无法在具有向上滑动效果的菜单上停止传播

Question

我在一个 joomla 网站上制作了一个带有基本菜单模块的菜单。我用上滑效果对其进行动画处理，现在没关系，除了调整窗口大小的一件事：如果我在使用菜单时调整窗口大小，效果会重复很多次。我试图阻止点击事件的传播，但我不能。即使使用 e.stopPropagation()

在那里你可以试试我的菜单：https://jsfiddle.net/fgctp81v/

JS 代码如下：

winWidth = $( window ).width();

    if( winWidth < 1007 ){

        $('li.deeper > span.deploylist').click(function(e){
            e.preventDefault();
            menuClicked = $(this).next('a');
            if(  menuClicked.parents('li.active-menu').length ){ 
                if( menuClicked.hasClass("clicked") ){
                    menuClicked.removeClass('clicked').next('ul').slideUp(200);
                }
                else{
                    menuClicked.addClass('clicked').siblings('ul').slideDown(400);
                }
            }
            else{
                menuClicked.addClass('clicked').parents('li.parent').addClass("active-menu");
                menuClicked.siblings('ul').slideDown(400);

            }       
            winWidth = $( window ).width();     
        });
    }



Any idea ? Thank you

您必须使用off 删除任何现有的click 事件。

$('li.deeper > span.deploylist').off('click').on('click', function(e) {
   // do your stuff
}

updated fiddle

$(document).ready(function() {
  responsiveMenu();
  $(window).resize(function() {
    responsiveMenu();
  });
});

function responsiveMenu() {
  winWidth = $(window).width();

  if (winWidth < 1007) {

    $('li.deeper > span.deploylist').off('click').on('click', function(e) {
      e.preventDefault();
      menuClicked = $(this).next('a');
      if (menuClicked.parents('li.active-menu').length) {
        if (menuClicked.hasClass("clicked")) {
          menuClicked.removeClass('clicked').next('ul').slideUp(200);
        } else {
          menuClicked.addClass('clicked').siblings('ul').slideDown(400);
        }
      } else {
        menuClicked.addClass('clicked').parents('li.parent').addClass("active-menu");
        menuClicked.siblings('ul').slideDown(400);

      }
      winWidth = $(window).width();
    });
  } else {
    //do nothing now
  }
}
