这是我的HTML表单:
<form name="myForm" ng-submit="">
<input ng-model='file' type="file"/>
<input type="submit" value='Submit'/>
</form>
我想从本地机器上传一个图像，并想读取上传文件的内容。所有这些我都想用AngularJS来做。
当我试图打印$scope的值时。文件是未定义的。

下面是文件上传的工作示例:
http://jsfiddle.net/vishalvasani/4hqVu/
在这个函数中
setFiles
从视图更新控制器中的文件数组
or
你可以使用AngularJS检查jQuery文件上传
http://blueimp.github.io/jQuery-File-Upload/angularjs.html
这是现代浏览器的方式，没有第三方库。适用于所有最新的浏览器。
app.directive('myDirective', function (httpPostFactory) {
return {
restrict: 'A',
scope: true,
link: function (scope, element, attr) {
element.bind('change', function () {
var formData = new FormData();
formData.append('file', element[0].files[0]);
httpPostFactory('upload_image.php', formData, function (callback) {
// recieve image name to use in a ng-src
console.log(callback);
});
});
}
};
});
app.factory('httpPostFactory', function ($http) {
return function (file, data, callback) {
$http({
url: file,
method: "POST",
data: data,
headers: {'Content-Type': undefined}
}).success(function (response) {
callback(response);
});
};
});
HTML:
<input data-my-Directive type="file" name="file">
PHP:
如果收取(带有_file美元['文件'])& & $带有_file(“文件”)(“错误”)= = 0){ //上传images文件夹中的image $temp =爆炸("."，$_FILES["file"]["name"]); $newfilename = substr(md5(time())， 0,10)。”。”。结束(临时); 函数(带有_file美元(“文件”)(“tmp_name”),“图像/”。美元newfilename); //给你的angular代码回调图像SRC名称 回声json_encode ($ newfilename); ｝ Js小提琴(仅前端) https://jsfiddle.net/vince123/8d18tsey/31/
我想这是angular文件的上传:
ng-file-upload
用来上传文件的轻量级Angular JS指令。
这里是演示页面。特性
Supports upload progress, cancel/abort upload while in progress, File drag and drop (html5), Directory drag and drop (webkit), CORS, PUT(html5)/POST methods, validation of file type and size, show preview of selected images/audio/videos. Cross browser file upload and FileReader (HTML5 and non-HTML5) with Flash polyfill FileAPI. Allows client side validation/modification before uploading the file Direct upload to db services CouchDB, imgur, etc... with file's content type using Upload.http(). This enables progress event for angular http POST/PUT requests. Seperate shim file, FileAPI files are loaded on demand for non-HTML5 code meaning no extra load/code if you just need HTML5 support. Lightweight using regular $http to upload (with shim for non-HTML5 browsers) so all angular $http features are available
