单击时继续在菜单中显示子项

问题描述 投票:1回答:1

这是我在这个网站上的第一个问题。一直在这里搜索多次,发现我需要的几乎所有答案。

我正在使用underscores.me ==> test.davidsfonds-zele.be在wordpress网站上工作

在左侧,您可以找到一个垂直菜单,可以打开该菜单以单击子项。

当您单击并转到所属页面时,子项目会突出显示,但您无法看到它,因为菜单不再打开。

有办法让它打开吗?

菜单是在Wordpress的管理面板中构建的,因为其他管理员(没有任何网络知识)也允许更改菜单。

我尝试了很多东西,但都没有成功。如果您有完整的其他方式,请随时学习我。我认为我使用的这段代码是很长的方式...我使用以下方法来获得我现在拥有的东西:

                        element.siblings('li').children('ul').slideUp();
			element.siblings('li').removeClass('open');
			element.siblings('li').find('li').removeClass('open');
			element.siblings('li').find('ul').slideUp();
		}
	});

	$('#cssmenu>ul>li.has-sub>a').append('<span class="holder"></span>');

	(function getColor() {
		var r, g, b;
		var textColor = $('#cssmenu').css('color');
		textColor = textColor.slice(4);

		textColor = textColor.slice(textColor.indexOf(' ') + 1);
		g = textColor.slice(0, textColor.indexOf(','));
		textColor = textColor.slice(textColor.indexOf(' ') + 1);
		b = textColor.slice(0, textColor.indexOf(')'));
		var l = rgbToHsl(r, g, b);
		if (l > 0.7) {
			$('#cssmenu>ul>li>a').css('text-shadow', '0 1px 1px rgba(0, 0, 0, .35)');
			$('#cssmenu>ul>li>a>span').css('border-color', 'rgba(0, 0, 0, .35)');

		else

			$('#cssmenu>ul>li>a>span').css('border-color', 'rgba(255, 255, 255, .35)');
		}
	})();

	function rgbToHsl(r, g, b) {
	    r /= 255, g /= 255, b /= 255;
	    var max = Math.max(r, g, b), min = Math.min(r, g, b);
	    var h, s, l = (max + min) / 2;

	    if(max == min){
	        h = s = 0;

	    else {
	        var d = max - min;
	        s = l > 0.5 ? d / (2 - max - min) : d / (max + min);
	        switch(max){
	            case r: h = (g - b) / d + (g < b ? 6 : 0); break;
	            case g: h = (b - r) / d + 2; break;
	            case b: h = (r - g) / d + 4; break;
	        }
	        h /= 6;
	    }
	    return l;
	}
});

我建议你使用WordPress导航菜单中提供的CSS类。在您的情况下,您可以使用JavaScript中的函数在您的手风琴菜单中打开带有.current-menu-parent.current-menu-ancestor的元素。有点像下面的代码,虽然我还没有测试过(因为我不能):

$('#cssmenu li.has-sub.current-menu-parent').addClass('open').children('ul').slideDown();

如果您将其放入文档准备就绪,那么应该显示特定的菜单。
