jQuery's methods for judging common states such as show and hide

This article illustrates jQuery's methods of judging common states such as show and hide. Share with you for your reference. Here's how:

Display: show()   display:block;

Hidden: hide()     display:none;

When switching between show and hide, it is necessary to decide whether to show or hide at the moment. The following methods are commonly used to determine the condition:

1.

if(thisNode.is(':hidden')){......}else{.......}

2. First, add the class logo to the Dom element of thisNode. For example, change the logo to class="showFlag"

if(thisNode.hasClass('showFlag')){.......}else{......}

In the same way, you can also determine other contents of thisNode, such as the number of child elements, text contents, and so on, depending on your specific requirements.

I hope this article has been helpful to your jQuery programming.
