What if there was a magical jQuery method that could automatically trigger a callback function? What could it possibly be named?

Is there a way to load only images and iframes, similar to the .load() function? I want to automatically add a selector element into the "this" variable for this purpose.

$('document').ready(function({
  $('a').<Something to trigger the code below on page load>(function(){
    // Placeholder is used to temporarily store the href attribute so that the link does not navigate to another webpage.
    $(this).attr('placeholder',$(this).attr('href'));
    $(this).attr('href','javascript:');
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<a href="www.example.com">My Link</a>

Answer №1

Are you aiming for a straightforward solution with this code snippet? :

$('document').ready(function({
  $('a').each(function(){
    $(this).attr('placeholder',$(this).attr('href'));
    $(this).attr('href','javascript:');
  });
});

The usage of $('element').each enables looping through each element, utilizing $(this) within the closure to make modifications directly.

Answer №2

One of the key features of jQuery is its support for chaining, making it possible to streamline and optimize your code. The following snippet demonstrates this concept:

$('document').ready(function({
  $('a').each(function() {
    var link$ = $(this);
    link$.attr('placeholder',link$.attr('href'))
      .attr('href','javascript:void(0)');
  });
});

It's important to note that each time you use $(this), a new jQuery wrapper is created around this. To improve performance, consider storing this wrapper in a variable.
