html：其实就是根据table标签把几个实心圆div进行等边六角形的排布，并放入一个div容器中，然后利用CSS3的循环旋转的动画效果对最外层的div容器进行自转实现，当然不要忘了把div容器的外边框设置圆形弧度的。

<div class="animation_div">
        <table class="table_class">
            <tr>
                <td></td>
                <td>
                    <div class="BMI" ng-click="compriseClicked('BMI')" ng-class="{isSelected:clickUrlKey=='BMI'}">
                        <strong>BMI</strong>
                    </div>
                </td>
                <td></td>
                <td>
                    <div class="color_blind" ng-click="compriseClicked('color_blind')" ng-class="{isSelected:clickUrlKey=='color_blind'}">
                        <strong>色盲色弱</strong>
                    </div>
                </td>
                <td></td>
            </tr>
            <tr>
                <td>
                    <div class="space_div"></div>
                </td>
            </tr>
            <tr>
                <td>
                    <div class="HR" ng-click="compriseClicked('HR')" ng-class="{isSelected:clickUrlKey=='HR'}">
                        <strong>心率</strong>
                    </div>
                </td>
                <td></td>
                <td>
                    <a href="#/app/custom_made/counselor/{{clickUrlKey}}" style="text-decoration: none;
                        color: black;">
                        <div class="start_test">
                            <strong>开始测试</strong>
                        </div>
                    </a>
                </td>
                <td></td>
                <td>
                    <div class="fat_content" ng-click="compriseClicked('fat_content')" ng-class="{isSelected:clickUrlKey=='fat_content'}">
                        <strong>脂肪含量</strong>
                    </div>
                </td>
            </tr>
            <tr>
                <td>
                    <div class="space_div"></div>
                </td>
            </tr>
            <tr>
                <td></td>
                <td>
                    <div class="WHR" ng-click="compriseClicked('WHR')" ng-class="{isSelected:clickUrlKey=='WHR'}">
                        <strong>腰臀比</strong>
                    </div>
                </td>
                <td></td>
                <td>
                    <div class="safe_period" ng-click="compriseClicked('safe_period')" ng-class="{isSelected:clickUrlKey=='safe_period'}">
                        <strong>安全期</strong>
                    </div>
                </td>
                <td></td>
            </tr>
        </table>
    </div>
    
    <h3>clickUrlKey:{{clickUrlKey}}</h3>

css：因为在圆形的轨迹中有6个实心圆，分别设置了不同的类以方便自定义，所以当中实心圆的样式设置有重复的地方，还可以进行优化，在这就先不处理了

<style>

          background-color: yellow;
          border-radius: 100px;
          text-align: center;
          
          /*文字垂直居中*/
          vertical-align: middle;
          line-height: 50px;
      }
      
      .space_div {
          width: 50px;
          height: 50px;
          background-color: clear;
          border-radius: 100px;
      }
      
      .rightmenu_btn {
          height: 60px;
          float: none;
      }
      
      .rightmenu_btn button {
          margin-top: 50px;
          width: 20px;
          height: 60px;
          border: 1px solid rgb(221, 221, 221);
          border-right: 0px;
          float: right;
      }
      
      .isSelected {
          border: 1px solid red;
      }
  </style>

JS：这里的代码可以不实现，因为这跟动画的效果无关，是一个点击的响应事件

angular.module('starter.controllers', [])
    .controller('healthCtrl', function($scope, $location) {
        $scope.clickUrlKey = "BMI";
        $scope.compriseClicked = function(clickUrlKey) {
            $scope.clickUrlKey = clickUrlKey;
        };
    })

效果图如下：
