What could be preventing my jQuery from updating the DOM properly?

I'm currently working on a login screen for an app that has a feature where clicking the "Not You?" button brings up a text-box to update the username displayed. However, I am facing an issue where the username only updates once and then fails to work again. Can anyone help identify what's incorrect with my jQuery code?

Here is the jQuery code in question:

var main = function(){
$('.not').click(function(){
    $('.login-wrap').fadeOut(300, function(){
        $('.not-you').fadeIn(300); 
    });
});

$('.enter').click(function(){
    $('.name').replaceWith($('.new-input').val());
    $('.not-you').fadeOut(300, function(){
        $('.login-wrap').fadeIn(300);
    });
  });
}

$(document).ready(main);

Appreciate the assistance!

Answer №1

In the documentation, it is explained that the .replaceWith() method can be used to remove content from the DOM and replace it with new content in a single call. However, there seems to be an issue where using this method for the first time replaces the entire element with the class 'name', causing problems thereafter.

Instead of

$('.name').replaceWith($('.new-input').val());

Consider trying

$('.name').html($('.new-input').val());

OR

$('.name').text($('.new-input').val());

You can also check here for reference.

Answer №2

When utilizing the replaceWith() method, you're essentially eliminating the entire element with a class of '.name'. As a result, when the code is run again, it won't be able to locate any elements with the class 'name'.

To resolve this issue, consider using the '.html()' method instead.

Answer №3

To modify the line that uses replaceWith(), you can utilize the code snippet below:

$('.title').replaceWith("<h1 class='title'>"+$('.new-heading').val()+"</h1>");

The function replaceWith() essentially swaps out the entire HTML element with the class of title.
