如何使用jquery在移动模式下缩小菜单栏中的文本？

时间：2016-12-15 05:36:14

标签： javascript jquery html twitter-bootstrap mobile

我正在使用这个菜单栏，它有一个切换功能正常工作。但我的问题是，当用户点击菜单栏图标（在移动模式下）菜单栏从左到右打开，如果用户再次点击它，菜单栏会关闭，但它缩小了文本内部的文本。基本上，我想关闭它没有缩小文本，关闭文本时也会向左移动。谁能告诉我，我的jquery代码中我做错了什么或丢失了什么？提前谢谢！

这是 DEMO ，效果很好，但缩小文字问题

$(document).ready(function(){
  $('.dropdown').hover(function(){
   $(this).addClass('open');
 }, function(){
   $(this).removeClass('open');
 });


$('#nav-toggle').click(function(){

 $(this).toggleClass('active');
$(".navbar-collapse").animate({width:"toggle"});

});

  $('#mobile-subnav').click(function(){
   if($('.second-nav .navbar-left').css('display') == 'block'){
    $('.second-nav .navbar-left').slideUp(function(){
     $(this).addClass('not-visible');
   });
    $(this).html('<i class="fa fa-bars"></i> Open Submenu');
  } else {
    $('.second-nav .navbar-left').slideDown(function(){
     $(this).removeClass('not-visible');
   });
    $(this).html('<i class="fa fa-close"></i> Close Submenu');
  }
});
});

您需要在媒体查询中的css中添加以下规则。

ul.nav.navbar-nav.navbar-left {
  width: 240px;
  float: right;
}

此外，您的标记在很多地方都不匹配。结帐：https://jsfiddle.net/0ghv6the/1/我的更改。
