1.创建消息

var ManagedClientStatus = {

  historyMessage: [],

  curMessage: null

}

ManagedClientStatus.addMessage = function (clientObj, statusCode) {

  var curMessage = {

    client: clientObj,

    statusCode: statusCode,

    createAt: new Date()

}

  if (ManagedClientStatus.curMessage === null) {

    ManagedClientStatus.curMessage = curMessage

  } else {

    ManagedClientStatus.historyMessage.push(curMessage)

    setTimerPush()

}

}

var setTimerPush = function () {

  var setTimer1 = setInterval(function () {

    if (ManagedClientStatus.curMessage === null) {

      if (ManagedClientStatus.historyMessage.length > 0) {

        ManagedClientStatus.curMessage = ManagedClientStatus.historyMessage[0]

        ManagedClientStatus.historyMessage.splice(0,1)

      } else {

        clearInterval(setTimer1)

}

}

  }, 500)

export default ManagedClientStatus

2.发送消息

   (这个模块在vue中使用)

created: function(){

//vue中深度检测变量

watch: {

  curClientMessage: {

    handler(newName, oldName) {

      console.log('obj.a changed');

    },

    deep: true，

   immediate:true

  }

}

//js本身的检测对象内部变量的变化

var the = this

Object.defineProperty(ManagedClientStatus, 'curMessage', {

  get: function () {

    return the.curClientMessage

  },

  set: function (value) {

    the.curClientMessage = value

  }

})

3.输出

将this.curClientMessage 的值输出到消息展示模块
