jQuery method to switch the selected state of all check boxes_jquery

The example in this article describes how jQuery switches the selected state of all check boxes. Share it with everyone for your reference. The details are as follows:

This code is very simple and practical. It switches whether all checkboxes are selected through links

var tog = false;
// or true if they are checked on load 
 $('a').click(function() { 
  $("input[type=checkbox]").attr("checked",!tog); 
 tog = !tog; 
 });

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