我有一个 JSON 数据数组，它是来自 Clarifai 识别的 predict(...) 调用的响应，我正在尝试在 HTML 中显示该数据数组。我使用 ng-repeat 来显示数组，但它不起作用。如何在 HTML 中显示数组？下面是我的 JS 文件和 HTML 文件的代码片段。
var app = angular.module("starter",['ionic']);
app.controller("myCtrl", function($scope,$rootScope) {
const app = new Clarifai.App({ apiKey: 'e7f899ec90994aeeae109f6a8a1fafbe' });
$rootScope.records = [];
// predict the contents of an image by passing in a url
app.models.predict("pets",'https://samples.clarifai.com/puppy.jpeg').then(
function(response) {
// The JSON.stringify() method converts a JavaScript value to a
// JSON string optionally replacing values if a replacer function
// is specified, or optionally including only the specified
// properties if a replacer array is specified.
for(var i=0; i < 2; i++) {
$rootScope.records[i] = JSON.stringify(response.outputs[0].data.concepts[i].name);
console.log(`module concept = ${$rootScope.records[i]}`);
alert($rootScope.records[i]);
}
},
function(err) {
console.error(err);
}
);

我建议手动触发摘要周期，因为您的 predict 调用是异步的。
// add a reference to $timeout
app.controller("myCtrl", function($scope, $rootScope, $timeout) {
// ...
// predict the contents of an image by passing in a url
app.models.predict("pets",'https://samples.clarifai.com/puppy.jpeg').then(
function(response) {
for(var i=0; i < 2; i++) {
$rootScope.records[i] = JSON.stringify(response.outputs[0].data.concepts[i].name);
console.log(`module concept = ${$rootScope.records[i]}`);
// add the following $timeout call to manually trigger a digest cycle
$timeout(() => {}); /* OR */ $scope.$digest();
}
},
function(err) {
console.error(err);
}
);
});
