サブメニュー付きのブートストラップnavbar - クラス "disabled"を削除する方法@media width 768未満

Question

メインメニューのリンクを有効にするために "disabled"クラスを使用しました。しかし、メディア幅768でクラス「無効」を削除するにはどうしたらいいですか？小さな画面で「無効」クラス機能を無効にする方法は？ （768 @「メインメニュー1」に不要リンク）

if ($(window).width() > 768) { 
 
      $('ul.nav li.dropdown').hover(function() { 
 
       $(this).find('.dropdown-menu').stop(true, true).delay(600).fadeIn(200); 
 
      }, function() { 
 
       $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(600); 
 
      }); 
 
     }

Answer 1

はこのような何かを試していない、あなたは検査要素、ドロップダウンをホバーdisableクラス意志を確認することができますデモで

$(function(){ 
var $windowWidth = $(window).width(); 
$('ul.nav').on('mouseover','.dropdown',function(){ 
    if($windowWidth < 768){ 
     $(this).find('a').removeClass('disabled'); 
    } 
}); 
}); 

チェックを削除すること

$(function(){ 
 
\t var $windowWidth = $(window).width(); 
 
\t $('ul.nav').on('mouseover','.dropdown',function(){ 
 
\t  if($windowWidth < 768){ 
 
       $(this).addClass('open'); 
 
\t   $(this).find('a').removeClass('disabled'); 
 
\t  } 
 
\t }); 
 
});

Answer 2

if ($(window).width() < 768) { 
$(".dropdown.a").removeClass("disabled"); 
} 

Answer 3

768ピクセルの画面の下に無効クラスを削除するためにこれを使用します。

if ($(window).width() < 768) { 
    $('a.dropdown-toggle').removeClass('disabled'); 
} 

if ($(window).width() < 768) { 
 
    $('a.dropdown-toggle').removeClass('disabled'); 
 
} 
 
if ($(window).width() > 768) { 
 
      $('ul.nav li.dropdown').hover(function() { 
 
       $(this).find('.dropdown-menu').stop(true, true).delay(600).fadeIn(200); 
 
      }, function() { 
 
       $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(600); 
 
      }); 
 
     }
