我有一个文件上传按钮，上传后我希望所选的文件名出现在下面的行中，使用 Angular ngRepeat，
但是列表没有出现。
这是我的代码:
var pniotApp = angular.module('pniotApp', []);
pniotApp.controller('pniotCtrl', function ($scope, $http, $location) {
$scope.fileSelected = function (element) {
$scope.files = element.files;
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body dir="rtl" ng-app="pniotApp" ng-controller="pniotCtrl">
<input id="uploadFile" type="file" class="filestyle" data-classButton="btn btn-primary" multiple data-input="false" data-classIcon="icon-plus" onchange="angular.element(this).scope().fileSelected(this)" data-buttonText="עיון...">
<ul>
<li ng-repeat="file in files">{{file.name}}</li>
</ul>
</body>console.log($scope.files[0].name);
列表中没有出现的原因可能是什么？
最佳答案
您忘记定义 $scope.files。
var pniotApp = angular.module('pniotApp', []);
pniotApp.controller('pniotCtrl', function ($scope, $http, $location) {
$scope.files=[];
$scope.fileSelected = function (element) {
$scope.files = element.files;
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body dir="rtl" ng-app="pniotApp" ng-controller="pniotCtrl">
<input id="uploadFile" type="file" class="filestyle" data-classButton="btn btn-primary" multiple data-input="false" data-classIcon="icon-plus" onchange="angular.element(this).scope().fileSelected(this)" data-buttonText="עיון...">
<ul>
<li ng-repeat="file in files">{{file.name}}</li>
</ul>
