Disable and Enable submit button in jquery

Question

I am using jquery to disable the submit button and load loading image,

In submit button I am using the folowing :

<div id="registerbtn" name="registerbtn">
<input type="submit" class="btn btn-primary" icon="ok white" value="Register" id="register" name="register"/>
</div>
<div class="span4" style="display:none;" id="loadingtext">
                            <?php echo  $imghtml=CHtml::image('images/loading.gif');?>                      
                        </div>

and in JQuery, I am using following code :

$(document).ready(function() {

    $('#register').click(function() {
        $('input[type="submit"]').attr('disabled','disabled');

     });
        $("#loadingtext").show();
    });
});

When I do this, then this button is disabled permanently, but if I want to remove then what should I do ??

Answer 1

Use .prop() method and use the $(this) to reference the target element within the callback function

jQuery(function($) {

  const $register = $("#register"),
        $loading = $("#loading");

  $register.on("click", function() {
  
    $(this).prop('disabled', true);
    $loading.show();
    
    setTimeout(function() {
      $register.prop('disabled', false);
      $loading.hide();
    }, 2000);

  });

});

<input id="register" value="Register" type="submit">
<div id="loading" style="display:none;">Wait 2 sec...</div>
