	<body>
		<ul>
  <li>Tab One</li>
  <li>Tab Two</li>
  <li>Tab Three</li>
  <li class=\"slider\"></li>
</ul> 
	</body>
</html>

 

css代码如下:

ul {
  font-size: 0;
  position: relative;
  padding: 0;
  width: 480px;
  margin: 40px auto;
  user-select: none;
}
 
li {
  display: inline-block;
  width: 160px;
  height: 60px;
  background: #E95546;
  font-size: 16px;
  text-align: center;
  line-height: 60px;
  color: #fff;
  text-transform: uppercase;
  position: relative;
  overflow: hidden;
  cursor: pointer;
}     
.slider {
  display: block;
  position: absolute;
  bottom: 0;
  left: 0;
  height: 4px;
  background: #4FC2E5;
  transition: all 0.5s;
}     
.ripple {
  width: 0;
  height: 0;
  border-radius: 50%;
  background: rgba(255, 255, 255, 0.4);
  -webkit-transform: scale(0);
  -ms-transform: scale(0);
  transform: scale(0);
  position: absolute;
  opacity: 1;
}
 
.rippleEffect {
  -webkit-animation: rippleDrop .4s linear;
  animation: rippleDrop .4s linear;
}
 
@-webkit-key s 
  rippleDrop {  100% {
   -webkit-transform: scale(2);
   transform: scale(2);
   opacity: 0;
  }
}
@key s 
  rippleDrop {  100% {
   -webkit-transform: scale(2);
   transform: scale(2);
   opacity: 0;
  }
}   

 

js代码如下:

$(\"ul li\").click(function(e) {
 
  if ($(this).hasClass(\'slider\')) {
    return;
  }
 
  var whatTab = $(this).index();
 
  var howFar = 160 * whatTab;
 
  $(\".slider\").css({
    left: howFar + \"px\"
  });
 
  $(\".ripple\").remove();
 
  var posX = $(this).offset().left,
      posY = $(this).offset().top,
      buttonWidth = $(this).width(),
      buttonHeight = $(this).height();
 
  $(this).prepend(\"<span class=\'ripple\'></span>\");
 
  if (buttonWidth >= buttonHeight) {
    buttonHeight = buttonWidth;
  } else {
    buttonWidth = buttonHeight;
  }
 
  var x = e.pageX - posX - buttonWidth / 2;
  var y = e.pageY - posY - buttonHeight / 2;
 
  $(\".ripple\").css({
    width: buttonWidth,
    height: buttonHeight,
    top: y + \'px\',
    left: x + \'px\'
  }).addClass(\"rippleEffect\");
   
});
