Not long ago wrote some code, all button click on a button to switch the state, did not want to use addClass removeClass thoughtful to control the state of the control, then I think that is wrong.
<html>
<head>
<script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$("ul li").click(function(e){
console.log(e.target);
$(e.target).toggleClass("active")
});
})
</script>
<style type="text/css">
.normal{
color:green;
}
.active{
color:red !important;
}
</style>
</head>
