Topic: how to view the source code of the form rendered with JS

hi all,
in the new.js.erb and edit.js.erb ,render form all use the belowing code:

$("#addmember").html("<%= j render 'form' %>").hide().fadeIn();

and i can't view the source code after rendered.

now i just know the form id of Create action is "new_form",but edit action is not "edit_form" or "update_form"

how can view the source code of the form that rendered with js?
