实现过程

CSS

选择 按钮

.selector button {

  position: relative;

  width: 100%;

  height: 100%;

  padding: 10px;

  background: #428bca;

  border-radius: 50%;

  border: 0;

  color: white;

  font-size: 20px;

  cursor: pointer;

  box-shadow: 0 3px 3px rgba(0, 0, 0, 0.1);

  transition: all .1s;

}

cursor 属性规定要显示的光标的类型（pointer 光标呈现为指示链接的指针）

 选择 标签

.selector li {

  position: absolute;

  width: 0;

  height: 100%;

  margin: 0 50%;

  -webkit-transform: rotate(-360deg);

  transition: all 0.8s ease-in-out;

}

transition-property 属性规定应用过渡效果的 CSS 属性的名称

　　all 所有属性都将获得过渡效果

　　0.8s 属性过渡时间

　　ease-in-out 规定以慢速开始和结束的过渡效果

鼠标触碰按钮时变化颜色

.selector button:hover {

  background: #3071a9;

}

子标签初始化旋转效果

.selector li input + label {

  position: absolute;

  left: 50%;

  bottom: 100%;

  width: 0;

  height: 0;

  line-height: 1px;

  margin-left: 0;

  background: #fff;

  border-radius: 50%;

  text-align: center;

  font-size: 1px;

  overflow: hidden;

  cursor: pointer;

  box-shadow: none;

  transition: all 0.8s ease-in-out, color 0.1s, background 0.1s;

}

鼠标触碰子标签时显示的颜色

.selector li input + label:hover {

  background: #f0f0f0;

}

子标签的颜色

.selector li input:checked + label:hover {

  background: #449d44;

}

子标签文字的颜色

.selector li input:checked + label {

  background: #5cb85c;

  color: white;

}

JS

设置标签旋转度数

var angleStart = -360;

　　

多选菜单旋转动画

function rotate(li,d) {

    $({d:angleStart}).animate({d:d}, {

        step: function(now) {

            $(li)

               .css({ transform: 'rotate('+now+'deg)' })

               .find('label')

                  .css({ transform: 'rotate('+(-now)+'deg)' });

        }, duration: 0

    });

}

duration ：返回动画当前时间长度

显示/影藏多选菜单

function toggleOptions(s) {

    $(s).toggleClass('open');

    var li = $(s).find('li');

    var deg = $(s).hasClass('half') ? 180/(li.length-1) : 360/li.length;

    for(var i=0; i<li.length; i++) {

        var d = $(s).hasClass('half') ? (i*deg)-90 : i*deg;

        $(s).hasClass('open') ? rotate(li[i],d) : rotate(li[i],angleStart);

    }

}

find() 方法获得当前元素集合中每个元素的后代（获得全部的li标签）

hasClass() 方法检查被选元素是否包含指定的 class

　　　(找到了子标签旋转出来，没找到子标签旋转回去)

点击按钮调用toggleOptions(s)函数

$('.selector button').click(function(e) {

    toggleOptions($(this).parent());

});

parent() 获得当前匹配元素集合中每个元素　(获得元素全部标签)

设置动作时间

setTimeout(function() { toggleOptions('.selector'); }, 100);
