Javascript隱藏和顯示div

Question

下面的代碼是我的 CSS 文件。 我在這里嘗試做的是在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，會出現容器導航欄。 這里的問題是我不確定默認情況下如何隱藏 div 類，它一直出現在我的頁面上，我想讓它在我單擊導航按鈕時出現。

 $(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 { background-color: rgba(102, 102, 102, 0.55); display: none; height: 100%; left: 0px; position: fixed; top: 0px; width: 100%; z-index: 1029; } .navbar-more-show > .navbar-more-overlay { display: block; } .navbar-more-show > .navbar { -webkit-transform: translate(0px, 0px); transform: translate(0px, 295px); } .navbar-nav.mobile-bar { list-style: none; -ms-box-orient: horizontal; display: -webkit-box; display: -moz-box; display: -ms-flexbox; display: -moz-flex; display: -webkit-flex; display: flex; -webkit-justify-content: space-around; justify-content: space-around; -webkit-flex-flow: row wrap; flex-flow: row wrap; -webkit-align-items: stretch; align-items: stretch; margin: 0px 0px; } .navbar-nav.mobile-bar > li { -webkit-flex-grow: 1; flex-grow: 1; text-align: center; } .navbar-nav.mobile-bar > li > a > span.menu-icon { display: block; font-size: 1.8em; } .navbar-more { background-color: rgb(255, 255, 255); height: calc(100% - 69px); overflow: auto; } .navbar-more .navbar-form { border-width: 0px; } .navbar-more .navbar-nav > li > a { color: rgb(64, 64, 64); } .navbar-more > .navbar-nav > li > a > span.menu-icon { margin-left: 10px; margin-right: 10px; } @media (min-width: 768px) { .navbar { height: auto; -webkit-transform: translate(0px, 0px); transform: translate(0px, 0px); } .navbar-nav.mobile-bar { display: block; max-height: 64px; margin: 0px -.; } .navbar-nav.mobile-bar > li > a > span.menu-icon { display: none; } }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="navbar-more-overlay"></div> <nav class="navbar navbar-inverse navbar-fixed-top animate"> <div class="container navbar-more visible-xs"> <form class="navbar-form navbar-left" role="search"> <div class="form-group"> <div class="input-group"> <input type="text" class="form-control" placeholder="Search for..."> <span class="input-group-btn"> <button class="btn btn-default" type="submit">Submit</button> </span> </div> </div> </form> <ul class="nav navbar-nav"> <li> <a href="#"> <span class="menu-icon fa fa-picture-o"></span> Photos </a> </li> <li> <a href="#"> <span class="menu-icon fa fa-bell-o"></span> Reservations </a> </li> </ul> </div> <div class="container"> <div class="navbar-header hidden-xs"> <a class="navbar-brand" href="#">Brand</a> </div> <ul class="nav navbar-nav navbar-right mobile-bar"> <li> <a href="#"> <span class="menu-icon fa fa-home"></span> Home </a> </li> <li> <a href="#"> <span class="menu-icon fa fa-info"></span> <span class="hidden-xs">About the Boat</span> <span class="visible-xs">About</span> </a> </li> </li> <li> <a href="#"> <span class="menu-icon fa fa-phone"></span> <span class="hidden-xs">Contact Us</span> <span class="visible-xs">Contact</span> </a> </li> <li class="visible-xs"> <a href="#navbar-more-show"> <span class="menu-icon fa fa-bars"></span> More </a> </li> </ul> </div> </nav>

Answer 1

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

從您的描述來看，您似乎需要添加代碼來隱藏要開始的元素：

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