如何在MouseOver上动画CSS动画汉堡包图标 [英] How To Animate CSS Animated Hamburger Icon On MouseOver

问题描述

我在 http://elijahmanor.com/上有一个动画CSS汉堡包图标css-animated-hamburger-icon / ，我想要使用它，但我想通过悬停来查看设置前（X），而不是悬停时将其设置为3行的默认样式。但我不能这样做，即使我使用悬停功能。

悬停事件称为 mouseover 。



事件名称是传统的 HTML DOM事件，只是没有
打开前缀。例如，使用 mouseover 而不是 onmouseover 。

  document.querySelector（＃nav-toggle）.addEventListener（mouseover，function（）{this.classList.toggle（active）;}） ;  

＃nav-toggle {position：absolute;剩下：50％;顶部：50％; }＃nav-toggle {cursor：pointer; padding：10px 35px 16px 0px; }＃nav-toggle span，＃nav-toggle span：before，＃nav-toggle span：after {cursor：pointer; border-radius：1px; height：5px;宽度：35px;背景：黑色;位置：绝对;显示：块; content：'';}＃nav-toggle span：before {top：-10px; }＃nav-toggle span：after {bottom：-10px;}＃nav-toggle span，＃nav-toggle span：before，＃nav-toggle span：after {transition：all 500ms ease-in-out;}＃nav -toggle.active span {background-color：transparent;}＃nav-toggle.active span：before，＃nav-toggle.active span：after {top：0;}＃nav-toggle.active span：before {transform： rotate（45deg）;}＃nav-toggle.active span：after {transform：rotate（-45deg）;}

 < a id =nav-togglehref =＃>< span>< / span>< / a>  

I've got an animated CSS Hamburger icon at http://elijahmanor.com/css-animated-hamburger-icon/ and I wanna need to use it but I want to use it via hover to view set ex(x) and when not hover set it to default style that 3 lines. But I cannot do that even I used hover function.

document.querySelector("#nav-toggle")
  .addEventListener("click", function() {
    this.classList.toggle("active");
  });

#nav-toggle {
  position: absolute;
  left: 50%;
  top: 50%;
}

#nav-toggle {
  cursor: pointer;
  padding: 10px 35px 16px 0px;
}

#nav-toggle span,
#nav-toggle span:before,
#nav-toggle span:after {
  cursor: pointer;
  border-radius: 1px;
  height: 5px;
  width: 35px;
  background: black;
  position: absolute;
  display: block;
  content: '';
}

#nav-toggle span:before {
  top: -10px;
}

#nav-toggle span:after {
  bottom: -10px;
}

#nav-toggle span,
#nav-toggle span:before,
#nav-toggle span:after {
  transition: all 500ms ease-in-out;
}

#nav-toggle.active span {
  background-color: transparent;
}

#nav-toggle.active span:before,
#nav-toggle.active span:after {
  top: 0;
}

#nav-toggle.active span:before {
  transform: rotate(45deg);
}

#nav-toggle.active span:after {
  transform: rotate(-45deg);
}

<a id="nav-toggle" href="#"><span></span></a>

解决方案

The hover event is called mouseover.

The events name are the classic HTML DOM Events, just without the on prefix. For example, use mouseover instead of onmouseover.

document.querySelector( "#nav-toggle" )
  .addEventListener( "mouseover", function() {
    this.classList.toggle( "active" );
  });

#nav-toggle { position: absolute; left: 50%; top: 50%; }

#nav-toggle { cursor: pointer; padding: 10px 35px 16px 0px; }
#nav-toggle span, #nav-toggle span:before, #nav-toggle span:after {
  cursor: pointer;
  border-radius: 1px;
  height: 5px;
  width: 35px;
  background: black;
  position: absolute;
  display: block;
  content: '';
}
#nav-toggle span:before {
  top: -10px; 
}
#nav-toggle span:after {
  bottom: -10px;
}

#nav-toggle span, #nav-toggle span:before, #nav-toggle span:after {
  transition: all 500ms ease-in-out;
}
#nav-toggle.active span {
  background-color: transparent;
}
#nav-toggle.active span:before, #nav-toggle.active span:after {
  top: 0;
}
#nav-toggle.active span:before {
  transform: rotate(45deg);
}
#nav-toggle.active span:after {
  transform: rotate(-45deg);
}

<a id="nav-toggle" href="#"><span></span></a>
