我想实现一种信息为我的用户有关的进展情况。我已经发现了几个组件，如：

RichFaces的状态或< A HREF =htt​​p://component-showcase.icefaces.org/component-showcase/showcase.iface相对=nofollow> ICEfaces的onnection状态

所以，我想类似的东西添加到我的网页特别是对于Ajax请求。什么是实现它的最简单的方法是什么？我不喜欢使用其中的一个组成部分，而不是编程我自己一个人，但我怎么也想不到，有多少精力花费： - ）

我是心存感激的想法......

标准的JSF实现不为此提供了一个现成的应用组件。该 JSF 2.0规范然而概述了章13.3.5.2以下内容：

13.3.5.2监测活动对于所有的Ajax请求

此外，JavaScript API提供了 jsf.ajax.addOnEvent 的功能，可用于注册一个JavaScript函数   当任何Ajax请求/响应事件发生时将得到通知。请参阅14.4节注册回调   功能的更多细节。该 jsf.ajax.addOnEvent 函数接受一个JavaScript函数的参数，这将是   通知时，在任何Ajax请求/响应事件循环发生的事件。实现必须   确保被注册，必须调用按照概述的事件JavaScript函数   第表14-3事件。

您可以找到这里的Mojarra开发，其中包含基本的例子之一的博客。以下是相关的摘录：

 ＆LT; H3＆GT;状态：其中，/ H3＆GT;
＆LT; textarea的ID =statusAreaCOLS =40行=10只读=只读/＆GT;
 

有一个简单的文本区域，甚至没有上钩   到后端服务器的数据模型。

然后，在我们的JavaScript（用于演示，   在一个单独加载的文件，但它   可以很容易地在页面），我们   有：

  VAR statusUpdate =功能statusUpdate（数据）{
    变种statusArea =的document.getElementById（statusArea）;
    VAR文本= statusArea.value;
    文=文+姓名：+ data.source.id;
    如果（data.type ===事件）{
        文=文+事件：+ data.name +\ N的;
    }其他{//否则，它是一个错误
        文=文+错误：+ data.name +\ N的;
    }
    statusArea.value =文本;
};

//设置的statusUpdate功能听到网页上的所有事件
jsf.ajax.addOnEvent（statusUpdate）;
jsf.ajax.addOnError（statusUpdate）;
 

I would like to implement a kind of information for my users about the progress status. I have found several components like:

Richfaces status or IceFaces onnection Status

So, I would like to add something like that to my page especially for ajax requests. What's the easiest way to implement it? I would not like to use one of those components, rather programming my own one but I can't imagine how and how much effort it takes :-)

I am thankfull for ideas...

The standard JSF implementation doesn't provide a ready-to-use component for this. The JSF 2.0 specification however outlines the following in chapter 13.3.5.2:

13.3.5.2 Monitoring Events For All Ajax Requests

The JavaScript API provides the jsf.ajax.addOnEvent function that can be used to register a JavaScript function that will be notified when any Ajax request/response event occurs. Refer to Section 14.4 "Registering Callback Functions" for more details. The jsf.ajax.addOnEvent function accepts a JavaScript function argument that will be notified when events occur during any Ajax request/response event cycle. The implementation must ensure the JavaScript function that is registered must be called in accordance with the events outlined in Section TABLE 14-3 "Events".

You can find here a blog of one of the Mojarra developers which contains basic examples. Here's an extract of relevance:

<h3> Status:</h3>
<textarea id="statusArea" cols="40" rows="10" readonly="readonly" />

A simple textarea, not even hooked into the backend server data model.

Then in our javascript (for the demo, in a separately loaded file, though it could just as easily be in page) we have:

var statusUpdate = function statusUpdate(data) {
    var statusArea = document.getElementById("statusArea");
    var text = statusArea.value;
    text = text + "Name: "+data.source.id;
    if (data.type === "event") {
        text = text +" Event: "+data.name+"\n";
    } else {  // otherwise, it's an error
        text = text + " Error: "+data.name+"\n";
    }
    statusArea.value = text;
};

// Setup the statusUpdate function to hear all events on the page
jsf.ajax.addOnEvent(statusUpdate);
jsf.ajax.addOnError(statusUpdate);
