Is there a way to update the value of an <input> element dynamically?

There is an input in a datalist that I am working with.

<input type="text" value="1" id="txtcount">

I am trying to obtain the new value of the input when the text changes.

I attempted to use the following code, but it did not work as expected.

<script>
//No global variables needed:)

$(document).ready(function(){
    // Get the initial value
   var $el = $('#txtcount');
   $el.data('oldVal',  $el.val() );


   $el.change(function(){
        // Store the new value
        var $this = $(this);
        var newValue = $this.data('newVal', $this.val());
   })
   .focus(function(){
        // Get the value when the input gains focus
        var oldValue = $(this).data('oldVal');
   });
});

Answer №1

Implement this -

$('#txtcount').on('keydown', function(event) {
  if (event.keyCode == 13) {
    var message = $('#txtcount').val();
    alert(message);
  } else {
    return true;
  }
});

Alternatively, you can retrieve the value on the "onTextChanged" event of TextField

Answer №2

what do you think of this approach?

$('#txtcount').change(function() { ... });

or maybe try this method instead

$("#txtcount").keypress(function() { .......});

or how about giving this one a shot

$('#txtcount').keyup(function() {..........});
