javascript - 点击外部导航关闭

标签 javascript jquery html css

我有下面的代码，它工作正常，但是我需要它在点击导航外部时关闭导航(所以不是按钮)

我试过了，但是不行

$("body").click(function (e) {
         $('#navwrapper').removeClass('is-visible');
    });

任何帮助将不胜感激

非常感谢

最佳答案

代码运行良好，只有两个小的调整使其完全运行:

  1. 将 click 事件监听器附加到 document 而不是 body。

    $(document).on("click", function() {
   $('#navwrapper').removeClass('is-visible');
});

    现在你在body中只有一个元素(#cd-nav)，它有position:absolute;这意味着它从文档的常规流程中取出，“清空”body，它的高度将为 0，您将永远无法点击它。因此，将事件处理程序附加到 document 而不是 body。

    注意:这在实际页面上不是必需的，因为我猜你会有更多的内容会占据窗口，但它适用于你在问题中发布的演示。

  2. 当打开菜单的元素被点击时停止传播事件。

    $('.cd-nav-trigger').on('click', function(e){
    e.preventDefault();
    e.stopPropagation();

    点击事件会冒泡到 body 和 document，所以即使触发器显示它，事件也会冒泡和 click 文档的事件处理程序将隐藏它。你想停止传播以避免这种情况。

您可以看到它在此代码中的工作(通过查找下面的注释 //AM 来找到更改):

var offset = 0;

var navigationContainer = $('#cd-nav'),
    mainNavigation = navigationContainer.find('#cd-main-nav ul');


checkMenu();

// AM: add the listener to the document
$(document).on("click", function() {
  $('#navwrapper').removeClass('is-visible')
});

$(window).scroll(function(){
  checkMenu();
});

$('.cd-nav-trigger').click(function(){
  $('.content').toggleClass('static');
})

$('.cd-nav-trigger').on('click', function(e){
  // AM: prevent the default behavior
  e.preventDefault();
  e.stopPropagation();
  $(this).toggleClass('menu-is-open');
  mainNavigation.off('webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend').toggleClass('is-visible');
});

function checkMenu() {
  if( $(window).scrollTop() > offset && !navigationContainer.hasClass('is-fixed')) {
    navigationContainer.addClass('is-fixed').find('.cd-nav-trigger').one('webkitAnimationEnd oanimationend msAnimationEnd animationend', function(){
      mainNavigation.addClass('has-transitions');
    });
  } else if ($(window).scrollTop() <= offset) {
    //check if the menu is open when scrolling up
    if( mainNavigation.hasClass('is-visible')  && !$('html').hasClass('no-csstransitions') ) {
      //close the menu with animation
      mainNavigation.addClass('is-hidden').one('webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend', function(){
        //wait for the menu to be closed and do the rest
        mainNavigation.removeClass('is-visible is-hidden has-transitions');
        navigationContainer.removeClass('is-fixed');
        $('.cd-nav-trigger').removeClass('menu-is-open');
      });
      //check if the menu is open when scrolling up - fallback if transitions are not supported
    } else if( mainNavigation.hasClass('is-visible')  && $('html').hasClass('no-csstransitions') ) {
      mainNavigation.removeClass('is-visible has-transitions');
      navigationContainer.removeClass('is-fixed');
      $('.cd-nav-trigger').removeClass('menu-is-open');

      //scrolling up with menu closed
