上传Excel文件代码demo：
下载上传js文件：bower install ng-file-uploa；引入js文件；
angular.module(‘dc.workflow‘, [
???‘ngFileUpload‘
]);
js代码：
var data=this.data={file:null};
//定义data.file为空；
this.selectImage = function (file) {
???this.errorFileType = false;
???if (file[0].type != ‘application/vnd.openxmlformats-officedocument.spreadsheetml.sheet‘) {
???????this.errorFileType = true;
???}
};
//判断上传文件类型，定义errorFileType为false，if()里面为判断条件，判断条件为非的时候（也就是条件不成立），errorFilterType为true；
上传文件正确时（也就是条件成立）获取上传的文件的所有信息，包括文件名称，大小，格式等等，储存在file里面；this.importFile = function (ev) {
???if (this.errorFileType || !data.file) {
???????this.errorFileType = true;
???????return
???}
//这里是判断上面条件不成立的时候直接return，不执行下面的代码；
???Upload.upload({
???????url: commonSvc.baseURlForDCBulk + ‘api/import/‘ + templateId,
???????data: {ExcelFile: data.file}
//条件成立，上传文件到固定的接口地址，并且获取上传文件
???}).then(function (result) {
???????//上传文件成功后所执行的代码
???????$mdDialog.hide();
???????$mdDialog.show({
???????????controller: ‘tableDataImportSuccessModalCtrl‘,
???????????controllerAs: ‘$ctrl‘,
???????????templateUrl: ‘modal/data-import-export/table-data-import-success-modal.html‘,
???????????parent: angular.element(document.body),
???????????targetEvent: ev,
???????????locals: {},
???????????clickOutsideToClose: false,
???????????fullscreen: false // Only for -xs, -sm breakpoints.
???????}).then(function (result) {
???????});
???}).catch(commonSvc.translateHttpError);
};
