HTML: Form

Hit ENTER to Submit Form

Form Spec:

• If a form has only one input field then hitting enter in this field triggers form submit (ngSubmit)

• if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter doesn't trigger submit

  • If the form has no submit button, then the implicit submission mechanism must do nothing if the form has more than one field that blocks implicit submission.

• if a form has one or more input fields and one or more buttons or input[type=submit] then hitting enter in any of the input fields will trigger the click handler on the first button or input[type=submit] (ngClick) and a submit handler on the enclosing form (ngSubmit)

That means:

• If you only have one input, then you don't need input[type=submit]. Hit ENTER will submit the form.

• If you have more than one blocking input, then hitting ENTER will NOT submit the form unless you have a input[type=submit].

  • It also means on mobile, even you see search button (because your input is type search), hitting search won't do anything. The fix is to have a hidden submit button so 'search' button works.

For Angular:

• use ng-submit on the form instead of button(ng-click) to make sure ENTER works.

How to use keyboard 'Go' or 'Search' to submit form?

When you have submit button:

• by default the key press will submit the form

When you don't have submit button:

• if you ONLY have one input in the form, it'll work by press the 'Go'.

• if you have more than one input:

  • create a submit type button with style="visibility:hidden;position:absolute" (don't show and don't mess container layout)
