Question

标题显示当我在按钮的下拉菜单外点击时，我的脚本不想工作

＆＃13;

$(document).ready(function() {
  $(".openmenu").click(function() {
    var X = $(this).attr('id');
    if (X == 1) {
      $(".submenu").hide();
      $(this).attr('id', '0');
    } else {
      $(".submenu").show();
      $(this).attr('id', '1');
    }
  });
  $(".submenu").mouseup(function() {
    return false
  });
  $(".openmenu").mouseup(function() {
    return false
  });
  $(document).mouseup(function() {
    $(".submenu").hide();
    $(".openmenu").attr('id', '');
  });
});

$(document).ready(function() {
  myInit()
})


$(document).ready(function() {
  myInit()
})

function myInit() {
  $('.openmenu').click(function() {
    $('.openmenu').removeClass('active')
    $(this).addClass('active')
  })
}

当我点击登录按钮时，它会变为活动课程，这会更改按钮的背景，这很好但是当我点击外面时它不想工作，我希望活动课程能够被删除，css颜色返回。我做错了什么？

Answer 1

您的mouseup事件只是添加：

.removeClass("active");

到

$(".openmenu").attr('id', '');

像这样：

$(document).mouseup(function(){
   $(".submenu").hide();
   $(".openmenu").attr('id', '').removeClass("active"); <-----
});

将来，请不要将jquery库复制到小提琴中，只需从侧面菜单中选择jquery

javascript drop menu在点击时处于活动状态，在外部点击时无效
