How to Detect Pressing Enter on the Keyboard Using Jquery

How can I detect pressing Enter on the keyboard using jQuery?

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!');
    }
});

Jquery: how to trigger click event on pressing enter key

try out this....

$('#txtSearchProdAssign').keypress(function (e) {
 var key = e.which;
 if(key == 13)  // the enter key code
  {
    $('input[name = butAssignProd]').click();
    return false;  
  }
});

$(function() {

  $('input[name="butAssignProd"]').click(function() {
    alert('Hello...!');
  });

  //press enter on text area..

  $('#txtSearchProdAssign').keypress(function(e) {
    var key = e.which;
    if (key == 13) // the enter key code
    {
      $('input[name = butAssignProd]').click();
      return false;
    }
  });

});

jquery detect enter key on dynamically created textbox

Use .on for dynamic HTML - detect a keyup event and then detect if the key up was for the enter key:

$(".vocab-list").on("keyup", "#writeWord", function(e) {
    if (e.which == 13) {
        alert("Enter");
    }
});

Detect Enter key is pressed with jQuery

$('#txt').keydown(function (e) {
    if (e.keyCode == 13) {
        alert('you pressed enter ^_^');
    }
})

On jsfiddle.

Update (June 2022)

Note that keyCode has been deprecated. Use KeyboardEvent.code or KeyboardEvent.key properties instead:

if (e.key === "Enter") {
   // Pressed enter
}

Keypress enter on button click in jQuery

try this.

var e = $.Event( "keypress", { which: 13 } );
$('#yourInput').trigger(e);

Capture an Enter Key Pressed anywhere on the page

$(document).keypress(function(e) {
  if(e.which == 13) {
    // enter pressed
  }
});
