Checkout如何過濾器被用於一些實施例的源代碼上(https://github.com/nervgh/angular-file-upload/blob/master/src/module.js#L51)
this.filters.unshift({name: 'queueLimit', fn: this._queueLimitFilter});
this.filters.unshift({name: 'folder', fn: this._folderFilter});
隊列限制濾波器(https://github.com/nervgh/angular-file-upload/blob/master/src/module.js#L357)
FileUploader.prototype._queueLimitFilter = function() {
return this.queue.length < this.queueLimit;
};
文件夾篩選(https://github.com/nervgh/angular-file-upload/blob/master/src/module.js#L349)
FileUploader.prototype._folderFilter = function(item) {
return !!(item.size || item.type);
};
基於那些例子mples我想濾波器可以用作例如:
的javascript
var uploadOptions = {
url: '/whatever/uploadfile',
filters: []
};
// File must be jpeg or png
uploadOptions.filters.push({ name: 'imagefilter', fn: function(item) {
return item.type == 'image/jpeg' || item.type == 'image/png';
}});
// File must not be larger then some size
uploadOptions.filters.push({ name: 'sizeFilter', fn: function(item) {
return item.size < 10000;
}});
$scope.uploadOptions = uploadOptions;
