导航栏中的错误？

时间：2017-04-23 07:40:45

标签： javascript jquery html css debugging

我的菜单出了点问题，我无法弄明白为什么。当我在响应式视图中测试我的代码时，它首先从汉堡包图标切换到水平导航栏时工作正常，但是......如果我点击汉堡包图标首先（一次下拉菜单和第二次关闭它）和然后调整屏幕大小，我的水平导航菜单消失。

这是Codepen中链接的代码。只需转到全视图并尝试这些步骤，看看你的想法！谢谢!!

4 个答案:

答案 0 :(得分：1)

在.menu中放置一个display : block !important;，函数slideToggle（）会在元素.menu中内嵌一个样式display:none，所以当你回到高分辨率时，.menu仍会显示：无

答案 1 :(得分：1)

函数slideToggle()切换显示属性，并将其添加到菜单的元素样式中，这使得它比使用类

更优先

因此要解决此问题，请在媒体屏幕display:block;

中将重要添加到min-width : 768px; 
@media only screen and (min-width : 768px) {
   .....
   .menu {
    display: block!important;
     .....
   }
}

答案 3 :(得分：0)

我已经创建了一个需要完成的事情的简短示例。添加了一些jquery代码，使其按照您想要的方式工作。

  

第1步 - 在窗口宽度上添加课程hide-nav 

      /* logic For window width */
  if ($(window).width() > 768) {
  //  $('.menu').addClass('hide-nav');
    $('.menu').addClass('show-nav');
  } else {
    $('.menu').removeClass('hide-nav');
  }
  

第2步 - 在窗口调整大小

上添加课程hide-nav 
      function resize() {
    if ($(window).width() < 768) {
      $('.menu').addClass('hide-nav');
      $('.menu').removeClass('show-nav');
    }
  else {

    $('.menu').addClass('show-nav');
}
  }

  $(window).resize(resize)
    .trigger('resize');

＆＃13;
＆＃13; 
$(document).ready(function() {
  $('#nav-icon4').click(function() {
    $(this).toggleClass('open');
    $(".menu").slideToggle("slow");
  });

  /* logic For window width */
  if ($(window).width() > 768) {
    //  $('.menu').addClass('hide-nav');
    $('.menu').addClass('show-nav');
  } else {
    $('.menu').removeClass('hide-nav');
  }
});

function resize() {
  if ($(window).width() < 768) {
    $('.menu').addClass('hide-nav');
    $('.menu').removeClass('show-nav');
  } else {

    $('.menu').addClass('show-nav');
  }
}

$(window).resize(resize)
  .trigger('resize');
