[Ashish Moghe]

current - The table where your user data is present.

----------------------------------------------------------------------------------------------------------------------------

var gr = new GlideRecord("sys_user");

/*

    * For users variable.

    * There are two field in the form 

    * 1. contains single field.

         * eg. FirstName LastName

    * 2. field for email Id

*/

var users = [current.getValue('u_name')];

var newuser = [],

    userslen = users.length,

    b = 0;

for (var i = 0; i < users.length; i++) {

    var k = users[i].split(" ");

    newuser.push(k);

}

for (b; b < newuser.length; b++) {

    var first = newuser[b][0];

    var last = newuser[b][1];

    var id = current.getValue('u_candidate_emailid');

    var userId = newuser[b][0].toLocaleLowerCase() + "." + newuser[b][1].toLocaleLowerCase();

    gr.newRecord();

    gr.setValue('user_name', userId);

    gr.setValue('first_name', first);

    gr.setValue('last_name', last);

    gr.setValue('email', id);

    gr.insert();

}
