ionic+AngularJs实现获取验证码倒计时按钮

angular.module('winwin').directive('timerbutton', function($timeout, $interval){
  return {
    restrict: 'AE',
    scope: {
      showTimer: '=',
      timeout: '='
    },
    link: function(scope, element, attrs){
      scope.timer = false;
      scope.timeout = 60000;
      scope.timerCount = scope.timeout / 1000;
      scope.text = "获取验证码";

      scope.OnClick= function(){
        scope.showTimer = true;
        scope.timer = true;
        scope.text = "秒后重新获取";
        var counter = $interval(function(){
          scope.timerCount = scope.timerCount - 1;
        }, 1000);

        $timeout(function(){
          scope.text = "获取验证码";
          scope.timer = false;
          $interval.cancel(counter);
          scope.showTimer = false;
          scope.timerCount = scope.timeout / 1000;
        }, scope.timeout);
      }
    },
    template: '{{ timerCount }}{{text}}'
  };
});
