asp.net mvc: why is Html.CheckBox generating an additional hidden input

Question

I just noticed that Html.CheckBox(\"foo\") generates 2 inputs instead of one, anybody knows why is this so ?

Answer 1

This is not a bug! It adds the possibility of having always a value, after posting the form to the server. If you want to deal with checkbox input fields with jQuery, use the prop method (pass the 'checked' property as the parameter). Example: $('#id').prop('checked')
