上传文件时遇到问题。我创建了一项服务:
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};}]);
然后我有一个指令:
$scope.uploadFile = function(){
var file = $scope.myFile;
console.log('file is ' );
console.dir(file);
var uploadUrl = "/fileUpload";
fileUpload.uploadFileToUrl(file, uploadUrl);
};
在控制器中:
Browse <input type="file" file-model="myFile"/>
<button ng-click="uploadFile()">upload me</button>
HTML:
Caused by: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.ejb.entidades.Provincia.ciudades[com.ejb.entidades.Ciudad]
正如您所看到的,我在控制器中使用console.log,而我正在使用的是
文件未定义
提前致谢!

更改
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
scope: {
percent: "=fileModel"
},
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
scope.$watch('percent', function(value) {
console.log(value)
});
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};}]);
在上传文件
后检查百分比监视内的控制台值
