在函数javascript中运行函数后的代码

Question

我有这个功能：

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在函数start（id）之前运行;我需要按顺序运行。

我的结果是：

Starting...
Done...
ID started

我需要这样：

Starting...
ID started
Done...

Answer 1

function start_all(id) {

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

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

});

}

这称为回调

Answer 2

这个怎么样：

＆＃13;

＆＃13;

   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...";

＆＃13;
