Prevent users from submitting a form by hitting Enter

Question

I have a survey on a website, and there seems to be some issues with the users hitting enter (I don\'t know why) and accidentally submitting the survey (form) without clicki

Answer 1

Not putting a submit button could do. Just put a script to the input (type=button) or add eventListener if you want it to submit the data in the form.

Rather use this

<input type="button">

than using this

<input type="submit">

Answer 2

In my specific case I had to stop ENTER from submitting the form and also simulate the clicking of the submit button. This is because the submit button had a click handler on it because we were within a modal window (inherited old code). In any case here's my combo solutions for this case.

    $('input,select').keypress(function(event) {
        // detect ENTER key
        if (event.keyCode == 13) {
            // simulate submit button click
            $("#btn-submit").click();
            // stop form from submitting via ENTER key press
            event.preventDefault ? event.preventDefault() : event.returnValue = false;
        }
    });

This use case is specifically useful for people working with IE8.

Answer 3

Section 4.10.22.2 Implicit submission of the W3C HTML5 spec says:

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

Note: Consequently, if the default button is disabled, the form is not submitted when such an implicit submission mechanism is used. (A button has no activation behavior when disabled.)

Therefore, a standards-compliant way to disable any implicit submission of the form is to place a disabled submit button as the first submit button in the form:

<form action="...">
  <!-- Prevent implicit submission of the form -->
  <button type="submit" disabled style="display: none" aria-hidden="true"></button>

  <!-- ... -->

  <button type="submit">Submit</button>
</form>

One nice feature of this approach is that it works without JavaScript; whether or not JavaScript is enabled, a standards-conforming web browser is required to prevent implicit form submission.

Answer 4

Giving the form an action of 'javascript:void(0);' seems to do the trick

<form action="javascript:void(0);">
<input type="text" />
</form>
<script>
$(document).ready(function() {
    $(window).keydown(function(event){
        if(event.keyCode == 13) {
    alert('Hello');
        }
    });
});
</script>

Answer 5

This works for me

jQuery.each($("#your_form_id").find('input'), function(){
    $(this).bind('keypress keydown keyup', function(e){
       if(e.keyCode == 13) { e.preventDefault(); }
    });
});

Answer 6

A nice simple little jQuery solution:

$("form").bind("keypress", function (e) {
    if (e.keyCode == 13) {
        return false;
    }
});
