跟随光标圆形文本旋转

今天给大家带来的是光标变成圆形字符串环绕
不多说先上效果图
在这里插入图片描述
原理呢,也很简单
就是先把文本

<h2>大威天龙 - 世尊地藏 - 般若诸佛 - 般若巴嘛哄 -</h2>

然后使用js将文本处理成每个字符一个span,并且让他们旋转

	let text = document.querySelector('h2')
	
	text.innerHTML = text.textContent.replace(/\S/g, '<span>$&</span>')
	let element = document.querySelectorAll('span')
	for (let i = 0; i < element.length; i++) {
	  element[i].style.transform = 'rotate(' + i * 17 + 'deg)'
	}

然后添加鼠标移动事件,让这个文本跟随鼠标移动

document.addEventListener('mousemove', e => {
      text.style.left = e.pageX + 'px'
      text.style.top = e.pageY + 'px'
      text.style.transform = `rotate(${e.pageX / 2}deg)
      rotate(${e.pageY / 2}deg)`
    })

然后给每一个文本添加偏移

 transform-origin: 0 120px;

这样就成功了
遵循开源精神,你有我有大家有
