the same vein as pointed out by islandguy, if you use Primefaces, you woud use the <p:remoteCommand/>command, as follows :
与 islandguy 指出的一样，如果您使用 Primefaces，您将使用以下<p:remoteCommand/>命令：
<script type="text/javascript">
doAwesomeness();
</script>
with :
和 ：
<p:remoteCommand name="doAwesomeness"
actionListener="#{awesomeBean.awesomeMethod}"
oncomplete="jsToExecuteOnAjaxSuccess()" />
Hope this helps..
希望这可以帮助..
