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>
