Angularjs渲染的 using 指令的星级评分系统示例

本文介绍Angularjs渲染的 using 指令的星级评分系统示例，分享给大家，具体如下：
我试图创建静态使用 angularjs/离子成效甚微的星级评分系统。但目前什么都不输出到屏幕上......我是我做错了吗？

service.html

 <ion-list>
  <ion-item ng-repeat="business in businessList track by $index" class="item-icon-right">
   <h2>{{business.name}}</h2> {{business.distance}} miles
   <br>
   <div star-rating rating-value="{{business.rating}}" max="rating.max"></div>
   <i class="icon ion-chevron-right icon-accessory"></i>
  </ion-item>
 </ion-list>

directives.js

angular.module('starter.directives', [])

.directive('starRating', function() {
 return {
  restrict: 'A',
  template: '<ul class="rating">' +
   '<li ng-repeat="star in stars" ng-class="star">' +
   '\u2605' +
   '</li>' +
   '</ul>',
  scope: {
   ratingValue: '=',
   max: '='
  },
  link: function(scope, elem, attrs) {
   scope.stars = [];
   for (var i = 0; i < scope.max; i++) {
    scope.stars.push({
     filled: i < scope.rating
    });
   }
  }
 }
});

services.js

.service("BusinessData", [function () {
  var businessData = [
  {
    id: 1,
    serviceId: 1,
    name: 'World Center Garage',
    distance: 0.1,
    rating: 4
  }
];

  return {
    getAllBusinesses: function () {
      return businessData;
    },

    getSelectedBusiness: function(serviceId) {
      var businessList = [];
      serviceId = parseInt(serviceId);
      for(i=0;i<businessData.length;i++) {
        if(businessData[i].serviceId === serviceId) {
          businessList.push(businessData[i]);
        }
      }
      return businessList;
    }
  }
}])

controller.js

.controller('ServiceCtrl', function($scope, ServicesData, BusinessData, $stateParams) {
 $scope.service = ServicesData.getSelectedService($stateParams.service);
 $scope.businessList = BusinessData.getSelectedBusiness($stateParams.service);
});

解决方法 1:

controller.js

.controller('ServiceCtrl', function($scope, ServicesData, BusinessData, $stateParams) {
 $scope.service = ServicesData.getSelectedService($stateParams.service);
 $scope.businessList = BusinessData.getSelectedBusiness($stateParams.service);
 $scope.ratings = {
   current: 5,
   max: 10
   };

和也修改service.html

<div star-rating rating-value="rating.current" max="rating.max"></div>
