var sendText = function() {
if (textSending) {
return;
}
textSending = true;
var msgInput = document.getElementById(talkInputId);
var msg = msgInput.value;
if (msg == null || msg.length == 0) {

}
var to = curChatUserId;
if (to == null) {

return;
}
var options = {

};
// 群组消息和个人消息的判断分支
if (curChatUserId.indexOf(groupFlagMark) >= 0) {

options.to = curRoomId;
} else if (curChatUserId.indexOf(chatRoomMark) >= 0) {

}

//easemobwebim-sdk发送文本消息的方法 to为发送给谁，meg为文本消息对象
conn.sendTextMessage(options);
//当前登录人发送的信息在聊天窗口中原样显示
var msgtext = Easemob.im.Utils.parseLink(Easemob.im.Utils.parseEmotions(encode(msg)));
appendMsg(curUserId, to, msgtext);
turnoffFaces_box();
msgInput.value = "";
msgInput.focus();
setTimeout(function() {

}, 1000);
};2.
//获取当前登录人的群组列表
conn.listRooms({
success : function(rooms) {
if (rooms && rooms.length > 0) {
buildListRoomDiv("contracgrouplist", rooms);//群组列表页面处理
if (curChatUserId === null) {
setCurrentContact(groupFlagMark + rooms[0].roomId);
$('#accordion2').click();
}
}
conn.setPresence();//设置用户上线状态，必须调用
