Javascript隐藏和显示div

Question

下面的代码是我的 CSS 文件。我在这里要做的是在我没有选择导航按钮<a href="#navbar-more-show"> 时隐藏<div class="container navbar-more visible-xs">。但是当我选择导航按钮时，会出现容器导航栏。这里的问题是我不确定如何默认隐藏 div 类，它一直出现在我的页面上，我希望它在我单击导航按钮时出现。

    $(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;

.navbar {

  max-height: 300px;
  -webkit-transform: translate(0px, calc(-100% + 69px));
  transform: translate(0px, calc(-100% + 595px));
}
.navbar .container:not(.navbar-more) {

.navbar-more-overlay {

Answer 1

您可以使用以下这些方法

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

Answer 2

从您的描述看来，您似乎需要添加代码来隐藏要开始的元素：

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