Directives(指令)

  • nv-file-drop

属性 uploader 必须是 FileUploader的一个实例。
属性 options 可能是 {FileItem} 的设置或者自定义设置。
属性 filters 可能是用,隔开的过滤器名称比如: 'filterName1, filterName2',这些过滤器必须如下预定义:

uploader.filters.push({name:'filterName1', fn:function() {/* your code here */}});uploader.filters.push({name:'filterName2', fn:function() {/* your code here */}});
  • nv-file-select

  • nv-file-over

Service(服务)

  • FileUploader

FileUploader

属性

  • url {String}: 上传文件的服务器路径

  • alias {String}: 包含文件的名称,默认是file

  • queue {Array}: 上传队列

  • progress {Number}: 上传队列的进度,只读

  • headers {Object}: 上传的头文件信息, 浏览器需支持HTML5

  • formData {Array}: 与文件一起发送的表单数据

  • filters {Array}: 在文件加入上传队列之前应用过滤器.,如果过滤器返回true则文件加入队列中

方法

  • addToQueue function(files[, options[, filters]]) {: Add items to the queue, where files is a {FileList|File|HTMLInputElement}, options is an {Object} andfilters is a {String}. 添加项到上传队列中,files{FileList|File|HTMLInputElement}, options{Object} 以及 filters{String}

  • removeFromQueue function(value) {: Remove an item from the queue, wherevalue is {FileItem} or index of item. 从上传队列移除项,value 可以是 {FileItem} 或者项的序号

  • clearQueue function() {: Removes all elements from the queue. 移除上传队列所有的元素

  • uploadItem function(value) {: Uploads an item, where value is {FileItem} or index of item. 上传项, value 可以是 {FileItem} 或者项的序号

  • getIndexOfItem function({FileItem}) {return {Number};}: Returns the index of the{FileItem} queue element. 返回项在上传队列中的序号

  • getReadyItems function() {return {Array.};}: Return items are ready to upload. 返回准备上传的项

  • getNotUploadedItems function() {return {Array.};}: Return an array of all pending items on the queue 返回上传队列中未上传的项

回调函数

  • onAfterAddingFile function(item) {: 添加文件到上传队列后
