You can also use javascript void 0  to prevent form submission    lt form action  javascript void 0   method  post  gt       lt label for    gt Search lt  label gt       lt input type  text  gt       lt button type  sybmit  gt Submit lt  button gt   lt  form gt     x000D   x000D   lt form action  javascript void 0   method  post  gt  x000D       lt label for    gt Search lt  label gt  x000D       lt input type  text  gt  x000D       lt button type  sybmit  gt Submit lt  button gt  x000D   lt  form gt  x000D   x000D   x000D

Something I have not seen answered here  when you tab through the elements on the page  pressing Enter when you get to the submit button will trigger the onsubmit handler on the form  but it will record the event as a MouseEvent  Here is my short solution to cover most bases   This is not a jQuery-related answer  HTML   lt form onsubmit  return false   method post gt     lt input type  text    gt  lt br   gt     lt input type  button  onclick  this form submit    value  submit via mouse or keyboard    gt     lt input type  button  onclick  submitMouseOnly event   value  submit via mouse only    gt   lt  form gt    JavaScript  window submitMouseOnly function evt       let allow  evt instanceof MouseEvent   amp  amp  evt x gt 0  amp  amp  evt y gt 0  amp  amp  evt screenX  gt  0  amp  amp  evt screenY  gt  0      if allow  evt tagName   FORM  evt target evt target form  submit        To find a working example  https   jsfiddle net nemesarial 6rhogva2

You could make a JavaScript method to check to see if the Enter key was hit  and if it is  to stop the submit    lt script type  text javascript  gt    function noenter       return   window event  amp  amp  window event keyCode    13      lt  script gt    Just call that on the submit method

Disallow enter key anywhere  If you don t have a  lt textarea gt  in your form  then just add the following to your  lt form gt     lt form     onkeydown  return event key     Enter    gt    Or with jQuery     document  on  keydown    form   function event         return event key     Enter         This will cause that every key press inside the form will be checked on the key  If it is not Enter  then it will return true and anything continue as usual  If it is Enter  then it will return false and anything will stop immediately  so the form won t be submitted   The keydown event is preferred over keyup as the keyup is too late to block form submit  Historically there was also the keypress  but this is deprecated  as is the KeyboardEvent keyCode  You should use KeyboardEvent key instead which returns the name of the key being pressed  When Enter is checked  then this would check 13  normal enter  as well as 108  numpad enter    Note that   window  as suggested in some other answers instead of   document  doesn t work for keydown keyup in IE lt  8  so that s not a good choice if you re like to cover those poor users as well   Allow enter key on textareas only  If you have a  lt textarea gt  in your form  which of course should accept the Enter key   then add the keydown handler to every individual input element which isn t a  lt textarea gt      lt input     onkeydown  return event key     Enter    gt   lt select     onkeydown  return event key     Enter    gt        To reduce boilerplate  this is better to be done with jQuery     document  on  keydown     input not textarea    function event        return event key     Enter         If you have other event handler functions attached on those input elements  which you d also like to invoke on enter key for some reason  then only prevent event s default behavior instead of returning false  so it can properly propagate to other handlers     document  on  keydown     input not textarea    function event        if  event key     Enter             event preventDefault                Allow enter key on textareas and submit buttons only  If you d like to allow enter key on submit buttons  lt input button type  submit  gt  too  then you can always refine the selector as below     document  on  keydown     input not textarea  not  submit    function event                     Note that input type text  as suggested in some other answers doesn t cover those HTML5 non-text inputs  so that s not a good selector

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   lt input type  button  gt    than using this   lt input type  submit  gt

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

There are many good answers here already  I just want to contribute something from a UX perspective  Keyboard controls in forms are very important  The question is how to disable from submission on keypress Enter  Not how to ignore Enter in an entire application  So consider attaching the handler to a form element  not the window  Disabling Enter for form submission should still allow the following   Form submission via Enter when submit button is focused  Form submission when all fields are populated  Interaction with non-submit buttons via Enter   This is just boilerplate but it follows all three conditions   x000D   x000D     form   on  keypress   function e         Register keypress on buttons     attr     e target  attr  type      if   attr      button      attr      submit         return true            Ignore keypress if all fields are not populated    if  e which     13  amp  amp   fieldsArePopulated this         return false          x000D   x000D   x000D

I think it s well covered with all the answers  but if you are using a button with some JavaScript validation code you could just set the form s onkeypress for Enter to call your submit as expected    lt form method  POST  action       onkeypress  if event keyCode    13  mySubmitFunction this   return false   gt    The onkeypress JS could be whatever you need to do  There s no need for a larger  global change  This is especially true if you re not the one coding the app from scratch  and you ve been brought into fix someone else s web site without tearing it apart and re-testing it

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    lt form action       gt     lt  -- Prevent implicit submission of the form -- gt     lt button type  submit  disabled style  display  none  aria-hidden  true  gt  lt  button gt      lt  --     -- gt      lt button type  submit  gt Submit lt  button gt   lt  form gt    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

I needed to prevent only specific inputs from submitting  so I used a class selector  to let this be a  global  feature wherever I need it    lt input id  txtEmail  name  txtEmail  class  idNoEnter         gt    And this jQuery code       idNoEnter   keydown function  e      if  e keyCode    13        e preventDefault              Alternatively  if keydown is insufficient       idNoEnter   on  keypress keydown keyup   function  e       if  e keyCode    13         e preventDefault               Some notes   Modifying various good answers here  the Enter key seems to work for keydown on all the browsers  For the alternative  I updated bind   to the on   method   I m a big fan of class selectors  weighing all the pros and cons and performance discussions  My naming convention is  idSomething  to indicate jQuery is using it as an id  to separate it from CSS styling

Use      Validate your form using the jQuery onsubmit function    It ll really work       document  ready function          form  submit e          e preventDefault           if validation              document form1 submit                function validation           Your form checking goes here      lt form id  form1  method  POST  action    gt         Your form data  lt  form gt

Instead of preventing users from pressing Enter  which may seem unnatural  you can leave the form as is and add some extra client-side validation  When the survey is not finished the result is not sent to the server and the user gets a nice message telling what needs to be finished to complete the form  If you are using jQuery  try the Validation plugin   http   docs jquery com Plugins Validation  This will require more work than catching the Enter button  but surely it will provide a richer user experience

In my case I had a couple of jQuery UI autocomplete fields and textareas in a form  so I definitely wanted them to accept Enter  So I removed the type  submit  input from a form and added an anchor  lt a href    id  btn  gt Ok lt  a gt  instead  Then I styled it as a button and added the following code        btn    click  function  event        event preventDefault        if   validateData                  form frm    append    lt input type  submit  id  frm-submit  style  display none   gt  lt  input gt              setTimeout  function         frm-submit    click       500              return false        If a user fills all required fields  validateData   succeeds and the form submits

A completely different approach    The first  lt button type  submit  gt  in the form will be activated on pressing Enter  This is true even if the button is hidden with style  display none  The script for that button can return false  which aborts the submission process  You can still have another  lt button type submit gt  to submit the form  Just return true to cascade the submission  Pressing Enter while the real submit button is focussed will activate the real submit button  Pressing Enter inside  lt textarea gt  or other form controls will behave as normal  Pressing Enter inside  lt input gt  form controls will trigger the first  lt button type submit gt   which returns false  and thus nothing happens    Thus    lt form action       gt     lt  -- insert this next line immediately after the  lt form gt  opening tag -- gt     lt button type submit onclick  return false   style  display none   gt  lt  button gt      lt  -- everything else follows as normal -- gt     lt  --     -- gt     lt button type submit gt Submit lt  button gt   lt  form gt
