How do I hide javascript code in a webpage?

Question

Is it possible to hide the Javascript code from the html of a webpage, when the source code is viewed through the browsers View Source feature?

I know it is possibl

Answer 1

Approach i used some years ago -

We need a jsp file , a servlet java file and a filter java file.

Give access of jsp file to user. User type url of jsp file .

Case 1 -

• Jsp file will redirect user to Servlet .
• Servlet will execute core script part embedded within xxxxx.js file and

• Using Printwriter , it will render the response to user .

• Meanwhile, Servlet will create a key file .

• When servlet try to execute the xxxx.js file within it , Filter
  will activate and will detect key file exist and hence delete key
  file .

Thus one cycle is over.

In short ,key file will created by server and will be immediatly deleted by filter .

This will happen upon every hit .

Case 2 -

• If user try to obtain the page source and directly click on xxxxxxx.js file , Filter will detect that key file does not exist .
• It means the request has not come from any servlet. Hence , It will block the request chain .

Instead of File creation , one may use setting value in session variable .
