使用angular指令写一个确认弹窗（移动端）

先看效果：

App.directive('confirmModel', function () {
    return {
        template: '<div class="confirm-model">\n' +
            '        <div class="up-panel">{{ title }}</div>\n' +
            '        <div class="down-panel">\n' +
            '            <div ng-click="cancel()" class="cancel">{{ valueCancel }}</div>\n' +
            '            <div ng-click="ensure()" class="ensure">{{ valueEnsure }}</div>\n' +
            '        </div>\n' +
            '    </div>'+
            '    <div class="confirm-mask"></div>',
        scope: {
            title:'@',
            valueEnsure:'@',
            valueCancel:'@',
            onCancel:'=',
            onEnsure:'=',
        },
        controller: ["$scope", function ($scope) {
           $scope.ensure=function () {
               $scope.onEnsure();
           }
           $scope.cancel=function () {
               $scope.onCancel()
           }

        }],
        link: function (scope, elem, attrs) {

        }
    };
});

HTML部分：

<div confirm-model ng-show="confirmDisplay" on-cancel="courseCancel" title="这里填写title？"  value-cancel="取消" value-ensure="购买" on-ensure="courseEnsure"></div>

JS部分：

$scope.courseEnsure=function () {
          
 }

文档：

最后附赠css

.confirm-mask {
  background-color: rgba(0, 0, 0, 0.58);
  width: 100vw;
  height: 100vh;
  position: fixed;
  left: 0;
  top: 0;
  z-index: 99999;
}

.confirm-model {
  height: 3.15rem;
  width: 6.35rem;
  background-color: #ffffff;
  border-radius: .2rem;
  position: fixed;
  margin: auto;
  left: 0;
  right: 0;
  bottom: 0;
  top: 0;
  z-index: 999999;
  padding: .5rem .7rem;
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;

  .up-panel {
    font-size: .34rem;
    color: #666666;
    line-height: .4rem;
  }

  .down-panel {
    display: flex;
    flex-wrap: nowrap;
    align-items: center;
    justify-content: space-around;
    margin-top: .3rem;

    div {
      width: 2.2rem;
      height: .9rem;
      text-align: center;
      line-height: .9rem;
      border-radius: 1rem;
      font-size: .3rem;
    }

    .ensure {
      background-color: #44c08c;
      color: #ffffff;
    }

    .cancel {
      background-color: #eaf2ef;
      color: #44c08c;
    }
  }
}

rem换算比率：1rem=100px；
