基于jQuery数据属性的鼠标滚轮和上下弹头导航

jquery javascript

我有一个WordPress页面,有一个带分页的滑块和一个页脚div。

现在,分页只包含类 pagination & active ,并且每个分页选项都具有唯一性 data-page value .

我可以知道吗 如何制作鼠标滚轮、kboard up/down&page up/down(向上/向下翻页)按钮可在分页中导航 没有任何外部插件。而且,当分页完成时, 如果用户再次按下,将显示页脚,并且没有用于分页的活动类 .

像这样的例子 https://causeeffect.asia/services/

无论如何,我不能100%复制,因为滑块来自WordPress插件,但下面的代码基本上就是它的样子。

window.slide = new SlideNav();

body, html {
	margin: 0;
	padding: 0;
}

.section {
	min-height: 800px;
	position: relative;
	text-align: center;
	font-family: sans-serif, arial;
	margin: 0;
}

h1, p {
	margin: 0;
	font-family: sans-serif, arial;
	font-weight: bold;
}

.text-wr {
	position: absolute;
	top: 50%;
	left: 50%;
	-webkit-transform: translate(-50%, -50%);
	-moz-transform: translate(-50%, -50%);
	-o-transform: translate(-50%, -50%);
	-ms-transform: translate(-50%, -50%);
	transform: translate(-50%, -50%);
}

您可以使用jQuery keydown事件进行up/down/pageup/pagedown事件,也可以使用鼠标滚动。检查以下键盘键代码,如:

document.onkeydown = function(e) {
    if (e.keyCode == 38 || e.keyCode == 33 ) { 
        //do your code here for slide next
    } else if(e.keyCode == 40 || e.keyCode == 34) { 
       //do your code for slide pervious
    }
}

对于鼠标滚动,您可以使用以下代码: How can I determine the direction of a jQuery scroll event?

var lastScrollTop = 0;
$(window).scroll(function(event){
   var st = $(this).scrollTop();
   if (st > lastScrollTop){
       // downscroll code
   } else {
      // upscroll code
   }
   lastScrollTop = st;
});

希望对你有帮助。
