我正在查看JQuery File上传的angular插件的源代码,我看到以下代码:
angular.module('blueimp.fileupload', [])
// The fileUpload service provides configuration options
// for the fileUpload directive and default handlers for
// File Upload events:
.provider('fileUpload', function () { ... })
.controller('FileUploadController', [
'$scope', '$element', '$attrs', '$window', 'fileUpload',
function ($scope, $element, $attrs, $window, fileUpload) {
...
// Observe option changes:
$scope.$watch(
$attrs.fileUpload,
function (newOptions) {
if (newOptions) {
$element.fileupload('option', newOptions);
}
}
);
所以我觉得这个模块似乎是为了让我能够更新fileupload小部件上的选项(这就是$ element.fileupload('option',...)所做的);但是,我不知道如何进入$ attrs.fileUpload。
我需要在控制器中执行异步调用后将选项更新为fileupload:
var accountEditor = angular.module('accountEditor', [ 'ngResource', 'blueimp.fileupload' ]);
accountEditor.controller('accountEditorCtrl', [
'$scope',
'$resource',
'fileUpload',
function($scope, $resource, fileUpload) {
doAsyncThing(function() {
// update options...what goes here?
});
我当前的解决方案是一个黑客攻击,它会混淆事件回调的选项(如How to change dynamically the upload (jquery-file-upload) url using $scope?中所述)。我认为这是一个黑客攻击,因为它需要用户交互来设置选项,并且还会导致在异步调用完成之前可能发生用户交互的竞争条件。

你有观看代码吗?
我想你需要更新控制器上的options属性。
e.g。
查看:
<div data-ng-controller="accountEditorCtrl">
<form data-ng-controller="FileUploadController" data-file-upload="options">
</options>
</div>
控制器:
var accountEditor = angular.module('accountEditor', [ 'ngResource', 'blueimp.fileupload' ]);
accountEditor.controller('accountEditorCtrl', [
'$scope',
'$resource',
'fileUpload',
function($scope, $resource, fileUpload) {
$scope.options = {}; // Set options here
doAsyncThing(function() {
$scope.options = {}; // Update options
// Note if this async method is not handled by angular you may need
// to call $scope.$apply(); to notify angular of the changes to scope
});
