我只是想在一些div中创建简单的菜单链接？

Question

我只是想在一些动画div中创建简单的菜单链接，如果mous移动到它里面的（li）但是如果div空了它工作得很好，问题就是div disapper？

首先我想到的是我必须阻止事件传播，所以我将它添加到sum菜单中的元素（（li））但仍然面临同样的问题。

function hidemneu() {
  $('#submenu1').hide('fold', 'slow');
  $('#submenu2').hide('fold', 'slow');
  $('#submenu3').hide('fold', 'slow');
  $('#submenu4').hide('fold', 'slow');
}

$('#submenu1, #submenu2, #submenu3, #submenu4 ').on('mouseout', hidemneu);

$('#btn1').on('mouseover', function() {
  hidemneu();

  $('#submenu1').offset({

    left: $('#btn1').offset().left
  });


  $('#submenu1').show("fold");


});
$('#btn2').on('mouseover', function() {
  hidemneu();


  $('#submenu2').offset({

更改javascript的第8行似乎可以解决问题：

发件人：

 $('#submenu1, #submenu2, #submenu3, #submenu4 ').on('mouseout', hidemneu);

以

 $('#submenu1, #submenu2, #submenu3, #submenu4 ').mouseleave(hidemneu);

＆＃13;

＆＃13;

function hidemneu() {
  $('#submenu1').hide('fold', 'slow');
  $('#submenu2').hide('fold', 'slow');
  $('#submenu3').hide('fold', 'slow');
  $('#submenu4').hide('fold', 'slow');
}

$('#submenu1, #submenu2, #submenu3, #submenu4 ').mouseleave(hidemneu);

$('#btn1').on('mouseover', function() {
  hidemneu();

  $('#submenu1').offset({

    left: $('#btn1').offset().left
  });


  $('#submenu1').show("fold");


});
$('#btn2').on('mouseover', function() {
  hidemneu();


  $('#submenu2').offset({

    left: $('#btn2').offset().left
  });


  $('#submenu2').show("fold");


});

$('#btn3').on('mouseover', function() {

  hidemneu();

  $('#submenu3').offset({

    left: $('#btn3').offset().left
  });


  $('#submenu3').show("fold");


});


$('#btn4').on('mouseover', function() {

  hidemneu();

  $('#submenu4').offset({

    left: $('#btn4').offset().left
  });


  $('#submenu4').show("fold");


});


$("a").on('mouseover', function(event) {

  event.stopPropagation();

});

$("li").on('mouseover', function(event) {

  event.stopPropagation();

});


$("ul").on('mouseover', function(event) {

  event.stopPropagation();

});
