如何使用angular js？

从存储在json文件中的URL获取/显示外部媒体内容

JSON

"media": [
        {
          "title": "Example_1",
          "url": "http://www.w3schools.com/html/mov_bbb.mp4"
        },
        …….
]

控制器

controller('Controller', ['$scope','$http', function($scope, $http) {
   $http.get('myjson.json').success(function (data){

        $scope.medianew = data.media;

     });

HTML

<div class="panel-body" ng-repeat = "md in medianew">                           
      <video ng-src="{{md.url}}" width="240" controls></video>
</div>

我无法显示外部来源的媒体。我在这里做错了什么？

您的问题与此one.

有些相似

您需要使用角度来看import UIKit import Charts class CombinedChartsTest: UIViewController { @IBOutlet weak var combinedChart: CombinedChartView! let months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"] let unitsSold = [2.0, 4.0, 6.0, 3.0, 12.0, 16.0, 4.0, 17.0, 2.0, 4.0, 5.0, 4.0] override func viewDidLoad() { super.viewDidLoad() setChart(months, yValuesLineChart: unitsSold, yValuesBarChart: unitsSold) } func setChart(xValues: [String], yValuesLineChart: [Double], yValuesBarChart: [Double]) { combinedChart.noDataText = "Please provide data for the chart." var yVals1 : [ChartDataEntry] = [ChartDataEntry]() var yVals2 : [BarChartDataEntry] = [BarChartDataEntry]() for i in 0..<xValues.count { yVals1.append(ChartDataEntry(value: yValuesLineChart[i], xIndex: i)) yVals2.append(BarChartDataEntry(value: yValuesBarChart[i] - 1, xIndex: i)) } let lineChartSet = LineChartDataSet(yVals: yVals1, label: "Line Data") let barChartSet: BarChartDataSet = BarChartDataSet(yVals: yVals2, label: "Bar Data") let data: CombinedChartData = CombinedChartData(xVals: xValues, dataSets: [lineChartSet,barChartSet]) combinedChart.data = data } }服务。我做了一个plnkr来解决你的问题。

基本上，您需要将myfns () { local fun declare -F | while read -r _ _ fun; do case :$SYSFNS: in *:"$fun":*) continue;; esac echo "$fun" done }文件的内容解析为json内容。
