This is an update to reflect the significant change in the OP's question:

Google Chat and Facebook both use XMPP(jabber) servers, as do most companies I know of that have internal instant messaging. 

The nice part about XMPP is that you get all of the "is typing" and other <code>presence</code>-based information without having to roll-your-own in javascript (bear in mind, you will still need to use javascript to pass XMPP requests back to the server, but XMPP has most of the features you'd need already built in).

Check out <a href="http://www.igniterealtime.org/projects/openfire/" rel="nofollow noreferrer">OpenFire</a>. It's a great XMPP server, totally open source, and they have a web-based version of their Spark client that is pretty nice. 

Or you could get a PHP library for XMPP (there are a few). But you'd still need to have the XMPP server running in the background for PHP to work with.

Here's a list of <a href="http://xmpp.org/software/libraries.shtml#php" rel="nofollow noreferrer">XMPP libraries for PHP</a> from <a href="http://xmpp.org" rel="nofollow noreferrer">XMPP.org</a>:

<ul>
<li>Eiffel</li>
<li>JAXL</li>
<li>Lightr</li>
<li>Missus</li>
<li>xmpphp</li>
</ul>

Or, if you want to keep things mostly browser-side, they also have a list of <a href="http://xmpp.org/software/libraries.shtml#javascript" rel="nofollow noreferrer">libraries for javascript</a>:

<ul>
<li>dojox.xmpp</li>
<li>js.io</li>
<li>JSJaC</li>
<li>strophe.js</li>
<li>xmpp4gwt</li>
<li>xmpp4js</li>
</ul>

blocks|key|106347|text|例如，如果您有一个文本区域#chat，那么您可以使用以下代码来附加事件：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|106348|document.getElementById('chat').addEventListener('keydown',+FUNCTION+HERE,+false);|code-block|syntax|javascript|106349|entityMap^0|D|5|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

For example, if you had an text area <code>#chat</code> then you could use this code to attach the event:

<pre><code>document.getElementById('chat').addEventListener('keydown', FUNCTION HERE, false);
</code></pre>

It was quie a discovery for me!

blocks|key|1656566|text|不久前，我开发了一个小型聊天应用程序，唯一的方法是经常检查chat数据库中的新条目，并获取比上次显示的消息更新的内容。同时，您可以检查用户的输入是否为空。如果是的话，什么也不做。如果不是，请在该用户名旁边的数据库中输入状态代码。如果有人在数据库中获取有关新消息的信息以及谁在线，则应该显示“用户正在键入”消息。我希望这让sense...let我知道如果不是。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1656567|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I made a small chat application a while ago, and the only way to do it is to frequently check for new entries in the chat database and fetch anything newer than the last displayed message. At the same time as all that, you can check to see if the user's input is empty. If it is, do nothing. If it isn't, enter a status code into the database beside that user's name. If anyone has that status in the database when you're fetching information about new messages and who is online, you should display the 'user is typing' message. I hope that makes sense...let me know if it isn't.

blocks|key|1357369|text|对于User1:如果您将聊天消息保存在每个键上，按下数据库，状态为:+sent=false并更新最后更新的日期。对于User2:您可以定期地查找sent=false存在的消息，并使用最后更新的用户输入消息。如果最后更新的日期超过10秒，您可以删除该消息，因为该人可能已经停止键入。这将使User2能够再次看到User1类型、停止和继续。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1357370|理想情况下，对此信息的轮询将是对数据库的现有调用的一部分，以减少额外的开销。|1357371|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

For User1: If you save the chat message on each key-press to the database, with a status: sent=false and update the last updated date.
For User2: you could pole periodically for the presence of a message where sent=false and use the last updated to update user is typing message. if the lastupdated date is more than a say ten seconds you could remove the message as that person may have stopped typing. This will allow User2 to see User1 typing, stopping and continueing again.

Ideally polling for this information will be part of an existing call to the database to reduce additional overhead.

Can someone illustrate how I can get typing status of the other party with javascript?

UPDATE

Can someone recommend a one-to-one open source chatting application,preferably written in PHP? I only found open source chatting rooms which are for chatting among all onliners,but I just need a one-to-one chatting.

Implementing web chat,how do I get typing status?

有人能说明我如何使用javascript获得对方的输入状态吗？更新有人能推荐一个一对一的开源聊天应用程序，最好用PHP编写吗？我只找到了开放源码的聊天室，这是为所有在线聊天，但我只是需要一对一的聊天。
