Not in the view-source.I meant Inspect source tab.

My Idea is this.

If i declare a function like this - 

function reloadWhenUserEditJSFile(){

location.reload()

}

and if there an event to call that function when user edit js file using Inspect source tab then probably i can stop user from editing file using browser Inspect source tab.

Oh well, you mean the developer tool.

Why would you expect JS to run again when you change the developer tool?

When the page is with the user, it is not your property anymore,
only your intelectual property, so why this primordial wish to control the 
user?

If you want to have some control over the page, 
use serverside programming, [or flash, as long as it lasts].

No. Web page script don't have access to the Developer Tools or any part of
it.

AFAIK, any JS file opened in the Developer Tools' Sources tab is just a
copy. Any changes to the JS code is not applied to the one which is used by
the web page.

For global variable it's a copy but not inside a function.You can change function content and javascript takes that new content into run time.

Correct.

> Web page

There is no “web page”.

<script type="text/javascript">
  console.log("You are wrong.");
</script>

Yes, it is, but only until the window/tab is reloaded.

There is no “web page”.

What is the definition of “web page”¿

     Nope.

  1) It is the user's system.  All he would have to do is use a
browser that did not have that event or have it enabled.  (I do not
know of any such event anyway.)

  2) I used to hack a former ISP's usage page.  I had a limit of so
many gigabytes per month.  There was a way to see how much I had used.
Unfortunately, the page was hard-coded to just a couple of months, and
they did not update the page each month.

     Tired of this, I took a look at the source, modified it to cover
the month I wanted, and then executed it.  It worked, and I got my
usage statistics that I was entitled to.

     This did not change their version of the page.

     I have no idea if I could have seen the statistics for anyone
else or if I could have gotten at anything else.  That would have been
dependent on their security system of which I know naught.

Sincerely,

Gene Wirchenko
