我设法将我的json文件中的所有图像加载到应用程序中,但我只想加载1张图像。我使用ng-repeat这就是为什么它不断重复。我用什么替换ng-repeat所以它只显示第一张图像?
这是我的代码。
HTML:
<div ng-click="onClick()">
<i class="ion-images"></i>
</div>
<a ng-controller="Ctrl">
<ion-scroll direction="x">
<img on-hold="onHold()" ng-repeat="image in data" ng-src="{{image.image}}" />
</ion-scroll>
</a>
js:
.controller(&#34; Ctrl&#34;,function($ scope,$ http,$ ionicModal){
$scope.data = [];
$http.get('')
.success(function(data) {
$scope.data = data;
window.localStorage.setItem("images", JSON.stringify(data));
})
});

如果您只希望显示阵列中的第一个元素,则不能使用ng-repeater,您可以使用数组索引访问它,即:
ng-src="{{data.under9s[0].image}}
请参阅下面的工作演示:
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, $http) {
$scope.data = [];
$http.get('https://api.myjson.com/bins/4tutm')
.success(function(data) {
$scope.data = data;
window.localStorage.setItem("images", JSON.stringify(data));
})
.error(function(error) {
if (window.localStorage.getItem("images") !== undefined) {
$scope.data = JSON.parse(window.localStorage.getItem("images"));
}
});
});
