jQuery Select Box Manipulation
Article Introduction：Core points
jQuery provides a variety of methods to manipulate drop-down boxes, including adding, removing, and changing options using methods such as append(), remove() and val(). Be sure to use the $() function to select the drop-down box before applying any method.
To get the current value of the selected option, use the val() method. You can use the text() method to get the text of the selected option. Multiple values ??can be retrieved using the each() function.
The onChange event in jQuery can be used to identify the selected options in the drop-down box. This event triggers a function that looks for the text of the selected option.

Manage the 'Select All/No Select All' checkbox functionality in a standalone container using jQuery
Article Introduction：This article introduces in detail how to use jQuery to implement the "Select All/No Select All" function of multiple sets of check boxes to ensure that each set of check boxes is operated in an independent HTML container without affecting each other. By adding specific class names to the parent container and the "Select All" check box, combined with jQuery's event listening, DOM traversal and property operations, we can control the selected status of all check boxes in the same group when clicking "Select All" and reverse linkage, that is, when all check boxes in the same group are automatically selected, or when any check box is unchecked, "Select All" is automatically cancelled.
