这些 Ruby 变量有什么问题？

Question

I am trying to assign two variables and write a simple inline Ruby if statement within a method. I am getting an unexpected tidentifier keyword_end , indicating ^ at the end of the each variable names on all four lines;

1st_excl_checkbox = @browser.radio(:id => "opt2")
2nd_excl_checkbox = @browser.radio(:id => "opt1")
1st_excl_checkbox.set if 1st_excl_checkbox.exists?
2nd_excl_checkbox.set if 1st_excl_checkbox.exists?

Answer 1

You cannot have variables begin with a number. Rename your variables to first_excl_checkbox and second_excl_checkbox and you'll be good to go.

Answer 2

The problem is in the name of the variables. In the ruby they can not start with a digit.
