JavaScript 简单的实现 sleep功能 .

 1 function start(){
 2     // console.log("Request handle 'start' was called.");
 3 
 4     function sleep(milliSeconds){
 5         var startTime = new Date().getTime();
 6         while(new Date().getTime() < startTime + milliSeconds);
 7     }
 8 
 9     sleep(10000);
10     console.log("Request handle 'start' was called.");
11     return "Hello Start.";
12 }
13 
14 
15 function upload(){
16     console.log("Request handle 'upload' was called.");
17     return "Hello upload.";
18 }
19 
20 exports.start = start;
21 exports.upload = upload;

中的:

1     function sleep(milliSeconds){
2         var startTime = new Date().getTime();
3         while(new Date().getTime() < startTime + milliSeconds);
4     }
5 
6     sleep(10000);
