Error Message Remove After Checkbox Fill in jQuery

If you are working on a form that requires users to fill in certain fields before submitting, you may want to provide them with error messages when they forget to fill in a required field. However, these error messages should disappear once the user has filled in the field. In this situation, jQuery can be used to remove the error message after the user fills in the required field.

Method 1: Using .change() Function

The first method involves using the .change() function to detect when the user has checked the checkbox. We can then use the .hide() function to hide the error message.


    $(document).ready(function(){
      $('#checkbox').change(function(){
        $('#error-message').hide();
      });
    });

document.ready: This function ensures that the code is executed only after the HTML document has finished loading.
#checkbox: This is the ID of the checkbox that needs to be checked.
#error-message: This is the ID of the error message that needs to be hidden.
.hide(): This function hides the error message.

Method 2: Using .prop() Function

The second method involves using the .prop() function to check whether the checkbox is checked or not. We can then use the .hide() function to hide the error message.


    $(document).ready(function(){
      $('#checkbox').click(function(){
        if($(this).prop('checked')){
          $('#error-message').hide();
        }
      });
    });

document.ready: This function ensures that the code is executed only after the HTML document has finished loading.
#checkbox: This is the ID of the checkbox that needs to be checked.
#error-message: This is the ID of the error message that needs to be hidden.
.click(): This function detects when the user clicks on the checkbox.
$(this): This refers to the checkbox that was clicked.
.prop('checked'): This checks whether the checkbox is checked or not.

Both of these methods are effective in removing error messages after a user fills in a required field. You can choose the one that works best for your situation.
