Jquery: how to trigger click event on pressing enter key

Question 1

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;
    }
  });

});

Question 2

Try This

$('#twitterSearch').keydown(function(event){ 
    var id = event.key || event.which || event.keyCode || 0;   
    if (id == 13) {
        $('#startSearch').trigger('click');
    }
});

Hope it helps you

Question 3

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

I also just found Submitting a form on 'Enter' which covers most of the issues comprehensively.

Question 4

You were almost there. Here is what you can try though.

$(function(){
  $("#txtSearchProdAssign").keyup(function (e) {
    if (e.which == 13) {
      $('input[name="butAssignProd"]').trigger('click');
    }
  });
});

I have used trigger() to execute click and bind it on the keyup event insted of keydown because click event comprises of two events actually i.e. mousedown then mouseup. So to resemble things same as possible with keydown and keyup.

Here is a Demo

Question 5

Another addition to make:

If you're dynamically adding an input, for example using append(), you must use the jQuery on() function.

$('#parent').on('keydown', '#input', function (e) {
    var key = e.which;
    if(key == 13) {
        alert("enter");
        $('#button').click();
        return false;
    }
});

UPDATE:

An even more efficient way of doing this would be to use a switch statement. You may find it cleaner, too.

Markup:

<div class="my-form">
  <input id="my-input" type="text">
</div>

jQuery:

$('.my-form').on('keydown', '#my-input', function (e) {
  var key = e.which;
  switch (key) {
  case 13: // enter
    alert('Enter key pressed.');
    break;
  default:
    break;
  }
});

Question 6

Are you trying to mimic a click on a button when the enter key is pressed? If so you may need to use the trigger syntax.

Try changing

$('input[name = butAssignProd]').click();

to

$('input[name = butAssignProd]').trigger("click");

If this isn't the problem then try taking a second look at your key capture syntax by looking at the solutions in this post: jQuery Event Keypress: Which key was pressed?

Question 7

Just include preventDefault() function in the code,

$("#txtSearchProdAssign").keydown(function (e) 
{
   if (e.keyCode == 13) 
   {
       e.preventDefault();
       $('input[name = butAssignProd]').click();
   }
});

Question 8

This is my preferred solution.

    $("#text").keyup(function(event) {
        if (event.which === 13) {
            $("#submit").click();
        }
    });

Super simple, super jQuery.

Question 9

Try This

<button class="click_on_enterkey" type="button" onclick="return false;">
<script>
$('.click_on_enterkey').on('keyup',function(event){
  if(event.keyCode == 13){
    $(this).click();
  }
});
<script>

Question 10

Jquery: Fire Button click event Using enter Button Press try this::

tabindex="0" onkeypress="return EnterEvent(event)"

 <!--Enter Event Script-->
    <script type="text/javascript">
        function EnterEvent(e) {
            if (e.keyCode == 13) {
                __doPostBack('<%=btnSave.UniqueID%>', "");
            }
        }
    </script>
    <!--Enter Event Script-->

Question 11

You can use this code

$(document).keypress(function(event){
    var keycode = (event.keyCode ? event.keyCode : event.which);
    if(keycode == '13'){
       alert('You pressed a ENTER key.');
    }
});

Question 12

     $('#Search').keyup(function(e)
        {
            if (event.keyCode === 13) {
            e.preventDefault();
            var searchtext = $('#Search').val();
            window.location.href = "searchData.php?Search=" + searchtext + '&bit=1';
            }
        });

Question 13

This appear to be default behaviour now, so it's enough to do:

$("#press-enter").on("click", function(){alert("You `clicked' or 'Entered' me!")})
