我有一个包含值列表的数组.

 [Object { id="5", country="UAE"}, Object { id="4", country="India"}]

我想根据id中的值获取数组项的索引.如何在angularJS控制器中获取值为id = 4的数组项的索引位置？

我有一个表单只使用angularJS上传图像文件.上传文件一切正常.问题是,我想将上传的文件限制为仅图像文件,并将图像的大小限制为一些MB.如何仅使用angularJS实现此目的？下面是代码

$scope.uploadFile = function(files) {
    var fd = new FormData();
    //Take the first selected file
    fd.append("file", files[0]);

    $http.post("logoTypesServiceStore", fd, {
        withCredentials: true,
        headers: {'Content-Type': undefined },
        transformRequest: angular.identity
    }).success( function(data) {alert(data); }).error( function(data) { alert(data)});

};  

以下是上传文件的表格.

 <form name="logoTypeForm" novalidate>
     <input type="text" name="logoType" ng-model="logoType" class="form-control" required />
     <input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/>

 </form>

我曾经用于Paginator::make对表中的记录进行分页.在视图中,我正在获取分页链接,但每个链接都包含其中的所有记录.如何将其限制为perPage项目？

    $datas = Paginator::make($paginator, count($paginator), $perPage);
    return $datas;

代码输出:

{"total":10,"per_page":5,"current_page":1,"last_page":2,"from":1,"to":5,"data":

我的路线:

Route::group(array("namespace" => "languages"),function(){
   Route::resource("languagesService", "languageServiceController");
   Route::resource("languages","languageController");
});

languageservicecontroller和languagecontroller是子文件夹语言.

在登录尝试期间,我保存了用户名和密码

Session::put('username', $user['username']);
Session::put('password', $user['password']);

但是当我尝试从languageController中检索时

$username = Session::get('username');
$password = Session::get('password');

我得到了以下错误

"类'语言\会话'未找到".
