jQuery's method for judging common states such as display and hide_jquery

The example in this article describes how jQuery determines common states such as display and hide. Share it with everyone for your reference. The specific method is as follows:

Display: show() display:block;

Hide: hide() display:none;

When switching between display and hiding, you need to determine whether it is displayed or hidden at the moment. The following methods are commonly used to determine the conditions:

1.

Copy code The code is as follows:

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

2. First add a class identifier to the Dom element of thisNode, for example, change the identifier to class="showFlag", the judgment is as follows

Copy code The code is as follows:

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

In the same way, other contents of thisNode can also be judged, such as the number of sub-elements, text content, etc., based on specific needs.

I hope this article will be helpful to everyone’s jQuery programming.
