Checkbox value

Question

which difference makes the value in the input type = "checkbox"?

Answer 1

When submitting forms "name=value" pairs are only sent for checked checkboxes.

Since names can be duplicated (unlike IDs) this can effectively yield an array/list when checking multiple checkboxes using the same name.

Answer 2

By the way, in the meantime I added a live sample submit/response and went ahead and included checkboxes:
