大佬教程收集整理的这篇文章主要介绍了angular fileUploader 中文API，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

Directives（指令）
nv-file-drop
<!-- 最少配置 -->
<elementnv-file-dropuploader="{FileUploader}"></element>
<!-- 最多配置 -->
<elementnv-file-dropuploader="{FileUploader}"options="{Object}"filters="{String}"></element>
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
<!-- 最少配置 -->
<inputtype="file"nv-file-SELEctuploader="{FileUploader}"/>
<!-- 最多配置 -->
<inputtype="file"nv-file-SELEctuploader="{FileUploader}"options="{Object}"filters="{String}"/>
nv-file-over
<!-- 最少配置 -->
<elementnv-file-overuploader="{FileUploader}"></element>
<!-- 最多配置 -->
<elementnv-file-overuploader="{FileUploader}"over-class="{String}"></element>

API使用举例：

var uploader = $scope.uploader = new FileUploader({
    url: $scope.fileUploadUrl
  });

  uploader.filters.push({
    name: 'customFilter',fn: function(item,options) {
      if(item.size > 100*1024*1024){
        toaster.pop("error","错误","文件过大,请限制文件在100M以内");
        return false;
      }
      return true;
    }
  });
  uploader.onAfterAddingFile = function(item){
    item.url = $scope.fileUploadUrl;
    angular.forEach(uploader.queue,function(f){
      if(f.file.name != item.file.Name)uploader.removeFromQueue(f);
    })
  }
  uploader.onBeforeUploadItem = function(item){
    toaster.clear();
    toaster.pop("wait","信息","文件正在上传,请稍等....");
  }
  uploader.onsuccessItem = function(item,headers) {
    toaster.clear();
    if(response.result == 1){
      var zTree = $.fn.zTree.getZTreeObj("ztree");
      zTree.addNodes($scope.SELEctNode,{id:response.obj.id,pId:$scope.SELEctNode.id,name:response.obj.namE});
      toaster.pop("success","文件上传并解析成功");
    } else toaster.pop("error",response.msg);
  };
