運行代碼的JavaScript

Question

我有這樣的功能：

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..."; 

} 

我的問題是，最後一行是在函數開始（ID）之前運行;我需要在訂單上運行。

我的結果是：

Starting... 
Done... 
ID started 

我需要這樣的：

Starting... 
ID started 
Done... 

Answer 1

function start_all(id) { 

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

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

}); 

} 

這就是所謂的回調

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...";
