How to detect pressing Enter on keyboard using jQuery

Question

I would like to detect whether the user has pressed Enter using jQuery   How is this possible  Does it require a plugin   EDIT  It looks like I need to use the keypress   method    I wanted to know if anyone knows if there are browser issues with that command - like are there any browser compatibility issues I should know about

Try this to detect the Enter key pressed.

$(document).on("keypress", function(e){
    if(e.which == 13){
        alert("You've pressed the enter key!");
    }
});

See demo @ detect enter key press on keyboard

As the keypress event isn t covered by any official specification  the actual behavior encountered when using it may differ across browsers  browser versions  and platforms    x000D   x000D    document  keydown function event    x000D    if  event keyCode    event which     13    x000D         Cancel the default action  if needed x000D      event preventDefault    x000D        call function  trigger events and everything tou want to dd   ex   Trigger the button element with a click x000D          btn   trigger  click    x000D      x000D     x000D   lt script src  https   cdnjs cloudflare com ajax libs jquery 3 5 1 jquery min js  gt  lt  script gt  x000D   lt button id  btn  onclick  console log  Button Pressed     gt  amp nbsp lt  button gt  x000D   x000D   x000D    I hope it would be useful

I think the simplest method would be using vanilla javacript   document onkeyup   function event       if  event key     13        alert  enter was pressed

I found this to be more cross-browser compatible     document  keypress function event        var keycode   event keyCode    event which      if keycode     13             alert  You pressed a  enter  key in somewhere

I couldn t get the code posted by  Paolo Bergantino to work but when I changed it to   document  and e which instead of e keyCode then I found it to work faultlessly     document  keypress function e        if e which    13            alert  You pressed enter                 Link to example on JS Bin

The whole point of jQuery is that you don t have to worry about browser differences  I am pretty sure you can safely go with enter being 13 in all browsers  So with that in mind  you can do this     document  on  keypress  function e        if e which    13            alert  You pressed enter

A minor extension of Andrea s answer above makes the helper method more useful when you may also want to capture modified enter presses  i e  ctrl-enter or shift-enter   For example  this variant allows binding like      textarea   enterKey function      this  closest  form   submit        ctrl     to submit a form when the user presses ctrl-enter with focus on that form s textarea     fn enterKey   function  fnc  mod        return this each function                this  keypress function  ev                var keycode    ev keyCode   ev keyCode   ev which               if   keycode     13     keycode     10    amp  amp    mod    ev mod    Key                       fnc call this  ev                                        see also Ctrl Enter jQuery in TEXTAREA

In some cases  you may need to suppress the ENTER key for a certain area of a page but not for other areas of a page  like the page below that contains a header  lt div gt  with a SEARCH field   It took me a bit to figure out how to do this  and I am posting this simple yet complete example up here for the community    lt  DOCTYPE html gt   lt html xmlns  http   www w3 org 1999 xhtml  gt   lt head gt     lt title gt Test Script lt  title gt     lt script src   lib js jquery-1 7 1 min js  type  text javascript  gt  lt  script gt     lt script type  text javascript  gt          container  content input   keypress function  event          if  event keyCode    10    event keyCode    13            alert  Form Submission needs to occur using the Submit button             event preventDefault                       lt  script gt   lt  head gt     lt body gt       lt div class  container  gt         lt div class  header  gt           lt div class  FileSearch  gt             lt  -- Other HTML here -- gt           lt  div gt         lt  div gt         lt div class  content  gt           lt form id  testInput  action     method  post  gt           lt input type  text  name  text1    gt           lt input type  text  name  text2    gt           lt input type  text  name  text3    gt           lt input type  submit  name  Submit  value  Submit    gt           lt  form gt         lt  div gt       lt  div gt     lt  body gt   lt  html gt    Link to JSFiddle Playground  The  Submit  button does not do anything  but pressing ENTER from one of the Text Box controls will not submit the form
