Generally, you can't. You can write the code in a seperate file (using .js extension), but a determined surfer will be able to find it.
You could unescape small portions (see

There are programs around that obfuscate your code, and you should be able to obfuscate your code (at least to an extent) manually as well. The simplest trick is to do the opposite of Good coding practice (ie use meaningless and indecipherable variable names, don't comment your code etc)...

Try searching for "Obfuscate Javascript"

kind regards,


hey question again....

to not show up the javascript in client side /html is impossible, the other way is to encrypt the script, ok i agree...

but as i follow the tutorial in this URL Obfuscate Javascript

i must to trigger for encoding and the script must be in object so it has an id.
I can't do that because my script is located in the bottom of body, and it doesn't have any id or attribute

any idea??how to encrypt the script right from the page is opened, not triggered by event or attribute


kind regard,

i really wouldn't bother. it wont stop me from viewing the output in the dom in firebug, and only makes tiny revisions a major PITA.

even without firebug, i would immediately recognize the decoder as a function, and unescape the source to get the decoder. wouldn't take more than a few seconds to crack. i use 'crack' lightly, because the system doesn't even need a password.

it also increase the size of your script files considerably.

Why is it so important to 'hide' this code?

See Hide JavaScript code from the client for a nice discussion on the subject.
