javascript - Angular 文件上传更新范围 onCompleteItem

Question

所以我在我的范围内有一个名为 $scope.selectedComponent

的值

然后我有以下 uploader :

    var uploader = $scope.uploader = new FileUploader({
    url: 'user_resources/upload.php',
    formData: [{module_id: $state.params.id, component: $scope.selectedComponent}]
});

// FILTERS

uploader.filters.push({
    name: 'customFilter',
    fn: function(item /*{File|FileLikeObject}*/, options) {
        return this.queue.length < 10;
    }
});

// CALLBACKS

uploader.onWhenAddingFileFailed = function(item /*{File|FileLikeObject}*/, filter, options) {
    console.info('onWhenAddingFileFailed', item, filter, options);
};
uploader.onAfterAddingFile = function(fileItem) {
    console.info('onAfterAddingFile', fileItem);
};
uploader.onAfterAddingAll = function(addedFileItems) {
    console.info('onAfterAddingAll', addedFileItems);
};
uploader.onBeforeUploadItem = function(item) {
    console.info('onBeforeUploadItem', item);
};
uploader.onProgressItem = function(fileItem, progress) {
    console.info('onProgressItem', fileItem, progress);
};
uploader.onProgressAll = function(progress) {
    console.info('onProgressAll', progress);
};
uploader.onSuccessItem = function(fileItem, response, status, headers) {
    console.info('onSuccessItem', fileItem, response, status, headers);
};
uploader.onErrorItem = function(fileItem, response, status, headers) {
    console.info('onErrorItem', fileItem, response, status, headers);
};
uploader.onCancelItem = function(fileItem, response, status, headers) {
    console.info('onCancelItem', fileItem, response, status, headers);
};
uploader.onCompleteItem = function(fileItem, response, status, headers) {
    console.info('onCompleteItem', fileItem, response, status, headers);
};
uploader.onCompleteAll = function() {
    console.info('onCompleteAll');
};

callback 函数:onCompleteItem 是我想更新 selectedComponent 对象的地方，但是在该函数的范围内我无法获取scope

的变量

我的问题是文件上传后如何更新我的变量？

确保 $scope 已加载到您的 Controller 中:

.controller('AppController', ['$scope', 'FileUploader', function($scope, FileUploader) {

然后你可以从这个 Controller 的任何地方更新 $scope.selectedComponent 的值。

$scope.selectedComponent = "not uploaded";

    uploader.onCompleteItem = function (fileItem, response, status, headers) {
                  $scope.selectedComponent = "upload complete";
};
