Is there any way to get windows environment variables like %USERNAME% with javascript?

Question

is there any way to get windows environment variables like %USERNAME% with javascript using Adobe 10 pro?

Answer 1

There is a fair amount of Acrobat JavaScript and Acrobat knowledge need to sort all of this out.
The identity object holds a lot of sedative information. First, upon installation of Acrobat, only the login name is available in the identity object and the end user of the application needs to complete the "Name", "email" and "Organization Name" in the application's preferences. These are the only fields that are available to Acrobat JavaScript identity object as corporation, email, loginName, and name.
Using the instructions in The Acrobat JavaScript Console (Your best friend for developing Acrobat JavaScript) you can run the following script in the JS console to see the items of the identity object:
for(i in identity) {
console.println(i +": " + identity[i]);
and the following will appear in the console:
loginName: georgeK
name: George Kaiser
corporation: Example
email: [email protected]
true
The documentation states you need to use a trusted function to access this data, but you can access it at startup of Acrobat/Reader and add the properties of the identity object to an array:
// application variable to hold the properties of the identity object
var MyIdentity = new Array();
// loop through the properties of the identity object
for (i in identity) {
// place each property of the identity object into an element of the same name in the Identity array
MyIdentity[i] = identity[i];
console.println(i +": " + MyIdentity[i])
You access the items with:
var loginUser = MyIdentity[loginName];  // get the loginName property
In the user application level JavaScript file. See Acrobat Help / User JavaScript Changes for 10.1.1 (Acrobat | Reader) for the location of the application level folder you need to use.
I would change the name of the array used in this post so an untrusted user cannot get to your data. Some of this data can be used in hacking into a user's system.
