Question

代码 Demo

响应式菜单不能多次使用..

$(function() {     
  $('.reponsivemenu').css({
    'opacity': '0'
  });    
  $('a#showMenu').click(function() {    
    $('.reponsivemenu').css({
      'opacity': '1'
    });
    $(this).addClass('active');
    if ($('#showMenu').hasClass('active')) {
      $(this).click(function() {
        $('.reponsivemenu').css({
          'opacity': '0'
        });
        $(this).removeClass('active');
      });
    }

  });

});

它的代码只运行一次.. 什么是代码问题以及如何解决这个问题？

Answer 1

使用

$('a#showMenu').click(function() {


    if ($('#showMenu').hasClass('active')) {
      $('.reponsivemenu').css({
        'opacity': '0'
      });
      $(this).removeClass('active');
    } else {
      $('.reponsivemenu').css({
        'opacity': '1'
      });
      $(this).addClass('active');
    }

  });
