//Create an Angular Module.
var newsModule = angular.module('NewsModule', []);

//Create an Angular Controller.
newsModule.controller('newsCtrl', ['$scope', '$http', function ($scope, $http) {
//function retrives POST,UPDATE,DELETE,GET data

$http.defaults.headers.put = {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': 'GET, POST, PUT, DELETE, OPTIONS',
        'Access-Control-Allow-Headers': 'Content-Type, X-Requested-With'
        };
        $http.defaults.useXDomain = true;

    $scope.throughdata = function (){

 delete $http.defaults.headers.common['X-Requested-With'];
         $http.get('http://www.google.com').then(function(data,error){
            alert(data);
            alert(error);
            $scope.days=data.data;
          });



    }
}
 ]);

但我有以下错误

XMLHttpRequest无法加载http://www.google.com/.请求的资源上不存在"Access-Control-Allow-Origin"标头.因此不允许原点'null'访问.

当用户输入正确的用户名和密码时,我想重定向到另一个位置.但是当我$location.path('dashboard')在这里使用时,浏览器的URL被更改但是该页面没有被加载.当使用ctrl + R刷新我的页面或者点击浏览器的刷新图标然后加载适当的页面.

$http.post('/login', $scope.userInfo)
        .success(function (data) {
            //Check if the authentication was a success or a failure
            //Successful POST here does not indicate success of authentication
            if (data.status === "authentication success") {

                //Proceed to load the dashboard for the user                    
                $location.path('/dashboard');

            } else if (data.status === "authentication error") {
                //Inform user of the error
                $scope.errorMessage = data.error;
                $scope.showErrorMessage = true;
            }

        })
        .error(function (error) {
            $scope.errorMessage = "Error while attempting to authenticate. Check  log.";
            $scope.showErrorMessage = true; …

我用这种方式上传文件:

  <input type="file" 
         name="upload-file" 
         ng-model= "excelFile" 
         accept=".xlsx" 
         onchange="angular.element(this).scope().fileChanged(this);"
         required="true" 
  />

在控制器中创建fileChanged方法

 $scope.fileChanged = function(files) {
     $scope.excelFile = files[0];
 };

它适用于FireFox,Chrome IE10,IE11,但在IE9中它显示"文件为null我们未定义".
