This is probably a stupid question but I am confused...
I see an example in the 3d Edition of Agile Dev with Rails (page 539)
where a simple calculator view, with two text boxes for numbers and a
dropdown for what operation to perform, does not mention a submit
button
or gesture.
I don't understand that. Yes, the form_tag does indicate an :action
=> ,
but what triggers that if there is no <%= submit_tag 'Save' %>?
Browser dependent, but usually if you hit ENTER while in a text field
it will submit the form.
Or perhaps that form's submission is being triggered via javascript.
