jquery clear sibling div

As web applications continue to become more complex, JavaScript frameworks become more and more important. One of the most popular frameworks is jQuery, a popular JavaScript library that makes it easier to work with document elements, handle events, and create special effects. In this post, we will learn how to clear sibling DIVs using jQuery.

1. What is jQuery?

jQuery is a fast and concise JavaScript library that provides a simple and fast method for traversing and operating HTML documents, event processing, animation effects, data interaction, etc. It is an excellent cross-browser JavaScript code library. If needed, it can call existing JavaScript libraries to make your own JavaScript code richer.

2. jQuery’s method of clearing same-level DIVs

Clearing same-level DIVs means finding other elements (DIVs) at the same level in the DOM and deleting them. This is a common need and can be easily accomplished using jQuery.

The following HTML code shows an example of multiple DIVs:

<div class="demo-container">
    <div class="demo">Demo One</div>
    <div class="demo">Demo Two</div>
    <div class="demo">Demo Three</div>
    <div class="demo">Demo Four</div>
    <div class="demo">Demo Five</div>
</div>

We want to delete all DIVs except the first one.

1. Use the siblings() method

jQuery’s siblings() method returns all sibling elements at the same level as the selected element. In this method, you can use a selector to specify the elements you want to delete, as shown below:

$(document).ready(function(){
      $('.demo').siblings().remove();
});

In the above example, we selected the element with class demo and then used siblings() Method to select all elements adjacent to it. Then, use the remove() method to remove these elements.

2. Use the nextAll() method

jQuery’s nextAll() method returns all elements at the same level as the next selected element. In this method, you can also use a selector to specify the elements you want to delete, as shown below:

$(document).ready(function(){
     $('.demo').nextAll().remove();
});

In the above example, we selected the element with class demo and then used nextAll( ) method to select all elements following it. Then, use the remove() method to remove these elements.

3. Use nextUntil() method

jQuery’s nextUntil() method returns all elements between the selected element and the specified element. In this method, you can use a selector to specify the element you want to delete, as shown below:

$(document).ready(function(){
   $('.demo:first').nextUntil().remove();
});

In the above example, we selected the first element with class demo, and then used The nextUntil() method selects all elements between this element and all following elements. Then, use the remove() method to remove these elements.

The above three methods can all achieve the function of clearing DIVs of the same level. You can choose one of them according to your needs.
