如何在jsf/primefaces ajax请求上设置超时? [英] How to set timeout on jsf/primefaces ajax request?

问题描述

我正在使用 JSF2/Primefaces ，我想知道如何使用jsf或primefaces实现超时回调?

我想使ajax请求的超时时间为30秒，如果请求超时，则可以做为回调.

解决方案

我将脚放在嘴里，调查了源代码，并谷歌搜索并且第一批点击之一是有关设置超时时间的 PrimeFaces论坛主题. /p>

由于这种结果(奇怪的是我没有提前这样做)，我打开了

等...它已经内置了

为了处理错误"，有一个onerror事件处理程序，该事件处理程序使用用于基本ajax处理的javascript函数的名称

<p:ajax timeout="30000" onerror="doMyErrorThing" ... />
<p:commandButton timeout="30000" onerror="doMyErrorThing"... />

function doMyErrorThing(...) {
    // do your thing
}

在这种情况下，要调用服务器端方法，请调用p:remoteCommand，所有方法都应根据您的需要

I am using JSF2/Primefaces and I was wondering how to implement a timeout callback either with jsf or primefaces ?

I want to make the timeout for the ajax request 30 seconds and if the request timed out do something as a callback .

解决方案

I put my foot where my mouth is and investigated the source and found a hint. Not to clear but a start so I did some quick Googling and one of the first hits was a PrimeFaces forum topic about setting the timeout

As a result of this (weird that I did not do that upfront), I opended the documentation and searched for timeout. Lots of hits and it in the end turned out you could do

<p:ajax timeout="30000" ... />
<p:commandButton timeout="30000" ... />

etc... So it is already built in

For acting on the 'error' there is the onerror eventhandler which takes the name of a javascript function for basic ajax handling

<p:ajax timeout="30000" onerror="doMyErrorThing" ... />
<p:commandButton timeout="30000" onerror="doMyErrorThing"... />

function doMyErrorThing(...) {
    // do your thing
}

To call a server-side method in that case call a p:remoteCommand and all should be as you want it
