無法停止傳播上滑動效果的菜單

Question

我在一個帶有基本菜單模塊的joomla網站上做了一個菜單。我用滑動效果來設置動畫效果，現在沒問題，除了調整窗口大小的一件事情：如果在使用菜單時調整窗口大小，效果會重複多次。我試圖阻止點擊事件的傳播，但我不能。即使e.stopPropagation（）

在那裏，你可以試試我的菜單：https://jsfiddle.net/fgctp81v/

和TH JS代碼如下：

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

您必須刪除任何現有的click事件與off。

$('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 
 
    }
