$.WebIM方法是主函数，用它可以覆盖local.chat中的基本配置，它可以完成聊天窗口的创建。$.WebIM.newWebIM方法是新创建一个窗口，只是消息的接收者是一个新用户。
复制代码 代码如下:
$.WebIM({
sender: userName,
receiver: receiver
});
$.WebIM.newWebIM({
receiver: receiver
});
remote.jsjac.chat.login(document.userForm);方法是用户登录到Openfire服务器
参数如下：
httpbase: window.contextPath + "/JHB/", //请求后台http-bind服务器url
domain: window["serverDomin"], //"192.168.5.231", // 192.168.5.231 当前有效域名
username: "", // 登录用户名
pass: "", // 密码
timerval: 2000, // 设置请求超时
resource: "WebIM", // 链接资源标识
register: true // 是否注册
remote.jsjac.chat.logout();是退出、断开openfire的链接
2、本地聊天应用核心代码 local.chat-2.0.js

这里的方法基本上是聊天窗口上的应用，主要是本地聊天程序的js、HTML元素的操作。如字体、字体大小、颜色、表情、消息的发送等，不涉及到聊天消息发送的核心代码，其中有用到发送远程消息的方法。
remote.jsjac.chat.sendMessage(text, receiver); 这个是发送远程消息的方法，参数1是消息内容、参数2是消息的接收者
如果你有看到这篇文章 它是一个单纯的WebIM本地的聊天界面。
3、远程聊天JavaScript核心代码，它是和jsjac库关联的。
