How to exclude div in jquery

When using jQuery to operate HTML pages, you often encounter situations where you need to exclude certain elements. There are many ways to exclude elements. This article will introduce how to use jQuery to exclude div elements through examples.

1. Basic syntax

In jQuery, you can use the not() method to exclude certain elements. The not() method can receive a selector as a parameter to exclude unnecessary elements from the set of matching elements.

The basic syntax is as follows:

$(selector).not(selector)

Among them, the first selector parameter is the selector of the element to be operated, and the second selector parameter is the selector of the element to be excluded.

2. Exclude a single div element

Let’s look at a simple example first. Suppose there is the following HTML code:

<div>
  <div>Box 1</div>
  <div>Box 2</div>
  <div>Box 3</div>
  <div>Box 4</div>
  <div>Box 5</div>
</div>

Now we need to exclude one of the div elements with class "excluded" and only operate on other elements. We can use the following code:

$('.box').not('.excluded').css('background-color', 'gray')

In the above code, first use the selector ".box" to select all div elements with class "box", and then use the not() method to exclude divs with class "excluded" element. Finally, use the css() method to set the background color of these elements to gray.

3. Exclude multiple div elements

In addition to excluding a single div element, we can also exclude multiple elements. Consider the following HTML code:

<div>
  <div>Box 1</div>
  <div>Box 2</div>
  <div>Box 3</div>
  <div>Box 4</div>
  <div>Box 5</div>
  <hr>
  <div>Panel 1</div>
  <div>Panel 2</div>
  <div>Panel 3</div>
  <div>Panel 4</div>
  <div>Panel 5</div>
</div>

Now we need to exclude all elements with class "excluded", whether it is a div or other elements. You can use the following code:

$('*').not('.excluded').css('color', 'red')

In the above code, use the wildcard "*" to select all elements, then use the not() method to exclude elements with class "excluded", and finally use the css() method to remove the elements of these elements. Text color is set to red. It’s important to note that using wildcards will operate on all elements on the page, so only use them if you really need them.

4. Summary

This article introduces how to exclude div elements in jQuery. The not() method can be used to exclude unnecessary elements from the matched element set, thereby achieving operations on the required elements. It should be noted that the excluded rule can be a selector for one or more elements, or it can be a wildcard. In actual use, the appropriate method should be selected according to the specific situation to avoid unnecessary effects.
