How to Use jQuery to display and hide common status judgments _ jquery-js tutorial

This article mainly introduces jQuery's methods for displaying and hiding common States. For more information, see 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. 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:

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.
