您现在习惯于像这样的简单jquery代码

Hi now used to simple jquery code as like this

$(document).ready(function(){
    $('.login__form').hide();
    $('.click').on('click', function(){
      $('.login__form').show();
    });
  $('.closePopUP').on('click', function(){
     $('.login__form').hide();
  })
  
});

body {
    background: #a7a7a7;
}
.closePopUP{position: absolute;
right: 8px;
top: 7px;
cursor: pointer;
border: solid 2px red;
border-radius: 50%;
font-size: 14px;
font-family: arial;
padding: 2px 6px;}
.login__form {
	width: 320px;
    padding: 20px;
    background: #fff;
    border-radius: 5px;
    border-top: 5px solid #ff4e50;
    margin: 0 auto;position:relative;
