How do you know it isn't being passed? You don't use the id parameter anywhere. Did you mean to do something like this?

casper.evaluate(function(phone) {

    document.querySelector('#phone').setAttribute('value',phone);

}, {phone: index});

Here is how I did what i want using closure .

 casper.then(function(){

    phone_number   = casper.cli.get('phone');

    phone_password = casper.cli.get('password');

  });

  // Click on 'Search' button

  casper.then(function(){

    casper.waitForSelector('a.login',function(){

      casper.click('.login');

    });

  });

casper.then(function() {

    (function(ph,ps) {

      casper.thenEvaluate(function(phone,password) {

        document.querySelector('input#phone').setAttribute('value',phone);

        document.querySelector('input#password').setAttribute('value',password);

      //  document.querySelector('form').submit();

        }, { 

        phone    : ph,

        password : ps

      });

    })(phone_number,phone_password)

  

});

You can't do that, and it's not because of casper works but how javascript does.

Declare your vars at the top of your script:

var phone_number = casper.cli.get('phone');
var phone_password = casper.cli.get('password');

casper.start(); // ...
