Definition and usage

Detailed description

Given a jquery object that represents a collection of DOM elements, the. Not () method constructs a new jquery object with a subset of the matching elements. The applied selector detects each element, and the element that does not match the selector is included in the result.

Consider the following page with a simple list:

<ul>  <Li>List Item 1</Li>  <Li>List Item 2</Li>  <Li>List Item 3</Li>  <Li>List Item 4</Li>  <Li>List Item 5</Li></ul>

We can apply this method to a list item set:

$ (' Li '). Not (': even '). css (' background-color ', ' red ');

Remove a specific element

The second version of the. Not () method allows us to remove elements from a matching set, assuming that we have previously found these elements by other means. For example, imagine a list that has an ID applied to one of the items:

<ul>  <Li>List Item 1</Li>  <Li>List Item 2</Li>  <LiID= "Notli">List Item 3</Li>  <Li>List Item 4</Li>  <Li>List Item 5</Li></ul>

We can use the native JavaScript function getElementById () to read the third list item and then remove it from the JQuery object:

$ (' Li '). Not (document.getElementById (' Notli ')). CSS (' background-color ', ' red ');
