您好，我有一個要求，我需要等待確認才能完成。注意：我無法在點擊（大塊）內觸摸我的前輩的以下代碼或將它們包裹起來.then(function(){..});這是我嘗試過但給出錯誤的：async function showConfirmationAndWait(){    $.alertable.confirm('You sure?').then(function() {      return new Promise(function(res,rej){           res({confirmed:true});      });    }, function() {       return new Promise(function(res,rej){           res({confirmed:false});      });      });}  $('#await').on('click',function(){    var promiseObj =  await showConfirmationAndWait(); //throwing error        //...... big code with its own function call that i don't want to touch });問題： 我想等到確認完成而不用包裝老年人的整個代碼.then(function(){..});這是我嘗試過的：async function showConfirmationAndWait(){    $.alertable.confirm('You sure?').then(function() {      return new Promise(function(res,rej){           res({confirmed:true});      });    }, function() {       return new Promise(function(res,rej){           res({confirmed:false});      });      });}  $(function(){    $('#await').on('click',function(){        var promiseObj =  await showConfirmationAndWait(); //commented due to error         console.log('after await promiseObj',promiseObj);             //...... big code with its own function call that i don't want to touch    });}); <link href="https://cdn.rawgit.com/claviska/jquery-alertable/master/jquery.alertable.css" rel="stylesheet"/><script src="https://code.jquery.com/jquery-2.2.4.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/velocity/1.2.3/velocity.ui.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/velocity/1.2.3/velocity.min.js"></script><script src="https://rawgit.com/claviska/jquery-alertable/master/jquery.alertable.min.js"></script><button id="await">Show confirmation wait and proceed next line</button>
