运行代码的JavaScript

Question

我有这样的功能：

function start_all(id) { 

document.getElementById('status').innerHTML = "Starting..."; 

start(id); // This print too a status on the "status" div like: ID started 

document.getElementById('status').innerHTML = "Done..."; 

} 

我的问题是，最后一行是在函数开始（ID）之前运行;我需要在订单上运行。

我的结果是：

Starting... 
Done... 
ID started 

我需要这样的：

Starting... 
ID started 
Done... 

Answer 1

function start_all(id) { 

document.getElementById('status').innerHTML = "Starting..."; 

start(id,function(){ 
document.getElementById('status').innerHTML = "Done..."; 

}); 

} 

这就是所谓的回调

Answer 2

如何：

document.getElementById('status').innerHTML = "Starting..."; 
 
var status_id = start(id) // a string that returns the text 'ID Started' 
 
document.getElementById('status').innerHTML = status_id; 
 
document.getElementById('status').innerHTML = "Done...";
