添加/删除类以获取要显示的菜单

时间：2018-05-24 14:31:30

标签： javascript jquery css

我之前开始编写导航菜单的移动版本。我不得不重新修改#serviceNav以使其在移动环境中工作。这样做时我改变了我的javascript：

/*$('#serviceClick').click( function () {
      $('#serviceNav').addClass('activeSol');
});*/
$('[data-pop-close]').on('click', function(e)  {
    //var targeted_pop = $(this).attr('data-pop-close');
    $('#serviceNav').removeClass('active');
    $('body').css('overflow', 'auto');
    e.preventDefault();
});

对此：

$('#serviceClick').click(function() {
    var relative = $(this);
    if (!relative.hasClass('activeSol')) {

$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
        relative.addClass('activeSol').next('#serviceNav').slideDown();
        //$('.infoTitles:before').addClass('opened');
    } else {
        relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
    }
    return false;
});

我之前没有使用我的javascript代码的问题是，现在我的#serviceNav的桌面媒体查询版本没有显示，但是它确实在移动设置中显示和运行。此菜单的触发器是名为“Solutions”的菜单项。您可以看到，在640px以上的媒体查询中没有任何反应，但640px或更少，它应用了fadeDown功能。

有谁知道为什么这不适用于更大版本的媒体查询？

Here is a jsfiddle

完整代码：

$('#mobile-button').on('click', function () {
		$('#nav-pop').addClass('active');
		$('html').addClass('is-navOpen');
	});
  /*$('#serviceClick').click( function () {
        $('#serviceNav').addClass('activeSol');
	});*/
$('#serviceClick').click(function() {
		var relative = $(this);
		if (!relative.hasClass('activeSol')) {
			$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
			relative.addClass('activeSol').next('#serviceNav').slideDown();
		} else {
			relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
		}
		return false;
	});

这里有很多事情，坦率地说，很难破译，但我认为＆＃34;什么都没发生＆＃34;是相对的。在dev控制台中检查元素时，您可以看到正在正确添加Javascript样式。所以有些事情正在发生，它只是在屏幕上发生，因为你已经告诉了它。我认为这里的罪魁祸首是，#serviceNav元素的＆gt; 640px定位保持在top: -40vh;那很多。删除此值时，按钮显示如下：

注意：您必须更改其他一些内容，因为它会在页面加载时显示。但是你明白了这个想法
