Post into a textarea and then get the result from another textarea

Let say I have this JS code:

function plus2(){
    print (2+2);
};

So I want to post this code into textarea#input at http://dean.edwards.name/packer/ and then get the result back from textarea#output.

Can use PHP Curl, Shell Curl or JQuery to do the job?

P.S.: 开发者_运维知识库By the way, there is bug in PHP Packer port and that's whay I am not using it.

PHP implementation of JSMin works well for me. Also, if you have server-side JS interpreter you can use UglifyJS, it's fast and provides a good compression.

Not really, no. It would need to be passed to a JavaScript engine at some point, so PHP/cURL is not going to be enough.

I recommend using an alternative server-side implementation of packer, or perhaps even YUI Compressor.
