1. 命令行：

   phantomjs ––remote-debugger-port=9000 netlog.js http://www.vip.com

   

2. 在浏览器打开：

   http://localhost:9000/

   

   

3. 在console中执行如下命令：

   __run()

   

   在调试OK

   

If you need to nicely debug a page in PhantomJS you can use remote debugging feature.

First you have to create a file test.js with following contents:
require(‘webpage’).create().open(“http://localhost/yourproject.html”);
Now you do:

1. Run in terminal phantomjs ––remote-debugger-port=9000 test.js
   
2. Open in browser (ex. Chrome) page localhost:9000
   
3. There should be a link with title about:page – follow that link
   
4. A remote debugger (similar to Chrome) will open as a page. Type in its console (bottom left icon)__run() and run it (press enter)
   
5. Open again localhost:9000 in a new tab, now you should see one more link – follow it
   
6. You opened the debugger for your page
   

   If you want to set breakpoints before page will run then replace your test.js contents with:
   

   
   

   Now you do:
   

7. Run in terminal phantomjs –remote-debugger-port=9000 test.js
   
8. Open in browser (ex. Chrome) page localhost:9000
   
9. There should be a link with title about:page – follow that link
   
10. A remote debugger (similar to Chrome) will open as a page. Type in its console (bottom left icon)__run() and run it (press enter)
    
11. Open again localhost:9000 in a new tab, now you should see one more link – follow it
    
12. Go back to first tab and continue script execution (it should be stopped at debugger point)
    
13. Go back to second tab and set your desired break points. When you set them continue script execution (it should be stopped at debugger point)
    
14. Now inspect your code.
