How does jQuery determine common states such as display and hide?

This document describes how jQuery Judges common states such as display and hide. Share it with you for your reference. The specific method is as follows:

Show () display: block;

Hide: hide () display: none;

When switching between display and hide, you need to determine whether to display or hide at the moment. The following methods are often used to determine the condition:

1.

The Code is as follows:

If (thisNode. is (': Den den') {...} else {.......}

2. First, add a class ID to the Dom element of thisNode. For example, change the ID to class = "showFlag" and determine the following:

The Code is as follows:

If (thisNode. hasClass ('showflag') {...} else {......}

In the same way, other thisNode content, such as the number of child elements and text content, can be determined based on specific requirements.
