我试图在我的api中构建一些逻辑,因此它将排除在字段中具有URL的对象" image"返回4xx,5xx或超过4000ms的时间。
下面的代码并不是很有用 - 因为它仍然允许404和空白图像。
有人可以建议如何解决这个问题吗?

json的例子:{id:242,image:" www.image.com/1.jpg" ;, name:" blah blah"}
.controller('CardsCtrl', ['$scope', '$http', '$state', '$q', '$ionicLoading', '$ionicModal', 'TDCardDelegate', 'cardsApi', '$http', '$timeout', '$element',

var canceler = $q.defer();
$http.get(imgurl, {

.then(function mySuccess(response) {

console.log(response.status);
if (response.status == 404) {
$scope.cards.splice(card, 1);
}
// console.log('deleted');
var imgpid = "#card-image-" + card.vari;
console.log(imgpid);
$(imgpid).parent().remove();
})
.catch(function(err) {
});
$timeout(function() {
$ionicLoading.hide();
canceler.resolve();
}, 4000);
});
})

我改变了这一行:
<img class="storelogo-image" ng-src="{{card.store__logo}}">
到
<img class="storelogo-image" ng-src="{{card.store__logo.indexOf('http://')> -1 ?card.store__logo :''}}">
它运作正常。

我将ng-if="card.image"
添加到<td-card ng-if="card.image" ng-repeat="card in cards"
...
如果没有可用的图像,这将阻止模板生成并清空图像模板
