嗨，我有一个要求，我需要等待确认完成。

**注意：**我不能在click（大块）内触摸我的前辈的下面代码或用.then(function(){..}); Package 它们
这是我尝试过的，但给出了错误：

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
 });

字符串

**问题：**我想等到确认完成，而不是用.then(function(){..}); Package 整个代码
以下是我尝试过的：

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
    });
});
