Using a key to execute a javascript

[Cainnech]

Hi guys,

I want to ask your ideas on something.

I want to add something to my javascripts to prevent them from being executed. Just call it like a sort of license. So when someone executes a script of mine, the script first checks online if it can be executed. If not, then it won't run, else it will run.

I could program the javascript to send check online and send a reply back. But that reply could be mimicked by the user by adapting the javascript, so that's not a very good solution.

The scripts where I want to add this are not scripts that are used on websites, they are scripts that are being used in applications. So basically I want to provide a sort of license system for HTA's.

Greets,

the only things that you reliably could suppress are serverside calls ... like XMLHttpRequests or such ... by using a session and a session id that must match ... all clientside JavaScript-code could be modified by a user at any time ...

kind regards

I was also thinking of using something like XMLHttprequest but how do you have that interrupt a script?

only if the script would ask the server during its runtime ... but the script would need to react in a appropriate way ... you basicly cannot interrupt a script itself in a reliable way ... but you might create a trap ... when the request is 'false' then the script will not get the needed response to continue ... so it would stop at this point ...
