Question

如果你看看KIOSK WEBSITE HERE他们在javascript中有'WE ARE OPEN'循环类型（我知道该怎么做）但我不知道的是如何在滚动时实现这一点。当向上或向下滚动时文本如何移动。你如何在HTML / CSS / JS中获得它？

查看我在here https://codepen.io/noel_emmanuel/pen/WJxRZW

上工作的代码

HTML：

<!--just a container used to position in the page-->
<div class="container">
  <!--the holders/targets for the text, reuse as desired-->
  <div class="circTxt" id="test"></div>
</div>

<!--I told you it was simple! :)-->

CSS：

body {
  background: #111;
}

.container {
  /*centers in the container*/
  text-align: center;
}

div.circTxt {
  /*allows for centering*/
  display: inline-block;
  /*adjust as needed*/
  margin-bottom: 128px;
  color: whitesmoke;
}

JS：

function circularText(txt, radius, classIndex) {
  txt = txt.split(""),
    classIndex = document.getElementsByClassName("circTxt")[classIndex];

  var deg = 360 / txt.length,
    origin = 0;

  txt.forEach((ea) => {
    ea = `<p style='height:${radius}px;position:absolute;transform:rotate(${origin}deg);transform-origin:0 100%'>${ea}</p>`;
    classIndex.innerHTML += ea;
    origin += deg;
  });
}

circularText("WE ARE OPEN", 100, 0);

打开建议。

您可以在滚动事件上旋转它。这只是根据您滚动页面顶部的距离旋转div。

我在文字中添加了height和width，并将其定位fixed以查看效果。

function circularText(txt, radius, classIndex) {
  txt = txt.split(""),
    classIndex = document.getElementsByClassName("circTxt")[classIndex];

  var deg = 360 / txt.length,
    origin = 0;

  txt.forEach((ea) => {
    ea = `<p style='height:${radius}px;position:absolute;transform:rotate(${origin}deg);transform-origin:0 100%'>${ea}</p>`;
    classIndex.innerHTML += ea;
    origin += deg;
  });
}

circularText("WE ARE OPEN", 100, 0);


$(document).ready(function(){
	$(window).scroll(function(e){
		rotateText();
	});

	function rotateText(){
		var scrolled = $(window).scrollTop();
		$('div.circTxt').css('transform','rotate('+scrolled+'deg)');
	}
});

body {
  background: #111;
}

.container {
  /*centers in the container*/
  text-align: center;
  
  height: 4000px;
}

div.circTxt {
  /*allows for centering*/
  display: inline-block;
  /*adjust as needed*/
  margin-bottom: 128px;
  color: whitesmoke;
  
  position: fixed;
  height: 200px;
  width: 200px;
  transform-origin: 0% 59%;
}
