現(xiàn)在有三個(gè)函數(shù)，都在componentDidMount()生命周期中

componentDidMount() {

這里一直監(jiān)聽(tīng)
 _self.clientScript.subscribe('/topic/situation-transmit',function (data) {

                    var returnData = eval('(' + data.body + ')');
                    var date = new Date();
                    var showTime = date.getHours() + ':' + date.getMinutes() + ':' + date.getSeconds();
                    console.log(showTime + ' = 接收到的數(shù)據(jù) = ')
                    console.log(returnData.data);

                    _self.setState({
                        quantity: returnData.data['basicMessage']
                    })
})

開(kāi)始發(fā)第一個(gè)消息
_self.clientScript.send(
    '/topic/graduation-receive',
    {},
    JSON.stringify({
        topic: '/topic/situation-transmit',
        interval: 1,
        screenType: 'situation'
    })
);

這是第二個(gè)函數(shù)，我希望在發(fā)送第一個(gè)消息后，監(jiān)聽(tīng)到返回的數(shù)據(jù)，再發(fā)第二個(gè)消息，應(yīng)該怎么實(shí)現(xiàn)？，不想放到監(jiān)聽(tīng)里面，因?yàn)楸O(jiān)聽(tīng)會(huì)一直執(zhí)行下面這個(gè)函數(shù)
_self.clientScript.send(
    '/topic/graduation-receive',
    {},
    JSON.stringify({
        topic: '/topic/situation-transmit',
        interval: 1,
        screenType: 'situation'
    })
);


}
