问题:

I need to execute a button click event upon pressing key enter.

As it is at the moment the event is not firing.

Please Help me with the syntax if possible.

$(document).on("click", "input[name='butAssignProd']", function () {
   //all the action
});

this is my attempt to fire click event on enter.

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

回答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;
    }
  });

});

Try This

$('#twitterSearch').keydown(function(event){ 
    var keyCode = (event.keyCode ? event.keyCode : event.which);   
    if (keyCode == 13) {
        $('#startSearch').trigger('click');
    }
});

Hope it helps you



回答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.



回答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



回答5:

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?



回答6:

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;
  }
});


回答7:

Just include preventDefault() function in the code,

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


回答8:

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>


回答9:

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

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

You can try it in this JSFiddle

Tested on: Chrome 56.0 and Firefox (Dev Edition) 54.0a2, both with jQuery 2.2.x and 3.x



回答10:

keyup is better than keypress to get the contents of input filed.
