我有一个指令,它从2个单独的$ http调用中获取数据并填充2个不同的ng-repeat。
为了减少服务器调用,我只是在点击第一个ng-repeat列表的某个元素时才进行第二次调用。
所以,现在我的指令默认进行2次调用,你可以在这里看到:
var app = angular.module('myApp');
app.directive('release', ['musicInfoService', 'dataService',
function(musicInfoService, dataService) {
return {
restrict: 'E',
scope: {
release: '=',
artist: '='
},
template: '<div class="release">' +
'<div class="wrapper"><img class="img-responsive" ng-src="{{imageSrc}}"/><div id="text" ng-click="VersionController($scope, dataService)"></div></div>{{release.title | characters:45}}' +
'</div>',
replace: false,
link: function(scope, elem, attr) {
var defaultImage = 'img/record-default.png';
scope.imageSrc = defaultImage;
musicInfoService.getAlbumInfo(scope.artist.name, scope.release.title)
.success(function(data) {
if (data.error) return;
var image = data.album.image[2],
imageUrl = defaultImage;
if (image['#text'] !== '') {
imageUrl = image['#text'];
}
scope.imageSrc = imageUrl;
});
var defaultFormat = scope.release.format;
musicInfoService.getReleaseVersions(scope.release.id)
.success(function(data) {
if (data.error) return;
var format = data.versions,
formats = scope.release.format;
if (format !== '') {
formats = format;
}
scope.defaultFormat = formats;
dataService.setItems(scope.release.id.toString(), scope.defaultFormat);
})
.error(function($scope) {
scope.defaultFormat = false;
dataService.setItems("basic", scope.defaultFormat);
});
}
};
}
]);
app.factory('dataService', [function($scope){
var _items= {};
return {
setItems:function(key, value){
_items[key] = value;
},
getItems:function(key){
return _items[key] ? _items[key] : _items["basic"];
}
};
}]);
结果存储在Factory中,并从Controller调用,如下所示:
function VersionController($scope, dataService) {
$scope.versions = dataService.getItems($scope.release.id.toString());
console.log($scope.versions);
}
然后,我可以将第二个调用作为函数放在指令之外,并将其称为ng-click =“CallFunctionName”吗?我已经尝试过但它不起作用,所以也许我错过了一些东西。或者比这更复杂?
