Javascript隱藏顯示div

Question

以下代碼是我的css文件。我在這裏想要做的是當我沒有選擇導航按鈕<a href="#navbar-more-show">時隱藏<div class="container navbar-more visible-xs">。但是，當我選擇導航按鈕時，容器導航欄將出現。這裏的問題是我不確定如何在默認情況下隱藏div類，它會一直顯示在我的頁面上，當我點擊一個導航按鈕時，我想讓它出現。

$(document).ready(function() { 
 
     $('a[href="#navbar-more-show"], .navbar-more-overlay').on('click', function(event) { 
 
     event.preventDefault(); 
 
     $('body').toggleClass('navbar-more-show'); 
 

 
     if ($('body').hasClass('navbar-more-show')) { 
 

 
      $('a[href="#navbar-more-show"]').closest('li').addClass('active'); 
 
     } else { 
 
      $('a[href="#navbar-more-show"]').closest('li').removeClass('active'); 
 
     } 
 
     return false; 
 
     }); 
 
    });

body.navbar-more-show { 
 
    overflow: hidden; 
 
} 
 
.animate { 
 
    -webkit-transition: all 0.3s ease-in-out; 
 
    -moz-transition: all 0.3s ease-in-out; 
 
    -o-transition: all 0.3s ease-in-out; 
 
    -ms-transition: all 0.3s ease-in-out; 
 
    transition: all 0.3s ease-in-out; 
 
} 
 
.navbar { 
 
    height: calc(100%); 
 
    max-height: 300px; 
 
    -webkit-transform: translate(0px, calc(-100% + 69px)); 
 
    transform: translate(0px, calc(-100% + 595px)); 
 
} 
 
.navbar .container:not(.navbar-more) { 
 
    padding: 0px;

.navbar-more-overlay {

Answer 1

像你需要添加代碼隱藏要素入手，您可以使用以下這些方法

$('#YOURDIV').show() // Show your div like display:block; 
$('#YOURDIV').hide() // Hide your div like display:none; 

Answer 2

從你的描述，它只是聽起來：

$(document).ready(function() { 
    $(".container.navbar-more.visible-xs").hide(); 
    // your other code... 
}
