我正在使用教程中的代码并对其进行了一些修改。我遇到了编辑功能的问题。我不断收到“ReferenceError:$modal 未定义”这是我的代码。

postCtrl:

app.filter('startFrom', function() {
    return function(input, start) {
        if(input) {
            start = +start; //parse to int
            return input.slice(start);
        }
        return [];
    }
});
app.filter('dateToISO', function() {
  return function(input) {
    input = new Date(input).toISOString();
    return input;
  };
});
app.controller('postsCtrl', function ($scope, $log, $http, $timeout, Data) {
    Data.get('posts').then(function(data){
        $scope.posts = data.data;
        $scope.currentPage = 1; //current page
        $scope.filteredItems = $scope.posts.length; //Initially for no filter  
        $scope.totalItems = $scope.posts.length;
        $scope.list_pages = [
                {
                    id: '5',

如有任何帮助，我们将不胜感激。

最佳答案

你没有在 postsCtrl Controller 中注入(inject) $modal 依赖

app.controller('postsCtrl', function ($scope, $log, $http, $timeout, Data, $modal) {

Make sure you have injected particular dependency before getting access to it. Assuming you have already added ui.bootstrap module dependency too.

更新

如果您使用的是 0.14.X 的最新版本的 Angular ui bootstrap，则需要注入(inject) $uibModal 而不是 $modal。当他们重命名所有 boostrap 指令和 serviec 名称前加上 uib 前缀。

$modalInstance 依赖也会发生同样的事情，需要更改为 $uibModalInstance

关于javascript - Angular 错误 - ReferenceError : $modal is not defined，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36071978/
