Question

我想要做的是从控制器功能更新AngularJS变量，当我立即更新它时更新它，但是当我打印它时大约5-8秒后查看它更新。

我尝试使用ng-model和花括号，但在两种情况下都会在视图中显示几秒钟，但在控制台中会立即更新。

我在上传回调中调用了uploadMedia函数，并且在console.log

中正常工作

$scope.UploadedMedia = function(){
      console.log($scope.Album[0].Media.length);
      $scope.UploadedMediaVal = $scope.Album[0].Media.length;
      console.log($scope.Album[0].Media.length);
    }

$scope.initFineUploader = function(){
  var fcnt = 0;
  var iuploader = new qq.FineUploaderBasic({
        multiple: true,
        autoUpload: true,
        title: "Attach Photos",
        button: $("li[data-type='uploadMediabutton']")[0],
        request: {
            endpoint: site_url + "api/uploadimage",
            customHeaders: {
                "Accept-Language": accept_language
            },
            params: {
                Type: 'ratings',
                unique_id: function() {
                    return '';
                },
                LoginSessionKey:LoginSessionKey,
                DeviceType:'Native'
            }
        },
        maxConnections : 50,
        validation: {
            acceptFiles: '.bmp,.jpeg,.jpg,.gif,.png',
            allowedExtensions: ['bmp','jpeg', 'jpg', 'gif', 'png', 'JPEG', 'JPG', 'GIF', 'PNG'],
            sizeLimit: 4194304 // 40mb
        },
        callbacks: {
            onUpload: function(id, fileName) {
                $scope.Album[0].Media.push({MediaGUID:'',ImageName:'',Caption:'',MediaType:'Image',VideoLength:'',ConversionStatus:'',IsLoader:'1',FileName:fileName});
                $scope.UploadedMedia();
                $('.rating-submit').attr('disabled','disabled');
                fcnt++;
            },
            onProgress: function(id, fileName, loaded, total) {
                $scope.Uploading = 1;
            },
            onComplete: function(id, fileName, responseJSON) {
                fcnt--;
                if (responseJSON.Message == 'Success') {
                  $($scope.Album[0].Media).each(function(mk,mv){
                    if(mv.FileName == fileName){
                      $scope.Album[0].Media[mk]['MediaGUID'] = responseJSON.Data.MediaGUID;
                      $scope.Album[0].Media[mk]['ImageName'] = responseJSON.Data.ImageName;
                      $scope.Album[0].Media[mk]['IsLoader'] = 0;

                    }
                  });
                  var fNameExt = fileName.substr(fileName.lastIndexOf('.') + 1);
                  $('li[data-filename="'+fileName+'"]').remove();
                  setTimeout(function(){

                  },1000);
                } else {
                    $('li[data-filename="'+fileName+'"]').remove();
                }
                if(fcnt <= 0){

                  showResponseMessage('You can upload maximum 10 images, please delete any old image to upload new one.','alert-danger');
                  return false;
                }
                var validExtensions = ['bmp','jpeg', 'jpg', 'gif', 'png', 'JPEG', 'JPG', 'GIF', 'PNG']; //array of valid extensions

Answer 1

修改变量后写$scope.$apply();。

Answer 2

如何调用SomeOtherFunction？是在角度摘要阶段还是在dom事件中触发。在第二种情况下，您必须使用$scope. $apply (){}

包装命令

AngularJS变量不会立即反映在View上，而是在Controller上更新
