在指令中发出获取请求 - Ionic Framework

Question

我正在尝试调整 angular-pickdate (https://github.com/jimibi/angular-pickadate) 模块以满足我的需要，但由于无法发出 GET 请求，我已经停滞不前了我习惯的方式。

我的代码是： ...

.directive('pickadate', ['$locale', 'pickadateUtils', 'pickadateI18n', 'dateFilter', function($locale, dateUtils, i18n, dateFilter) {


  return {
    require: 'ngModel',
    scope: {
      date: '=ngModel',
      defaultDate: '=',
      minDate: '=',
      maxDate: '=',
      disabledDates: '='
    },
    template:
      ...,

    link: function(scope, element, attrs, ngModel,$http)  {

      var minDate       = scope.minDate && dateUtils.stringToDate(scope.minDate),
          maxDate       = scope.maxDate && dateUtils.stringToDate(scope.maxDate),
          disabledDates = scope.disabledDates || [],
          currentDate   = (scope.defaultDate && dateUtils.stringToDate(scope.defaultDate)) || new Date();

      scope.dayNames    = $locale.DATETIME_FORMATS['SHORTDAY'];
      scope.currentDate = currentDate;
      scope.t           = i18n.t;
      scope.render = function(initialDate,$http) {
        initialDate = new Date(initialDate.getFullYear(), initialDate.getMonth(), 1, 3);

          $http({url: 'myplace/script_lotacoes.php', method: 'GET'}).success(function(){alert("hheheh");}).error(function(){alert("oops");});

...

这段代码给我的错误是：

  TypeError: undefined is not a function
at Scope.angular.module.provider.factory.directive.link.scope.render (angular-pickadate.js:122)
at angular.module.provider.factory.directive.link.ngModel.$render (angular-pickadate.js:191)

at done (ionic.bundle.js:17942)
at completeRequest (ionic.bundle.js:18132)
at XMLHttpRequest.requestLoaded (ionic.bundle.js:18073)

此错误与 $http 请求有关。

有谁知道我为什么会收到此错误，我该如何解决？提前致谢

Answer 1

在指令中注入$http服务：

.directive('pickadate', ['$http', '$locale', 'pickadateUtils', 'pickadateI18n', 'dateFilter', function($http, $locale, dateUtils, i18n, dateFilter) {

Answer 2

您正在将 $http 注入您的 link 函数以及您的 scope.render 函数。删除这两次注入尝试 - 您只需要将其注入您的指令即可。

.directive('pickadate', ['$locale', 'pickadateUtils', 'pickadateI18n', 'dateFilter', '$http', function($locale, dateUtils, i18n, dateFilter, $http) {
