This doesn't really sound like a job for JavaScript. If you want the numbers hiding, you should do so at the server level. I'm not sure what template engine you're using, but where ever you assign 'anum' you should do it there.

the anum  is the called number  and we get it from a external xml gateway that hold all details

 

A friend gave me this

 

<script>

var a = '31sd232fsd12ddf143';

var b = a.substring(0, (a.length-4)) + '****';

alert(b);

</script>

 

but i am not so relative with js

Where do you substitute "{anum}" for the value in the server-side code? Even if it's a feed, you still need parse the template at some point. I'm guessing the last four digits are sensitive for some reason - otherwise why would you need to hide them? Using JavaScript would mean you're still sending the original, desensitised data to the client (so it would still be visible in the source). There might also be a delay in replacing the text, so the user sees the last four digits for a short amount of time. Also any user with JS disabled would always see the original data.

 

As I said, you need to use server-side code to properly sensitise data like this.

you are right
