如何在进入下一行之前等待函数中的承诺

Question

How to wait the getstatus(statustable).then(function(response) to do before going to console.log("old"); where getstatus is an async function will return a new promise

    var count = "old";
    
     getstatus(statustable).then(function(response){
        console.log("changeing count")
        count = "new";
        console.log(count)

    });
    
    console.log("old");

Answer 1

Put console.log("old"); inside .then . Anything you want to execute for sure after the promise you will have to put it inside the .then or another .then chained after it.

If you want to write it in a sequential way you will have to use async/await .

Answer 2

You can await on getStatus

    var count = "old";
    
    await getstatus(statustable).then(function(response){
        console.log("changeing count")
        count = "new";
        console.log(count)

    });
    
    console.log("old");

The whole function that this is a part of will need to be async. If you can't change the function to async then you'll need to do as @Tushar Shahi suggested and put the last console log inside another then like below

    var count = "old";
    
    getstatus(statustable).then(function(response){
        console.log("changeing count")
        count = "new";
        console.log(count)

    }).then (() => {
        console.log("old");
    });
