如何在jsf/primefaces ajax请求上设置超时?

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，并找到了提示.不知道是一个开始，所以我做了一些快速的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)，我打开了文档，然后搜索timeout.很多热门歌曲，最终证明您可以做到

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

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
